Abstract:
Application of pesticides in modern agriculture is a powerful permanent risk factor for public health and the natural environment. The aim of the study was a comparative hygienic assessment of the danger of contamination of ground and surface water sources with most widely used herbicides of different chemical classes (sulfonylureas, imidazolinones, pirimidinilkarboksilovye compounds semicarbazones). Field hygienic experiments for studying of the residues dynamics of studied herbicides concentration in agrocenosis objects were made by us in different types of soils: chernozem, sod-podzolic, podzolized forest. Then the half-life periods (DT50) of the substances in the soil were calculated. It was found that according to GUS index there is a high probability of leaching into groundwater of sulfonylureas and imidazolinones; according to LEACH index all investigated substances have a high risk of run-off into groundwater and surface water.
