This article presents the results of a study on the effects of Cenomanian water on the numerical and species composition of testate amoebae community in a light gray forest soil. It was shown that soil invertebrates can be used as bioindicators of the pollution of the environment. We investigated the effect of water Cenomanian Aptian-Cenomanian water-bearing complex in the community of testate amoebae in the laboratory. Cenomanian water were made at concentrations of 50, 100 and 200 g/kg dry soil as control was considered the site without any concentration. Pollution produced artificially Cenomanian water (Sredneuralskie field) having the following characteristics: the amount of salinity of 19.3 g/l, total hardness is 29.1 mg - EQ/dm3., chlorine has an index (11347,3-12431,3 g - EQ/dm3), sodium (6650,2-7400,3 g - EQ/dm3) calcium ions - (44,0-53.7 g - EQ/dm3) magnesium ions - (0,9-12,7 g - EQ/dm3), hydrogen carbonate ions present in the amount of 1,8-5,4 g - EQ/dm3. Calculation and analysis of invertebrate organisms was performed using the microscope BIOMED-2 at magnification ×160. Accounting testate amoebae was carried out by direct microscopy of soil suspensions. The greatest impact on the structure and strength of the community have an oil concentration of 200 g/kg. it Was found that testate amoebae of the genera Phryganella, Cryptodifflugia, Cyclopyxis, Nebela most resistant to Cenomanian waters, and testate amoebae of the genera Euglypha, Chlamydohprys, Centropyxis, Plagiopyxis less resistant to impact. Also the study showed a decrease in abundance and species diversity of testate amoebae communities in making various concentrations of Cenomanian water in the soil. Material for the study can be used for researchers, teachers and students specializing in the field of General ecology and environmental management.
