Abstract
The use of an electron capture detector for the determination of chlorinated insecticide residues in water is described. A linear response of the detector was found for BHC and DDT isomers and metabolites in the range 0.03–1.20 μg/ml. Results for the determination of chlorinated insecticide (γ-BHC; α- + β- + δ-BHC; DDT + DDE) residues in waters in Slovakia (for the years 1971–72) are given. BHC and DDT contents in Slovakian rivers ranging from 0.01 to 0.80 μg/l, in the Danube from 0.01 to 0.60 μg/l and in ground waters from 0.02 to 0.30 μg/l were found. The DDT content was lower than the content of BHC residues. The results agree well with the actual consumption of chlorinated insecticides in agriculture in the area studied.
