The occurrence and leaching of some widely used pesticides were studied in 1985–1987 in an experiitiental field, in a small agricultural drainage basin and in a river highly loaded by agriculture. Phenoxy herbicides were found in most of the samples and the highest concentrations were measured in πddsummer, soon after the application. High concentrations were usually associated with heavy rainfall events. Trace amounts of some highly toxic insecticides could also be detected in the same samples.
