Governments and public health organizations need to be prepared to detect and respond to a biological attack, to minimize the impact on public health and safety.

What Are Biological Warfare Agents?

Biological warfare agents are disease-causing living organisms or toxins that can be used to harm or kill humans, animals or plants.

Some examples of biological warfare agents include:

• Bacteria, such as anthrax and bubonic plague
• Viruses, such as Ebola and smallpox
• Toxins produced by living organisms, such as botulinum toxin and ricin
• other biological warfare agents (e.g. fungi, prions or rickettsiae, etc.).

These agents can be disseminated, among other, through the air, water, or food. Also, they can be spread by direct contact with an infected person or animal.

International treaties banned the use of biological warfare agents as weapons, and it is considered a war crime to use them in armed conflict. However, there is still a risk that they could be used by terrorists or rogue states.

History of Biological Warfare Agents Use

The use of biological agents as weapons has a long history, dating back to ancient times.

“Biological warfare has a long history, dating back to ancient times, when the Assyrians poisoned enemy wells with rye ergot, a fungus that causes hallucinations and death”

Ackerman, G. & Moran, M.

Antiquity & Middle Ages

• 6th century BC: Perhaps one of the earliest reported and most simple uses of a biological agent in warfare is from the 6th century BC, when Assyrian armies used a toxin derived from ergot-infected rye to poison the water wells of besieged enemies.
• 400 BC: Another unique and innovative use of biological agents is reported from around 400 BC, in which it was the practice of Scythian archers to dip the heads of their arrows into vats of bacteria-rich human excrement and decomposing corpses.
• In the Middle Ages: the Tartars threw the bodies of plague victims over the walls of the besieged city of Kaffa in an attempt to spread the disease.
• 16th century: In Africa, biological agents such as poisoned arrows and powders were used, as well as the poisoning of horses and water supplies.  
• The Great Northern War: Russians under the leadership of Peter the Great exploited the same “biological pathogen” delivery methods that the Tartars used, catapulting plague-infected corpses, against the Swedes.

18th to 19th century

• June 1763: During the French and Indian War, it is reported that the commander of Fort Pitt ordered his men to give smallpox-infested blankets to a Native American delegation during a siege.
• This resulted in an outbreak of smallpox that killed number of Native Americans. It is unclear whether the smallpox was a result of this incident or whether the virus was already present among the Native American population.

• During the American Revolutionary War: there were rumors that the British tried to spread smallpox to American lines by sending civilians out of the city during the Siege of Boston. However, these rumors were not substantiated.
• In 1789: Some historians have also claimed that smallpox was deliberately used by a detachment of the Corps of Royal Marines in Australia.

World War I

• By the early 20th century, advances in science had led to a greater understanding of the potential use of biological agents in warfare.
• During World War I, the Imperial German government is reported to have carried out biological sabotage using anthrax and glanders, but with little success. The Geneva Protocol of 1925 was established to prohibit the use of chemical and biological weapons.

World War II

During World War II, Japan’s Unit 731 conducted experiments on prisoners of war, testing the effects of biological warfare agents such as anthrax and bubonic plague.

Williams, P.

• During World War II, the United Kingdom established a biological warfare program at Porton Down and successfully weaponized several agents, including tularemia, anthrax, brucellosis, and botulism toxins.
• The United States also established a large research program and industrial complex at Fort Detrick and conducted tests at the Dugway Proving Grounds in Utah.
• Japan’s Imperial Army Unit 731 conducted human experiments and produced biological weapons for combat use, often targeting Chinese soldiers and civilians with diseases such as the bubonic plague.
• There were also plans to use plague as a weapon against U.S. civilians in California, but the attack was never carried out due to Japan’s surrender.

Cold War

In the Cold War era, the United States and the Soviet Union both developed large stockpiles of biological warfare agents, raising concerns about the potential for accidental release or unauthorized use

Zilinskas, R.

• In the 1950s, the United Kingdom developed weaponized versions of plague, brucellosis, tularemia, and equine encephalomyelitis and vaccinia viruses, but the program was ended in 1956. The United States also developed weaponized versions of anthrax, tularemia, brucellosis, and Q-fever.
• In 1969, President Nixon ended the offensive biological weapons program of the US, allowing only research for defensive purposes.
• This decision led to negotiations for a ban on biological warfare, which resulted in the signing of the Biological Weapons Convention (BWC) in 1972 and its entry into force in 1975.
• Despite being a party to the BWC, the Soviet Union allegedly continued and expanded its biological weapons program under the leadership of the institution Biopreparat.
• The Soviet Union faced international suspicion following the 1979 Sverdlovsk anthrax leak, which killed approximately 65 to 100 people.

