Description:Evaluates the risks to human health and the environment posed by endrin, an organochlo-rine insecticide used since the 1950s to protect cotton, rice, sugar cane, maize, and other crops against a wide range of agricultural pests. Because of its high toxicity and persistence in the environment, endrin has been banned in many countries and severely restricted in others. Ingestion of contaminated food is the most important route of human exposure.
