Chemical defense: history, warfare agent classification and action of neurotoxic agents

CHEMICAL DEFENSE: HISTORY, WARFARE AGENT CLASSIFICATION AND ACTION OF NEUROTOXIC AGENTS. Chemical agents are substances used for their toxic effects on humans, animals and plants. The main objective of chemical defense is to develop systems that reduce these effects while minimizing impact on the operational capacity of military troops. In this work, a report on the development of chemical warfare agents since the First World War and their classification is presented. Special attention is given to neurotoxic agents, the most lethal group of chemical agents known to date.
