The highest endrin residue in 15 forest soil samples was 0.2 ppm, which is nearly twice the amount of endrin sprayed on the area in one treatment. In6analysed garden soils the maximum residue was 0.13 ppm, which is equivalent to one treatment. In general, endrin had not significantly accumulated in these soils, even after many years of use. The endrin residues did not correlate with the quantities used or the type of soil. DDT or its metabolites were discovered only from two forest areas and one garden area. The highest residue was 0.02 ppm. PCB’s with low chlorine content (42 % of Cl) were not found, but a high-chlorinated compound (60 % of Cl) was discovered from six forest soils, the highest residue being 0.1 ppm
