ASSESSMENT OF SYNERGIC ACTION OF MODERN PESTICIDES FOUND IN THE WATER BODIES OF THE AZOV SEA BASIN ON COMMERCIAL FISH SPECIES AND THEIR FOOD BASE
Synergic action has been studied of the pesticides (imazalil, iprodione, tebuconazole and ethofumesate) found in the water bodies of the Azov Sea basin on phyto- and zooplankton, zoobenthos, sturgeons, gobies and Cyprinidae. These pesticides in the combination applied are shown to have a negative effect on some links of the trophic chain even if they are used in concentrations smaller than maximum admissible concentrations adopted for fishery waterbodies.
