Abstract
The impact of the destruction of the Kakhovka HPP dam and longterm flooding on the ecological condition of agricultural lands is highlighted. The results of experimental studies of the content of mobile compounds of heavy metals in thirteen collective soil samples taken on the territory of Bereznehuvatе and Snihurivka TG of Bashtan district of Mykolaiv region are given.
According to the results of the conducted research, it was established that the maximum permissible concentration (MPC) of mobile compounds of heavy metals was exceeded only by the content of lead, which was noted in the soil of plot 6 on the territory of the village. Ternivka of Berezneguvatska TG of Bashtan district. Also, one site is characterized by a very high degree of pollution by mobile lead compounds, four sites by high and medium pollution, three sites by a moderate degree of pollution. Nine plots have a weak degree of soil contamination by the content of mobile cadmium compounds, two plots have moderate and medium contamination. In site 6, a weak level of soil contamination by the content of mobile nickel compounds and a high degree of contamination by the content of mobile cobalt compounds was established. The soils of one area are characterized by a weak level of pollution in terms of the content of mobile manganese compounds. No contamination of the soils of the studied areas by the content of zinc and copper was detected. The MPC of iron is not normalized. The most polluted is site 6 on the territory of the village. Ternivka of Bereznehuvatе TG of Bashtan district of Mykolaiv region.
Correlation analysis of the dependence of the content of the studied mobile compounds of heavy metals was carried out.
