In recent years, there has been considerable interest in the problem of medical treatment of and protection against poisoning by organophosphorus compounds: this class of chemicals includes many pesticides in widespread use in agriculture, as well as chemical-warfare nerve agents—the most lethal modern chemical weapons. Certain drugs can successfully counter some of the toxic effects of some organophosphorus compounds, but there are still some significant limitations in the therapeutic methods available today.
Continued research into this problem is important, not only in the context of pesticide poisoning, but also for developing effective means of protection against the possible use of organophosphorus nerve agents in war. This book, which is based on the proceedings of an international symposium attended by toxicologists, pharmacologists, biochemists and disarmament experts, describes the current status of medical protection against organophosphorus poisoning, reviews the current research efforts in this area, and assesses the possibilities of more effective treatment methods being developed in the future.
