In the raport results of one-year research on determination of the pollution level by insecticides in pollen and the examination of their decay dynamics in pollen are presented. The experiments were conducted on winter raps with the usage of such preparations as: Thiodan, Metox, Sadofos, Zolone, Cymbusz and Decis. It was pointed out that applisd preparations in appreciable degree penetrated into pollen, their amounts depended on dose of the insecticide. The dissapperance rates were differentiated and relatively fast. In laboratory conditions the insecticides residues in pollen dissappeared much slower.