The Biological and Toxin Weapons Convention (BTWC) prohibits the development, production, acquisition, stockpiling, retention, transfer or use of biological weapons, and it is enforced by 162 state parties, however, the continued existence of a number of potential and actual violators underlines the challenges of enforcement

Kellman, B.

Types of Biological Warfare Agents

There are many different types of biological warfare agents, including bacteria, viruses, fungi, prions, rickettsia, and toxins produced by living organisms.

“Bacteria have been used as biological warfare agents for centuries, with the earliest recorded use dating back to the 14th century, when the Tatars used plague-infested corpses to infect the Mongol army”

Kelly, D.M.

Some specific examples of biological warfare agents (biological pathogens identified as likely to have been weaponized and/or used as biological terrorism threat agents) include:

Bacterial Biological Warfare Agents

Bacterial biological warfare agents are types of bacteria that can be used as weapons to kill or incapacitate people, livestock, or crops. Some examples of bacterial biological warfare agents include:

“The development of antibiotic resistance in common bacterial pathogens such as Staphylococcus aureus and Escherichia coli has raised concerns about the potential for these organisms to be used as biological warfare agents”

Chen, L.

Viral Biological Warfare Agents

Viral biological warfare agents are types of viruses that can be used as weapons to kill or incapacitate people, livestock, or crops. Some examples of viral biological warfare agents include:

“Viruses have long been seen as attractive agents for biological warfare because of their ability to cause severe disease and spread rapidly”

Dowdle, W. R.

Toxins as Biological Warfare Agents

Toxins are substances produced or derived from living organisms, both animal and plant, such as bacteria, cyanobacteria, fungi, and some species of plants and marine fish, that cause disease pathology or other debilitating response in humans and other animals, and that can be used as weapons.

Next to the BWC, the Chemical Weapons Convention (CWC) covers some toxins as CWA also. Here are some examples of toxins:

Biological Warfare Agents Types by Target

Biological warfare agents can be categorized by the type of organism or toxin used, and also by the target they are designed to affect, as well as according to their lethality and their transmissibility. Here are some examples of common types of biological warfare agents grouped by target:

“Biological warfare agents can be divided into three main categories: those that target humans, those that target animals, and those that target plants”

Smyth, A.

1. Human pathogens: These include bacteria, viruses, and other microorganisms that can cause disease in humans. Examples include anthrax, smallpox, and plague.
2. Animal pathogens: These include microorganisms that can cause disease in animals. Examples include foot-and-mouth disease and avian influenza.
3. Plant pathogens: These include microorganisms that can cause disease in plants. Examples include rice blast fungus and wheat stem rust.

It’s important to note that some agents can target multiple types of organisms, for example anthrax can infect both humans and animals, and toxins like ricin can be used to target both animals and humans. It is also worth noting that the effects of biological warfare agents can depend on a variety of factors, including the type and dose of the agent, the method of exposure (e.g., inhalation, ingestion, injection), and the individual characteristics of the person or organism exposed (e.g., age, health status).

What is Bioterrorism?

Bioterrorism is the intentional release of biological agents (such as bacteria, viruses, or toxins) to cause illness or death in people, animals, or plants.

“Bioterrorism attacks can be difficult to detect and respond to because the symptoms of a biological agent may not appear for days or even weeks after exposure”

Centers for Disease Control and Prevention

These agents can be naturally occurring or genetically modified to increase their virulence (ability to cause disease) or resistance to treatment.

Bioterrorism can be carried out by individuals, groups, or governments, and can have significant impacts on public health and national security.

The threat of bioterrorism has increased in recent years due to the ease of access to information about how to produce and disseminate some biological agents, and the potential for these agents to be used as weapons of mass destruction.

Which Biological Agent can be Used in Bioterrorism?

Biological agents that could potentially be used in bioterrorism include bacteria, viruses, fungi, and toxins produced by these microorganisms.

Some examples include:

• anthrax
• plague
• smallpox
• botulinum toxin
• tularemia
• ebola virus.

It is important to note that the use of any of these agents in a bioterrorism attack would have severe consequences and is considered a grave threat to public health and national security.

