The article presents the concentrations of ecotoxicants in the small Hodz river. The excess of the MPC for iron at all points and at all times of determination, an increase in the concentration of this element over time has been established. Based on the combinatorial index, a high level of water pollution is determined, due to the specificity of the natural background of iron.

Keywords:heavy metals, ecotoxicants, seasonal dynamics, natural background.
