Chemical Agents Encountered in Protests

Emergency Medicine Clinics of North America, 2022
The most common chemicals used in riot control agents are chlorobenzylidene malononitrile, chloroacetophenone, dibenz[b,f]-[1,4]-oxazepine, and oleoresin capsicum. They cause ocular, respiratory, and dermal effects usually within seconds to minutes of exposure, but delayed effects have been reported.

Rejection and the use of chemical agents

Social Science & Medicine. Part E: Medical Psychology, 1981
Abstract The Avoidance of Rejection Scales (of self, by others and of others) were specifically developed to assist the psychometric documentation of choice of an avoidance versus confrontation strategy to the issue of rejection. Three kinds of rejection were examined concurrently with respect to the use of 7 chemical agents related to health and ...

Chemical carcinogenicity and the antineoplastic agents

American Journal of Health-System Pharmacy, 1984
The subject of chemical carcinogenicity is reviewed with discussions of the involved environmental factors, proposed mechanisms of mutagenesis and carcinogenesis, dose-response considerations, secondary tumor development, and an emphasis on the potential carcinogenicity of antineoplastic agents. Although the causes of various cancers are complex, 70-90%