Detection and Identification of Biological Warfare Agents

Several methods can be used to detect and/or identify biological warfare agents, including:

“Detection of biological warfare agents is challenging due to the wide variety of pathogens that can be used as weapons and the difficulty in distinguishing between natural outbreaks and deliberate attacks”

Pitt, L.

Sampling and laboratory analysis

Samples of air, water, soil, tissue or other materials can be collected and analyzed in a laboratory to identify the presence of biological agents.

This can be done using techniques such as PCR (polymerase chain reaction), which amplifies small amounts of DNA or RNA to make it easier to detect, or ELISA (enzyme-linked immunosorbent assay), which uses antibodies to detect the presence of specific proteins or antigens.

Biosensors

Devices that can detect the presence of biological agents in real time. Some biosensors use genetic material from the agent to detect its presence, while others use antibodies or other proteins to identify specific agents. Such are antibody-based sticks or hand-held assays (HHA).

Physical and chemical methods

They detect the presence of biological agents without the need for laboratory analysis (which still would be needed for identification).

For example, biological agents can often be detected using ultraviolet light, because they fluoresce or emit light when exposed to UV light.

Specific ATP bioluminescence is one such non-specific detection method.

Other physical and chemical methods include:

• Colourimetric assays, which use a chemical reaction to change the colour of a solution in the presence of a biological agent.
• Mass spectrometry, which can identify the presence of specific biological molecules based on their mass
• Raman spectroscopy, or aerosol bio detector using fluorescence

It is worth noting that detecting biological warfare agents can be challenging, as many agents are difficult to detect due to their small size or their presence in low concentrations.

In addition, some agents are difficult to distinguish from naturally occurring organisms or toxins, which can make detection more challenging.

Other problems in biodetection and identification come from the complexity of bio agents (compared to chemical agents), mutations that can dramatically change virulence and unknown or new bio agents.

Protection against Biological Warfare Agents

“Effective protection against biological warfare agents requires a combination of vaccination, prophylactic drugs, and decontamination measures”

Alibek, K.

Several measures can be taken to protect against biological warfare agents, including:

Personal protective equipment (PPE)

This includes clothing and equipment that can help to protect the skin, eyes, an respiratory system from exposure to biological agents. Examples of PPE include gloves, goggles, masks, and suits.

Immunizations

Some biological agents can be prevented or treated with vaccines and/or serums. For example, vaccines are available for smallpox, anthrax, and some types of influenza.

Antiviral medications

These drugs can be used to treat viral infections caused by biological agents. For example, antiviral medications can be used to treat Ebola and some types of influenza.

Antibiotics

These drugs can be used to treat bacterial infections caused by biological agents. For example, antibiotics can be used to treat anthrax and plague.

Decontamination of Biological Warfare Agents

After exposure to a biological agent, it is important to decontaminate any affected areas or objects to prevent further exposure. This can be done using a variety of methods including:

• washing with soap and water
• using disinfectants
• heating to high temperatures.

It is worth noting that the effectiveness of these measures depends on the specific biological agent and the circumstances of the exposure. Some agents may not be preventable with vaccines or treatable with medications, and some decontamination protocols may not be fully effective against all agents.

Which Biological Agent Inspires the most Fear?

It is difficult to say which biological agent inspires the most fear, as people’s perceptions of what is most frightening can vary widely.

Some people may be more afraid of infectious diseases that are highly contagious and can spread rapidly, while others may be more afraid of diseases that have high mortality rates or that have no known cure.

Additionally, people may be more afraid of biological agents that have been used in the past as weapons of warfare or terrorism, or that have been depicted in popular media.

Some examples of biological agents that have inspired fear in the past include:

Smallpox

Smallpox is a highly contagious and often deadly infectious disease caused by the variola virus. It was responsible for countless epidemics and is estimated to have killed 300-500 million people in the recent centuries alone.

Smallpox has been used in the past as a biological weapon, and the fear of a smallpox outbreak has been used as a justification for vaccination campaigns and other public health measures.

Smallpox has been eradicated globally through a successful vaccination campaign, and the last naturally occurring case was reported in 1977.

Anthrax

Anthrax is an infectious disease caused by the bacterium Bacillus anthracis. It can be contracted through contact with infected animals, or through inhalation or ingestion of spores.

