PESTAB. Though not exhaustive, this review attempts to bring together much of the available comparative data on the amounts of residues in the environment, pointing out the largest residues and showing how they are concentrated from lower organisms into higher trophic levels of the food chain. Tables of data with references indicate DDT, aldrin, gamma-BHC, chlordane, dieldrin, endosulfan, endrin, heptachlor, heptachlor epoxide, camphechlor, isobenzan, methoxychlor, toxaphene, 2,4-D, 2,4,5-T , and 2,4,5-TP residues in soil, air and water. Extensive tables of occurrences and persistence are also given for pesticides in soil fauna and flora, aquatic invertebrates, fish and aquatic mammals, plants, birds, terrestrial mammals, food, feed, and man. One chapter reviews persistence of arsenicals, mercurials, and non-organochlorine herbicides, fungicides and insecticides. A chapter on minimizing pesticides in the environment includes brief discussions of carbamates and biodegradable organochlorine analogs, better use of pesticides, removal of pesticides, alternative methods of control, governmental establishment of tolerance limits, and recent legislation on the use of pesticides in various countries. Various compartmental models of pesticide movement in the environment are described.
