The paper presents the results on the content of heavy metals in the bottom sediments of shallow areas of the Sheksninsky spur and the correlation dependences on the content of heavy metals. Significant differences in the content of heavy metals on different banks of the Sheksninsky spur were found only for lead (p=0.042). The matrices of paired correlations were constructed, the analysis of which showed that a greater number of dependencies with heavy metals were found on the right bank. The sorption of mercury by organic matter plays a greater role than the sorption of other elements, the correlation is significant r=0.70. Single exceedances of maximum permissible concentrations (MPC) of lead and copper in bottom sediments of the right bank were detected. Exceedances of element clarks determined for the earth crust were observed for lead, zinc, copper for bottom sediments of the right bank. A decreasing series of distribution of heavy metal concentrations in bottom sediments of the Sheksninsky spur was determined.