Anthrax can be used as a biological weapon and has been used in the past for this purpose. The fear of anthrax as a biological weapon has been fueled in part by a series of anthrax attacks that occurred in the United States in 2001, in which envelopes containing anthrax spores were mailed to various individuals.

Important Things to Know about Biological Warfare Agents

1. Biological warfare agents are living organisms or toxins that can be used to harm or kill people, animals, or plants. These agents include bacteria, viruses, fungi, and toxins produced by living organisms.
2. Biological warfare agents can be transmitted through the air, water, food, via other vectors or they can be delivered directly to the body through skin contact or injection. Some agents can survive for long periods in the environment and can be resistant to some disinfectants and other decontamination methods.
3. The symptoms of illness caused by biological warfare agents may not appear for days or weeks after exposure, making it difficult to identify the source of the infection.
4. There are limited treatments available for many biological warfare agents, and some agents have no known treatment.
5. Biological warfare agents have been used throughout history and are considered a major threat to national and international security. The use of biological warfare agents is prohibited by international law, as outlined in the Biological Weapons Convention.
6. It is important to be aware of the risks associated with biological warfare agents and to take appropriate precautions to protect against exposure. This may include using personal protective equipment, getting vaccinated, and practicing good hygiene.

Symptoms of Biological Warfare Agents Attack

The symptoms of illness caused by biological warfare agents can vary depending on the type of agent, the dose, and the route of exposure.

Some common symptoms may include:

1. Fever
2. Fatigue
3. Nausea and vomiting
4. Diarrhea
5. Abdominal pain
6. Chest pain
7. Difficulty breathing
8. Rash or skin irritation
9. Headache
10. Muscle and joint aches

It is important to note that the symptoms of illness caused by biological warfare agents may not appear for days or weeks after exposure, making it difficult to identify the source of the infection.

In some cases, the symptoms may be similar to those of a common cold or the flu, making it even more difficult to diagnose.

It is important to seek medical attention if you suspect that you have been exposed to a biological warfare agent.

What to do in Case of a Biological Warfare Agents’ Terrorist Attack?

In the event of a biological warfare agent’s terrorist attack, it is important to follow the instructions of local authorities and emergency responders. They will provide information on the specific steps to take to protect yourself and your family. Here are some general guidelines to follow:

1. Stay calm: It is important to stay as calm as possible and not panic. This will help you think clearly and make informed decisions.
2. Follow instructions: Local authorities and emergency responders will provide information on the specific steps to take to protect yourself and your family. Follow their instructions carefully.
3. Seek shelter: If you are advised to do so, seek shelter in a secure location. Close all windows and doors and turn off ventilation systems to prevent the spread of the agent.
4. Protect yourself: If you are advised to do so, wear a mask or other personal protective equipment to protect yourself from inhaling the agent. Practice good hygiene by washing your hands frequently with soap and water and/or skin disinfectant.
5. Stay informed: Keep an eye on the news and follow the instructions of local authorities and emergency responders. They will provide updates on the situation and any further steps you should take.

It is also important to be prepared in advance for the possibility of a biological warfare agent’s terrorist attack. This may include keeping a supply of water, non-perishable food, and personal protective equipment on hand in case of an emergency.

“The use of chemical weapons is a grave violation of international law and a threat to international peace and security. The consequences of their use are devastating and long-lasting, both for the individuals directly affected and for the broader community.”

The Organization for the Prohibition of Chemical Weapons (OPCW)

Generally, international treaties, including the most stringent Chemical Weapons Convention (CWC), prohibit the use, possession, development, production, acquiring, stockpiling, or retaining of chemical weapons or chemical warfare agents.

Also, even before the CWC, national governments strictly controlled their development, and now, national legislation restricts the usage of these chemicals (particularly ones belonging to the Schedules of the CWC) only for some controlled peaceful purposes.

What are the Chemical Warfare Agents (CWA)

A Chemical weapon, or CW, is a type of Weapons of Mass Destruction known, among else, for its brutality. Relatively, it is cheap and easy to produce, making it a potential threat even from small terrorist groups. Chemical weapon involves the use of toxic chemicals to harm or kill individuals.

“Chemical warfare is a particularly brutal form of aggression, in which innocent civilians, including women and children, suffer the most. Its effects can last long after the conflict ends, causing physical and psychological harm to survivors and future generations.”

International Committee of the Red Cross

Toxic chemicals that are specifically designed to be used as CW, and do not have almost any other purpose, are mostly defined as Chemical Warfare Agents  (CWA) and belong to Schedule 1 of the CWC.

