ASSESSMENT OF THE LEVEL OF ENVIRONMENTAL SECURITY OF AGRICULTURAL LANDS ON THE EXAMPLE OF PETRYKIVKA COMMUNITY OF DNIPROPETROVSK REGION

A chemical analysis of agricultural soils, on which various approaches to agricultural land treatment using mineral and organic fertilizers are involved, was carried out on the example of Petrykivka community of Dnipropetrovsk region. Concentrations of mobile forms of heavy metals were determined: cobalt, chromium, copper, nickel, lead, zinc and manganese in data samples soils It was established that there is no exceedance of the maximum permissible concentrations of mobile forms of heavy metals in the soil samples of the studied areas. When comparing the obtained concentration values with the background indicators, it was found that they were mostly exceeded. The assessment of the level of ecological safety of the agricultural lands of the Petrykivka community of the Dnipropetrovsk region was carried out using the selected methodology. It was established that one of the experimental sites has a moderately dangerous level of pollution and carries a potential danger in the flow of mobile forms of heavy metals to the components of the environment and to humans in particular. For this area, recommendations have been made to control the amount of mineral fertilizers used and reduce the level of soil contamination by heavy metals.
