The storage of insecticides in the body-fat of persons has previously been studied in several countries (e.g., England, France, USA) and food has been shown to be the main source from which DDT and perhaps other insecticides are absorbed. In view of the differences in dietary habits in India, a study was made to determine whether there are differences in the storage of chlorinated hydrocarbon insecticides in persons in India from that in persons in other countries. It was found that civilians in the Delhi area with no occupational exposure to insecticides had a significantly greater deposit in their fat of DDT-related compounds and HCH than do comparable persons in the USA, but less dieldrin and heptachlor epoxide. Storage in military personnel in other Indian cities from which samples were obtained was similar to that in the USA for most DDT-related compounds and HCH but, as in Delhi, lower for dieldrin and heptachlor epoxide.
