Research and Development for Health and Environmental Hazard Problem Definition Study: Fate and Effects of Five Pesticides of Military Importance on Secondary Biological Wastewater Treatment Plants

摘要

This report reviews the literature pertaining to the fate and effects of five pesticides (Baygon, Chlordane, Diazinon, Dursban, and Malathion) introduced in dilute concentrations to secondary wastewater treatment plants. The review addresses the following subjects: the rates and products of biodegradation of the pesticides in both pure and mixed (from sources such as sewage, soils, ponds, etc.) microbial cultures; toxic or inhibitory levels of the pesticide which are disruptive to the ecology or operation of biological wastewater treatment plants; and chemical processes, such as hydrolysis, volatilization and adsorption which reduce the concentrations of the pesticide in the effluent. Literature citations were obtained by a computerized search of twenty data bases, communication with pesticide manufacturers, government agencies, and university researchers. A manual search of chemical abstracts was conducted for Baygon and Chlordane. The report contains a detailed description of the experimental conditions and results of each article pertaining to the biodegradation and effects of each pesticide.
