They likely did not realize that effects might be more serious under wartime conditions than in riot control.

Vijayaraghavan Find articles by R. The carbamylated enzyme hydrolyzes slowly with a half-life of about 30 minutes. Nerve agents such as sarin, soman, cyclohexylsarin, tabun, VX Vesicating or blistering agents such as mustards, lewisite Choking agents or lung toxicants such as chlorine, phosgene, diphosgene Cyanides Incapacitating agents such as anticholinergic compounds Lacrimating or riot control agents such as pepper gas, chloroacetophenone, CS Vomiting agents such as adamsite Physical properties: No doubt in time chemistry will be used to lessen the suffering of combatants, and even of criminals condemned to death.

Edema of the conjunctival and lids follow rapidly and close the eye within an hour. Prolonged wearing of individual protective equipment can lead to stress, fatigue, disorientation, confusion, frustration, and irritability.

For many chemical warfare agents, doctors can only treat the symptoms they produce. Nerve agents also act on the heart and may produce abnormal heartbeats, more likely to be too fast rather than slow. This is followed by severe generalised muscular weakness, including the muscles of respiration.

In the presence of nerve agent the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine, is inhibited.

Chemical warfare

Collective protective shelters, complete with filters for airflow systems, have been provided to shield personnel in an otherwise contaminated area. In cases of severe poisoning by nerve agents, large doses of atropine grammes may be required. Vapor exposure damages the upper respiratory tract skin usually is not affected.

Sulfur mustard is considered a persistent agent with low volatility at cool temperatures but becomes a major vapor hazard at high temperatures.

Filters for masks and shelters contain specially treated activated charcoal, to remove vapours, and paper membranes or other materials, to remove particles. In some casualties there is apathy, withdrawal and depression. Soman poisoning is complicated by the inhibited enzyme going through an "ageing" process.

Rarely, mustard damages rapidly growing cells of the intestinal tract. Under temperate conditions, all nerve agents are volatile liquids, which means they can evaporate quickly. Involuntary discharge of urine and defecation may also form part of the picture.

Types of Chemical Weapon Agents Chemical weapon agents are hazardous substances. Although their primary function was never abandoned, a variety of fills for shells were developed to maximize the effects of the smoke.Chemical detectors have been developed to help identify levels and places of contamination.

These include chemically treated litmus paper used to determine the presence of chemical agents. Other sensors may include handheld assays, vehicles equipped with. List of chemical warfare agents. Jump to navigation Jump to search. Part of a series on injure or incapacitate human beings.

About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century. These agents may be in liquid, gas or solid form. These are high volatility nerve agents that are.

CHEMICAL WARFARE The use of chemical agents in warfare goes back to ancient times. napalm and nerve agents. Chemical agents may be delivered by a variety of methods including bombs, spray tanks, rockets, missiles, land mines and artillery projectiles. delivery systems that can be used in different battle situations, plans for safely.

Generally considered the most deadly of the different categories of chemical weapons, nerve agents – in liquid or gas form - can be inhaled or absorbed through the skin.

Nerve agents inhibit the body’s respiratory and cardiovascular capability by causing severe damage to the central nervous system, and can result in death. with an overview of chemical warfare agents and analytical methods for their determination. Researchers interested in developing new methods for chemical warfare agents may use the reviewed material to quickly ascertain the state of development of analytical methods, in.

A Chemical Weapon is a chemical used to cause intentional death or harm through its toxic properties. Munitions, devices and other equipment specifically designed to weaponise toxic chemicals also fall under the definition of chemical weapons.
