Biotesting of Water Bodies in Metropolitan Areas

Environmental monitoring of natural objects invariably remains a necessary and real reflection of the pollution level under the anthropogenic influence. This work contains a study of surface waters to determine their toxicity using biotesting, which allows to assess the quality of fishery water resources. The rivers of the Moscow city and the Krasnoyarsk city were chosen as the objects of the study. Chlorella vulgaris Beijer served as a test object for assessing the toxicity of waters. The study was conducted using photometry. Based on the results obtained, it is proposed to provide measures to reduce the recreational load and systematic quality control of rivers.
