✦ Synopsis

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-l -20 ,ug/ml. Results for the determination of chlorinated insecticide +BHC; a-+ p-+ 6-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 0.8O,ug/l, in the Danube from 0.01 to 0.60 ,ug/l and in ground waters from 0.02 to 0.30 ,ug/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.

## Abstract This paper describes the extraction of 20 organochlorine pesticides (OCPs) from water samples using solid‐phase microextraction (SPME). Three fused‐silica fibers coated or bonded with polydimethylsiloxane (PDMS) of different film thicknesses (20‐, 30‐, and 100‐μm) were evaluated. The ex
