USAGE OF THE BACTERIAL PREPARATION “DESTROIL” FOR DESTRUCTION OIL POLLUTION IN FRESH WATER
DescriptionThe researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined

COMPARATIVE ASSESSMENT OF FUNGICIDES OF NEW GENERATIONS TOXIC TO DAPHNIA
DescriptionWe have assessed the effect of the new generations of fungicides on the vital activity of daphnia. The data of the chronic experiment allowed us to determine non-effective and threshold concentrations of the substances studied. The toxic effect of the xenobiotics is shown to be of different intensity. When entering water they may be dangerous, first of all, for the zooplankton that is the food base of young fish, and may have unfavorable effects on fish development

Description
The article presents the results on the effects of Imazethapyr herbicide on aquatic organisms. The chronic toxic effects have been studied of the imidazolinone herbicide in a concentration range of 0.4 - 1150 mg/l to the representatives of various groups of aquatic organisms: zoobenthos – great ramshorn snail (Planorbarius corneus), zooplankton - Daphnia (Daphnia magna Straus), phytoplankton - protococcal alga (Scenedesmus guadrigauda) and macrophytes - higher aquatic vegetation (Elodea canadensis Michx). It is shown that the herbicide does not have a pronounced lethal effect to aquatic organisms tested. Their respective LC50 values are > 1000, 680, 510 and 910. Elodea is shown to be most sensitive to its sublethal effects (decreased growth of lateral and main sprouts at a concentration of 10 mg/l and more), reduced fertility was observed in Daphnia at a concentration of 300 mg/l and above, and as to the great ramshorn snail no sublethal effects have been revealed for all the concentrations studied
