Abstract

Immunotoxicologic effects have been reported for a number of pesticides. Since pesticides represent a large range of chemical classes, different types of chemicals may affect the complex immune system by a variety of mechanisms. A preliminary evaluation of pesticides for immunotoxicologic potential can best be incorporated in general subacute and chronic toxicity testing, with additional groups assigned for initial host-sensitivity assays. For chemicals that are possible candidates for immunotoxicity in preliminary assays, a comprehensive immunotoxicity screening has been suggested. Finally, emphasis should be given to mechanistic investigations to objectively assess the immunotoxicity of a new chemical and possible extrapolation to man. Animal models need to be developed for detecting the autoimmunologic potential of pesticides. This paper provides a brief listing of various approaches currently employed in the evaluation of immunotoxicity.
