Abstract
In this study, amphipods Eulimnogammarus vittatus were evaluated as test organisms for use in aquatic toxicity bioassays. Dependence of the time of departure of organisms from the light on presence of toxicants was studied. The most rapid response to light was established in pure Baikal water. Presence of pollutants retarded moving of E. vittatus individuals to the dark areas. A similar effect was observed in the experiments with heavy metals, detergents, and petroleum products. The results obtained indicate good prospects of using this test reaction of E. vittatus as a biological assay for toxic contamination.
