Abstract : The article presents a historical background on the use of tear gases in war and civilian riot control activity. The classification of chemical compounds used as irritants, and their structure-activity relationship established through different studies has been examined. A review of toxic effects which is different from irritancy of Adamsite, omega-chloroacetophenorie(CN), o-chlorobenzylidene malononitrile (CS) and Dibenz (b,f),[1,4}-oxazepine(CR) has been presented.

Abstract : Bis (2-chloroethyl) sulphide commonly known as sulphur mustard (SM) is highly reactive bifunctional compound, documented as antimitotic, mutagenic, carcinogenic, teratogenic and cytotoxic agent. It is a powerful vesicant and has been employed as a chemical warfare agent. Skin, eyes and respiratory tract are the principal target organs and the deoxyribose nucleic acid (DNA) is the most important molecular target of SM toxicity. There is no specific antidote for SM injury .Treatment to SM toxicity is symptomatic.

Abstract : The efficacy of dibenz (b,f)-l ,4-oxazepine (CR), a potent sensory irritant and deltamethrin a well-known insecticide, in providing protection to the multi-element nylon tapes, used as aircraft arresters at airports have been evaluated. The results obtained indicate that 5 per cent CR-admixed UV resistant nylon tapes got adequate protection against attacks from wild type laboratory bred Rattus rattus for up to 160 days. CR treatment was found to be water wash resistant against 7, 30 and 60 days protection offered by 3, 4 and 5 per cent deltamethrin, respectively.
