Sažetak

In pot experiments in the open, without vegetation, the degradation and accumulation of prometrine (herbicide of the triazine group) in two different soil types, the rendzina and brown soil, were observed. Degradation of prometrine in the upper layer of rendzina (up to 5 cm) with pH = 7 and an average of 9-% humus was in the summer season by 4 times slower than on brown soil with pH = 5-6 and a lesser amount of humus (6%). More regular was migration to the lower layers (up to 15 cm). After six months, however, the relative degradation of prometrine in brown soil was in the upper layer slower. The presence of chlorinated pesticide residues in water was determined or fish samples, since these residues are especially accumulated in some parts of aquatic animals. By analyses of fish samples from the Slovenian coast of the Adriatic, the presence of DDT and its metabolites was established. In some instances also measurable quantities of dieldrin were found.
