Question

cullert. 5. The G-series nerve agents are based on the chemical properties of what common chemical(s)? Discuss the mode of action of the nerve agents in general. 7. Does the dose rate of a nerve agent affect the body's response? Explain. What is the effect of daily exposure to small doses of a nerve agent over several days? 3. Explain "persistence" of a chemical weapons agent, in terms of its reactions with air, microorganisms, sunlight, and so on. Which

Answer 1

Nerve agents are organophosphorus (OP) compounds that inhibit acetylcholinesterase (AChE) extremely rapidly, which results in an accumulation of acetylcholine (ACh), leads to muscle fasciculations and paralysis, and finally results in death

G-series nerve agents share a number of common physical and chemical properties. The organophosphate nerve agents tabun (GA), sarin (GB), soman (GD), and cyclosarin (GF) are among the most toxic chemical agents .Together they comprise the G-series nerve agents, thus named because German scientists first synthesized them,The only other known nerve agent, O-ethyl S-(2-diisopropylaminoethyl) methylphosphonothioate (VX)

2) yes the dose of nerve agent affect the body  response.Initial symptoms following exposure tonerve agents (like sarin) are a runny nose, tightness in the chest, and constriction of the pupils. Soon after, the victim will have difficulty breathing and will experience nausea and salivation. ... The effects of nerve agents are long lasting and increase with continued exposure.Nerve agents block normal functioning of these chemicals at nerve endings. The nerve then sends too many signals. This constant signaling of the nerve can cause overload in parts of the body.

3) Chemical warfare agents fall into four major classes: nerve, blister, choking, and bloodagents.

persitence chemical weapon agents are the weapons which will not readily volatize or be decomposed by chemical reactions or biological processes. thus these persistant chemical weapons can not be destroyed easily. the air, sunlight microbial activity can not stop or resist the chemical weapon impacts. thus persistant chemical weapons are threat from terrorist activity.
