Male school children exposed to the pesticide endosulfan showed delayed sexual maturity compared with similar children who were not exposed, according to a study published today in the December issue of the peer-reviewed journal Environmental Health Perspectives (EHP). Endosulfan also appears to interfere with sex hormone synthesis, according to results of the study of males aged 10-19 years in a community of cashew plantations in northern Kerala, India. Although endosulfan is no longer made in the United States, an estimated 1.4-2.2 million pounds are used in the United States on crops including squash, pecans, and strawberries. EHP Press Release
