摘要

Urban water bodies are at high risk of anthropogenic pollution. The content of 5 macroelements (P, S, Cl, K, and Ca) and 17 microelements (Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Rb, Sr, Cd, Sn, Ba, Pb, and Hg) in the muscle tissue of the invasive fish rotan (Perccottus glenii) from 10 water bodies located in different districts of Moscow (Russia) was studied. In general, the level of elements content in the muscle tissue of rotan did not depend on the location of the water body: residential areas, areas near major roadways, or specially protected green areas. Correlations of the content of individual chemical elements with the sex and size of fish were revealed, as well as correlations of concentrations of individual elements among themselves. Concentrations of trace elements, regulated by the legislation of the Russian Federation (Pb, As, Cd, and Hg), as well as those recommended for monitoring (Cu, Zn), do not exceed permissible values, which indicates a relatively favorable condition of the studied water bodies in terms of pollution by chemical elements.
