Determination of soil toxicity man-made zones by example of city with developed industry

Abstract

Abstract The soils of the industrial city were investigated using phytotesting methods. Cress salad was chosen as the test object. Toxicity was assessed based on a comparison of germination and total seedling length. Based on the experiments conducted, one can judge the close relationship between atmospheric air pollution and depositing media - snow and soil cover. The main centers of contamination were identified, priority sources of pollution were established. It was established that the distribution of pollutants in the city is influenced by the physical and geographical characteristics of the area and meteorological conditions for the dispersion of pollutants.
