Blood levels of organochlorine pesticides in Argentina: Occupationally and nonoccupationally exposed adults, children and newborn infants☆

摘要: Abstract Determination of the concentration organochlorine pesticides has been made in adults, children, newborn infants, and various groups occupationally exposed individuals Argentina. β-HCH levels adults Argentina are approximately 16 times higher, on average, than found U.S. In contrast, concentrations p,p′ -DDE, dieldrin, -DDT closely similar to those Concentrations children lower, but still higher U.S., much children. Pesticide workers handling HCH were extremely high, as DDT isomers this pesticide. No dieldrin was detected these workers—a possible indication that microsomal stimulation by may have responsible for clearing tissues. The DDE:DDT ratio appeared be an accurate measurement a recent exposure DDT. Pesticides passed placental barrier, transmission apparently somewhat retarded. -DDT, 40% pesticide blood mother. This percentage α-HCH, lindane.