These chemicals can be dispersed through various ways, such as:

• Spraying them from aircraft.
• Delivering them through missiles, artillery shells, bombs, or other munition types.
• Dispersing/Releasing them into the water supply as part of terrorist activity.
• Other dispersal ways.

Chemical warfare agents can affect the body in a variety of ways, from skin irritation,  causing respiratory problems, blindness, and other tissue and organs failures to cancer or lethal outcomes.

One of the major concerns with chemical warfare agents is that they are relatively cheap and easy to produce in comparison to other WMDs. This means that even small, non-state groups can potentially obtain and use some of these agents, making them a significant threat to global security.

Key aspects of the countermeasures to any usage of CWA are covered through Protection, Detection & Identification, and Decontamination.

Protection against chemical attacks

1- Physical protection methods

They include wearing protective clothing and using respiratory protection equipment.

2- Medical countermeasures methods

They involve administering treatments, such as antidotes, to counteract the effects of the chemical warfare agents exposure.

Detection Equipment

It is an important aspect of responding to chemical attacks. This can include devices that can detect and/or identify the presence of specific chemical agent(s) in the air, liquids/solids or on surfaces.

Decontamination Techniques

Decontamination protocols are used to remove or neutralize chemical agents from surfaces (e.g. people’s skin, equipment, objects, and the environment). This can involve, among others, washing, using special chemical decontamination solutions/emulsions/foams, or thermal destruction of the chemicals.

The History of Use of Chemical Warfare Agents

The use of toxic chemicals has a long and tragic history, dating back to ancient times. The Geneva Protocol of 1925 was the first international treaty to prohibit the use of chemical and biological weapons, but it had certain shortcomings and was not effectively enforced, and chemical weapons continued to be used in conflicts around the world.

“The use of chemical weapons is a clear breach of international law and a crime against humanity. The consequences of such actions are devastating and long-lasting, both for the individuals directly affected and for the broader community.”

United Nations Office for Disarmament Affairs

The use of chemical warfare agents dates back to ancient times when toxic substances were used in battle.

In the Middle Ages, various toxic substances, including arsenic and other poison smokes, were also used in warfare.

Regretfully, the use of chemical warfare agents was not restricted to ancient and medieval times. These weapons have been used throughout history and continued to be used in Modern Era.

“The use of chemical weapons is abhorrent and has severe consequences for the victims, their families, and the broader community. These weapons cause unspeakable suffering and death, and their use is a clear violation of international law.”

Amnesty International

During the early modern era, the use of chemical warfare agents continued to be a part of warfare. In the 17th and 18th centuries, various toxic substances were used in conflicts around the world, including poisonous smokes and other chemicals.

The Chemical Weapons Convention (1997)

It is the current international treaty that prohibits the use, possession, development, production, acquiring, stockpiling, or retaining of chemical weapons. It has been signed by most countries (but 5) and has resulted in the destruction of the majority of the world’s declared chemical weapons stockpiles.

However, the use of chemical weapons has continued to occur in some conflicts, despite the treaty. The most notable recent examples are the use of chemical weapons in the Syrian Civil War, anthrax letters, VX assassination, Skripal case, Navalny case, usage of CW in Iraq-Iran war (not in chronological order). The international community has condemned the use of chemical weapons in this conflicts/events and has taken steps to hold those responsible accountable.

Historical Events where CWAs were used

Ancient times

Toxic substances such as arsenic and other poisonous smokes were used in warfare.

World War I

Chemical warfare became more widespread in World War I, with the use of poison gases such as chlorine and mustard gas. These weapons were used by both sides in the conflict and resulted in significant casualties.

Events after World War I

By the time World War I ended, the world had been introduced to chemical warfare on an unprecedented level. While some groups thought that humanity had learned a lesson about the cruel nature of chemical war- fare, others prudently went to work on improving chemical defenses (Vedder and Walton, 1925). The thoughts of many professional military officers were that future wars would be fought under the new paradigm of chemical warfare (Vedder and Walton, 1925; Vedder, 1926; Smart, 1997). New gas masks were developed, and training in chemical environments was introduced (Vedder and Walton, 1925; Vedder, 1926; Joy, 1997).

Handbook of Toxicology of Chemical Warfare Agents
edited by Ramesh C. Gupta

World War II

Chemical weapons were again used in World War II, but in a more limited scope and not by most.  One of the most infamous example is the use of poison gas by the Japanese in their invasion of China, including the infamous attack on the Chinese city of Changed, where mustard gas was used.

