Abstract
In Ukraine, there is still a great number of unused, unidentified and substandard pesticide preparations (PPs) and other toxic substances which have an extremely dangerous impact on humans and other living ecosystems and the environment. Besides, more than 75 thousand tons of pesticides are imported and produced annually in Ukraine, but some of them are not used during the period of their suitability. Consequently, when stored mostly in dilapidated warehouses and repositories of agrochemicals, as well as in the open areas, they fall into underground and ground water, and then through trophic chains into the organisms of living systems, causing severe poisoning and diseases. We note that till now, the problem of unsuitable PPs was solved only in the context of their utilization or export for processing outside the state, while the rest of this ecological problem – the restoration of soils and the remediation of contaminated lands at the state level, is not virtually solved. Therefore, the substantiation of the scientific and practical aspects of environmental safety management of such remediation processes is on time.
Highlights
The dilapidated warehouses and storage repositories of agrochemicals containing residues of unsuitable pesticides and other toxicants that under the influence of external factors were transformed into unidentified toxic mixtures are an extremely acute environmental problem
Territories and soils around the repositories of toxic chemicals are heavily contaminated with leaky PPs
We have investigated on the example of a separate warehouse of pesticides near the village of Vinnitski Khutory near Vinnytsia, that the excess of concentration of some pesticides stored there is noted at a distance of up to 500 meters and up to 6 meters deep, that is, the two-vector nature of migration [1, 12, 14]
Summary
The dilapidated warehouses and storage repositories of agrochemicals containing residues of unsuitable pesticides and other toxicants that under the influence of external factors were transformed into unidentified toxic mixtures are an extremely acute environmental problem. This is, as a rule, the territory adjacent to the warehouse of pesticides and mineral fertilizers within a radius of up to 500 meters, which was not taken care of by anyone, and until recently, almost in most cases was unproductive In this case, adjacent territories together with the repository of chemicals can range from 0.5 to 8–10 hectares of fertile land. Considering that there are several thousand of such warehouses in Ukraine, it is possible to estimate approximately the extent of environmental disaster, which is more than 10 000 hectares, that is, about 0.02 % of the total area of the state [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]
