Abstract:

The main objective of researches is the definition of the ecological status of water bodies of the Salgir River using bioassay technique. The main goal is to define the feasibility of using these waters for irrigation. For this purpose the base alignments were chosen on the river, exposed on different intensity of anthropogenic loads, and also the treated wastewater from sewerage facilities of Simferopol. The bioassay technique presented growing seeds of test plants in the studied waters and following comparison of the length of their root system with the same seedlings grown in the distilled water. Garden radish and garden cress seeds were chosen as test plants seeds. The phytotoxicity of the tested waters was shown in inhibition of the root system development of test plants. The root system in contact with the studied waters has been developing more slowly, what proves the presence of harmful substances in testing waters, and shows their toxic effect on the plants developing. The biggest sensitivity to pollutants showed the garden cress, which had the maximal inhibiting effect of roots development of 41.8%, in comparison to the monitoring in distilled water. The experiment showed the prospects of use of test plants, with their short-term exposure with the studied waters, as a reflective criterion for bioassay testing of pollution of the natural and treated sewage waters.