“The use of chemical warfare in World War II was a horrific and deadly aspect of the conflict. It caused suffering and death on a massive scale, and its effects were felt long after the war ended. The use of these weapons is a clear violation of international law and a crime against humanity.”

United States Holocaust Memorial Museum

“The use of chemical weapons in World War I and II had a profound impact on the way in which warfare is perceived and conducted. It led to the development of international treaties and conventions to prevent their use in future conflicts.”

Mark Wheelis, researcher at the University of California, Davis

Iran-Iraq War

During the 1980s, both Iran and Iraq used chemical weapons against each other and their civilian populations. Iraq, in particular, used chemical weapons extensively against Iran and its Kurdish population.

Syrian Civil War

The use of chemical weapons has been a particularly controversial aspect of the Syrian Civil War. There have been numerous allegations of the use of chemical weapons by the Syrian government and its allies, as well as by non-state actors such as ISIS. The international community has condemned the use of chemical weapons in this conflict and has taken steps to hold those responsible accountable.

Types of Chemical Warfare Agents

Chemical warfare agents are substances used in military operations to harm or incapacitate people. CWAs are classified, by their mechanism of action, into the following main categories; nerve agents, blister agents, choking agents, blood agents, incapacitating, and riot-control agents.

In general, chemical warfare agents can be extremely hazardous and can cause extensive damage to people and the environment.

The use of chemical weapons is a violation of international law and a crime against humanity. The consequences of their use are devastating and long-lasting, causing suffering and death to innocent civilians.”

Ban Ki-moon, former Secretary-General of the United Nations

1. Nerve Agents

Nerve agents are highly toxic chemicals that disrupt the transmission of nerve impulses in the body. They are often odourless and tasteless and can be absorbed through the skin, inhaled, or ingested.

“Nerve agents are the most toxic and rapidly acting of the known chemical warfare agents. They are organic phosphorous compounds that interfere with the transmission of nerve impulses in the body, causing loss of muscle control, respiratory failure, and death.”

World Health Organization

Nerve agents include chemicals such as:

1. Sarin.
2. VX.
3. Soman.

Nerve agents mostly belong to a class of chemicals known as organophosphates, which inhibit the action of an enzyme called acetylcholinesterase. This enzyme is responsible for breaking down acetylcholine, a neurotransmitter that is involved in the transmission of nerve impulses.

When nerve agents inhibit the action of acetylcholinesterase, acetylcholine accumulates in the body, leading to overstimulation of the nerves and muscles.

The effects of nerve agents depend, among others, on the dose and the route of exposure.

Low doses of nerve agents can cause symptoms such as:

• Headache,
• Dizziness,
• Nausea, and vomiting.

Higher doses can cause more severe symptoms such as:

• Difficulty breathing,
• Muscle spasms,
• and paralysis.

In extreme doses, nerve agents can be deadly.

There are several specific antidotes for nerve agent poisoning, and additional supportive treatments including:

• Atropine, a medication that blocks the effects of acetylcholine to treat symptoms such as difficulty breathing and muscle spasms.
• Oximes reactivate acetylcholinesterase by removing the phosphoryl group
• Benzodiazepines, a class of sedative medications, treat seizures and other CNS effects.
• Oxygen therapy helps with breathing.
• Also, there are other medications may be given to support blood pressure and other vital functions.

2. Blister Agents

Blister agents, also known as vesicants, are chemicals that act through disrupting the cellular walls, damaging DNA and other cellular components, and causing severe skin irritation and blistering. They can be inhaled or absorbed through the skin.

“Blister agents, also known as vesicants, are chemicals that cause severe skin, eye, and mucosal irritation and damage. They can also damage the respiratory tract and other internal organs. Blister agents are usually liquids that can evaporate into a vapor (gas) and spread easily in the air. Examples of blister agents include sulfur mustard, nitrogen mustard, and lewisite.”

National Institute of Environmental Health Sciences

Examples of blister agents include:

1. Sulfur Mustard (Mustard Gas)
2. Lewisite.

They belong to a class of chemicals known as alkylating agents. When the skin is exposed to a blister agent, the chemical reacts with the skin cells, leading to inflammation and the formation of blisters.

