Abstract
Tests were made of the blood of individuals occupationally exposed to organochlorine pesticides and members of the general population of Argentina in order to determine the degree to which the general population has been exposed to such chemicals. Individuals who have been engaged during at least 5 years in the application of these pesticides in the antimalaria and Chagas disease campaigns had much higher levels of these chemicals in their blood samples. Even so, none of these individuals demonstrated any excess of clinical signs of toxicity, carcinogenesis, or absence from work. Tests made of infants indicated that babies were born with a detectable amount of these chemicals in their blood stream. This amount increases during the first 5 to 7 years of life, and then levels off. Newborns had a concentration of these pesticides in the blood which was 20 to 50 times less than that of their mothers, due in part to the smaller amount of fatty tissue present in the body of the newborn and secondly to the detoxicating properties of the placenta. Samples of uncooked food had levels of DDT (50293), dieldrin (60571) and lindane (58899) which were all below the accepted standards for daily intake. At times there were levels of alpha-BHC (319846) or beta-BHC (319857) which even surpassed the quantities of the active pesticide present. The author indicated that the concentration of chlorinated residues in the milk of mothers was such that breast feeding may pass dangerously high levels on to the suckling child.
