ASSESSMENT OF POLYELEMENT CONTAMINATION OF SOME TERRITORIES AND SUBSTRATES IN BREST REGION
The paper provides actual data on territories with environmental risks of trace element contamination in Brest region. 4 types of territories have been identified that require the ecological restaration. A selection of potential sites for phytoremediation was made. 17 territories and 2 technogenic substrates were investigated. A web application has been created to process and visualize the results. The selection of soil simples and substrates was carried out, lysimetric extracts were obtained, and their assessment was carried out by physicochemical and biotesting methods. Priority pollutant elements have been identified. A biotesting technique has been developed, scales of soil phytotoxicity have been compiled for the subsequent application of phytoremediation technologies.
