The article describes the migration of chemical substances contained in bottom sediments of water bodies of the Nizhnevartovsk district. On the basis of chemical analysis of samples of bottom sediments of the Ob was carried out a statistical analysis of all studied parameters. The results of correlation analysis revealed significant positive and negative correlation between the chemical substances in the investigated bottom sediments. Regression analysis of toxicity of bottom sediments via biological and chemical indicators indicates a weak relationship chemical parameters of the studied samples and high regression dependence of the concentrations of chemicals between them.
