Cytotoxicity estimation of drilling slime samples, collected in the territory of barn, in nature of Khanty-Mansi autonomous district-Ugra

Placement in objects of environment the waste of drilling, containing heavy metals and other toxic substances, are the main source of negative ecotoxic impact of quality on ecosystems in areas of conducting drilling operations. In work by biotesting method with use of infusorians Parameciumcaudatum the assessment of slime samples cytotoxicity, collected in the territory, is carried out. The conclusion about high degree of heterogeneity of toxicity degree, both on depths and on the area of a barn is made. The received results don't allow to estimate a total contribution of each defined component to the general toxicity of test.