The effects of blister agents depend, among else, on the dose and the route of exposure:

• Low doses of blister agents can cause symptoms such as skin irritation and redness.
• Higher doses can cause more severe symptoms such as blistering, ulceration, and scarring.
• In extreme doses, blister agents can be deadly.

There is no specific antidote for blister agent poisoning, and treatment is largely supportive:

• Decontamination of the affected area is important to prevent further absorption of the chemical.
• Topical medications and dressings are used to treat the skin irritation and blistering.
• Pain medications may be given for pain and discomfort.
• In severe cases, hospitalization may be necessary for further treatment and monitoring.
• Long-term cancerogenic effects also might need to be monitored/treated.

3. Blood Agents

Blood agents are chemicals that interfere with the body’s ability to utilize oxygen, leading to suffocation. They mostly cause a toxic effect through inhalation.

“Blood agents have been used as weapons of war and terrorism in several conflicts, including World War I and the Iran-Iraq War. They have also been used in terrorist attacks…”

Centers for Disease Control and Prevention

Examples of blood agents include:

1. Hydrogen Cyanide
2. Chloro cyanide.

They work by inhibiting the action of enzymes that are involved in the transport of oxygen in the body by red blood cells. When the body is exposed to a blood agent, the chemical reacts with the enzymes, disrupting the normal process of oxygen utilization and leading to a deficiency of oxygen in the body.

The effects of blood agents depend, mostly, on the dose:

• Low doses of blood agents can cause symptoms such as headache, dizziness, and nausea.
• Higher doses can cause more severe symptoms such as convulsions, loss of consciousness, and death.

There is no specific antidote for blood agent poisoning, and treatment is largely supportive:

• Decontamination of the affected area is important to prevent further absorption of the chemical.
• Oxygen therapy is often used to help restore oxygen levels in the body.
• Medications may be given to support vital functions.
• In severe cases, hospitalization may be necessary for further treatment and monitoring.

4. Choking agents

Choking agents are chemicals that cause inflammation and swelling of the mucous membranes in the respiratory system, leading to difficulty breathing.  They mostly cause toxic effect through inhalation.

Examples of choking agents include:

• Phosgene.
• Chloropicrin.

When the body is exposed to a choking agent, the chemical reacts with the cells in the respiratory tract, causing swelling and narrowing of the airways.

OPCW (Organization for the Prohibition of Chemical Weapons) defines choking agents as follows:

Agents inflicting injury mainly on the respiratory tract, choking agents irritate the nose, throat, and especially the lungs. When inhaled, these agents cause alveoli, air sacs in the lungs, to secrete fluid, essentially drowning those affected 

The effects of choking agents depend mostly on the dose:

• Low doses of choking agents can cause symptoms such as coughing, difficulty breathing, and chest tightness.
• Higher doses can cause more severe symptoms such as pulmonary edema (fluid accumulation in the lungs), respiratory failure, and death.

There is no specific antidote for choking agent poisoning, and treatment is largely supportive:

• Decontamination of the affected area is important to prevent further absorption of the chemical.
• Oxygen therapy is often used to help restore oxygen levels in the body.
• Medications may be given to support other vital functions.
• In severe cases, hospitalization may be necessary for further treatment and monitoring.

5. Incapacitating agents

Incapacitating agents are chemicals that cause hallucinations, confusion, and other psychological effects, rendering individuals unable to function normally. They mostly cause intoxication through inhalation.

Examples of incapacitating agents include:

1. BZ
2. LSD.

They work by disrupting the normal functioning of the central nervous system (CNS) leading to a range of psychological and neurological effects.

The effects of incapacitating agents depend mostly on the dose :

• Low doses of incapacitating agents can cause symptoms such as hallucinations, confusion, and disorientation.
• Higher doses can cause more severe symptoms such as delirium, coma, and death.

There is no specific antidote for incapacitating agent poisoning, and treatment is largely supportive:

• Decontamination of the affected area is important to prevent further absorption of the chemical.
• Symptomatic treatment may be used to manage the psychological and neurological effects of the chemical.
• Medications may be given to support other vital functions.
• In severe cases, hospitalization may be necessary for further treatment and monitoring.

Important Things to Know about Chemical Warfare Agents (CWA)

There are several things that the public should know about chemical warfare agents to protect themselves in the event of an attack.

1. Chemical Warfare Agents can be lethal

Many chemical warfare agents are highly toxic and lethal even in small doses. So, be aware of the potential risks associated with these chemicals to take steps to protect yourself.

