Petra Velikago 2, 270000, Odessa, Ukraine aut Changes of the geological environment of the Northern Black Sea region and the chemicalization of agricultural production [Elektronische Daten] [M. Rotar] The generalization of the data available, field and laboratory investigations made it possible to estimate the pesticide inflow with large rivers to the NW part of the Black Sea, and the degree of pollution of the soil cover, bottom sediments of water bodies, confined aquifers with pesticides and ground water with nitrates. As a result of the uncontrolled use of agrochemicals their residual quantities were found in 66-93% of the samples. In connection with economic activities the greatest damage was caused to the ground water — the main source of water supply in the region: in some areas the depletion of their resources, intrusion of sea water and salt ground waters into aquifers as well as presence of residual quantities of pesticides in concentrations exceeding the maximum permissible limit were detected. Ideas on limitation of the harmful impact of agrochemicals upon the region's environment are presented here.
