This work was aimed at studying the laws of accumulation of elemental toxicants by various morphological parts of the linden plant using inductively coupled plasma (ICP) mass spectrometry taking into account the anthropogenic influence of the environment. The total indicators of chemical pollution at 22 collection sites were calculated for various morphological parts of linden and used to assign the associated soils to different pollution hazard categories. The coefficients of elemental toxicant (ET) accumulation by the morphological parts of linden were calculated for each soil category relative to the content of bioavailable ET forms in the associated soils. On this basis, differences in the ability to accumulate ETs (V, Cr, Mn, Co, Ni, Cu, Zn, As, Sr, Mo, Cd, Ba, Pb, and Hg) for linden leaves and flowers were established. Spearman’s nonparametric correlation coefficients were calculated between the ET content in the plant and soil for each element. The source of elemental toxicant contamination was determined for linden leaves and flowers based on a comparison of the accumulation and correlation coefficients.
