Title Evaluation of the exposure of workers to organochlorinated insecticides during use in agriculture
Original title Zjišt'ování expozice pracovníků při aplikaci insekticidních preparátů typu chlorovaných uhlovodíků v zemědělství [in Czech]
Bibliographic information Oct. 1974, Vol.26, No.9, p.339-343. Illus. 21 ref.
Abstract The authors measured dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) atmospheric concentrations during potato crop spraying operations in the open with these insecticides. TLVs (Soviet values: 0.1mg/m3 for DDT and 0.05mg/m3 for HCH) were only exceeded while the sprayer tank was being filled, an operation which required only a few minutes. On the other hand, during the spraying of cowsheds values of 1.8 times the TLV (for DDT) and 1.4 times (HCH) were determined occasionally, whereas average concentrations were below the TLV. Chlorinated hydrocarbon blood plasma levels doubled after exposure to hot aerosols, and these levels were significantly higher among subjects normally occupationally exposed, even when at rest, than among controls. The question of absorption of these insecticides in food is considered.
