System of the complex assessment indices of the urboecosystem soils contamination by the heavy metals
Journal Title: Екологічні науки - Year 2018, Vol 20, Issue 2
Abstract
The complex assessment system of the contamination by the heavy metals of the urboecosystem soils has been developed by using mathematical statistics methods to attract indicators that take into account the polyelemental nature of the artificially created geochemical anomaly, phytotoxicity and the level of the environmental risk. The expedient using of the phytotoxicity index has proved to the urboecosystem soils as a result of close back correlation and regression equations with respect to the imbalance coefficient. The degree of environmental hazard of the soil contamination by the heavy metals is recommended to be determined with the help of potential environmental risk, due to the presence of a close correlation with integrated indicators of the polyelemental contamination and regression equations with high reliability of approximation.
