We 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
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
