Dichlorvos

Abstract

Dichlorvos is a contact and stomach insecticide used worldwide to control insects on crops and domestic animals. The compound is also used as an insecticide in houses and other buildings and for insect control in aircraft. This book evaluates the effects on man and the environment associated with the widespread use of dichlorvos. Noting that exposure via contaminated food and drinking-water is negligible, the book concentrates on health risks in occupational conditions and among residents in houses or buildings using dichlorvos as an insecticide, primarily in the form of sprays or slow-release strips. Risks to animal species and man are evaluated on the basis of extensive research conducted in experimental animals and in vitro test systems. Concerning environmental hazards, the book concludes that, with the exception of conditions caused by gross spillage, the recommended use of dichlorvos as an insecticide does not constitute an acute or long-term hazard for aquatic or terrestrial organisms. The high toxicity for birds and bees necessitates caution in the use and handling of dichlorvos where these species might be exposed