2. Chemical Warfare Agents can be difficult to detect

Many chemical warfare agents are odourless and tasteless, which can make them difficult to sense the release/exposure.

It is important to be aware of the potential signs of chemical warfare agent exposure, such as unusual odours (if any) or physical symptoms, and to seek shelter and medical attention if necessary.

3. Chemical Warfare Agents can be dispersed in a variety of ways

Chemical warfare agents can be dispersed through the air, in water, or by contact with contaminated surfaces, thus allowing different exposure pathways.

4. Chemical Warfare Agents can have long-term effects

Chemical warfare agents tend to have immediate effects. However, there is also a risk of long-term effects such as cancer and other health problems. Therefore, it’s important to seek medical attention if you suspect that you have been exposed to a chemical warfare agent.

5. International Law prohibited Chemical Warfare Agents

 Each individual needs to support efforts to prevent the use of these weapons and to hold those who use them accountable.

Symptoms of Chemical Warfare Agent’s Attack

“Symptoms of chemical warfare agents can range from mild to severe and can include respiratory problems, skin irritation, and vision problems. In severe cases, chemical warfare agents can cause death.”

(https://www.medicinenet.com/chemical_warfare_agents/article.htm)

The symptoms of exposure to chemical warfare agents can vary depending on the specific agent and the dose. However, some common symptoms that may be experienced include:

1. Difficulty breathing: Many chemical warfare agents can cause respiratory problems, leading to difficulty breathing, coughing, and chest tightness.
2. Skin irritation: Some chemical warfare agents, such as blister agents, can cause severe skin irritation and blistering.
3. Redness of the eyes: Some chemical warfare agents can cause redness and irritation of the eyes.
4. Nausea and vomiting: Some chemical warfare agents can cause nausea and vomiting.
5. Headache: Many chemical warfare agents can cause headache.
6. Dizziness: Some chemical warfare agents can cause dizziness and disorientation.
7. Convulsions: Some chemical warfare agents can cause seizures and other CNS effects.
8. Coma: In severe cases, chemical warfare agent poisoning can cause coma or even death.

Note that these symptoms can also be caused by other factors. Also, it is not always possible to determine the presence of a chemical warfare agent based on these symptoms alone. If you suspect that you have been exposed to a chemical warfare agent, seek medical attention as soon as possible.

What to Do in Case of a Chemical Warfare Agents’ Terrorist Attack

In the event of a chemical warfare agent terrorist attack, follow these steps to protect yourself:

1. Seek Shelter

If you are outdoors, seek shelter immediately. If you are indoors, close all windows and doors and turn off any air conditioning or ventilation systems to prevent the chemical from entering the building.

2. Remove Contaminated Clothing

Clothing that has been exposed to a chemical warfare agent can continue to release the chemical, even after the initial exposure.

3. Decontaminate

If you have been exposed to a chemical warfare agent, quickly decontaminate to prevent further absorption of the chemical. This can be done by washing the affected area with soap and water.

4. Seek Medical Attention

The symptoms of chemical warfare agent poisoning can be treated, but it is important to receive treatment as soon as possible to minimize the risk of long-term effects.

It is important to remain calm and follow the instructions of authorities in the event of a chemical warfare agent terrorist attack. Stay informed by listening to local news and following any evacuation or shelter-in-place orders that may be issued.

Academic Education and Practical Training

Academic education refers to the formal study of a subject in a classroom setting, typically at a college or university. It typically involves learning about the theories, concepts, and principles related to a subject through lectures, reading, and other forms of instruction.

On the other hand, practical training refers to hands-on learning and experience gained through the practical application of the skills and knowledge acquired through academic education or other means. Practical training often involves working on real-world projects or simulations that provide a more immersive learning experience and allow individuals to apply their knowledge in a practical setting.

In the context of CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive), both academic education and practical training are essential for professionals who work in this field. Academic education provides a foundation of knowledge about the various types of CBRNE threats, as well as the principles and theories related to detecting, mitigating, and responding to these threats. Practical training, on the other hand, allows individuals to apply this knowledge in simulated or real-world scenarios, developing the skills and expertise needed to effectively respond to CBRNE incidents.

Who are the world’s best providers of Academic Education and Practical Training for CBRNE responses

There are many organizations and institutions around the world that provide both academic education and practical training for CBRNE responses. Some of the leading providers include:
