Ecotoxicological evaluation of urban soils and detoxication effect of nanocomposite preparation
The ecological quality of some urban soils being under the constant influence of aerotechnogenic pollution of Kirov industrial district has been study. Close correlation between content of heavy metals Pb, Ni, Cr Cd (Zc ) and the response of the biotest-systems has been established. The sensitivity of the biotests by heavy metals pollution evolved within decrease in row the bioluminescence bacteria Escherichia coli > crustaceans Daphnia magna > higher plant Sinapis alba > algae Scenedesmus quadricauda > infusoriance Paramecium caudatum. The simulation of soil remediation has showed that the detoxifing effects of the modern nanocomposite preparation and the commercial humate (Humi-90) are similar.
