Studies on exposure during the use of anticholinesterase pesticides.

Relatively few studies have been made of the exposure of workers to pesticides. Of these, approximately half involved chlorinated hydrocarbon insecticides, and most involved agricultural applications. Some important matters, especially indoor spraying-e.g., for malaria control-have been investigated experimentally with DDT only. Fortunately, information on exposure during agricultural use-which is of considerable interest in itself-can serve as a rough guide in connexion with the exposures associated with vector-control activities. This paper reviews the different methods of measuring exposure and the significance of some of the results that have been obtained.
