Abstract
The current condition of the former pesticide storages has been investigated and characterized. All pesticide storages of Kryzhopil region are in extremely poor condition and they contain substantial amounts of unknown mixtures of unusable pesticides, which are stored in bulk in 100% of pesticide storages being a powerful source of environmental pollution by toxicants of various chemical composition. Pesticide residues in different environment (soil, water, plant) have been determined. The research results clearly prove availability of severe local sources of contamination of agricultural lands with organochlorine pesticides. There is a risk of contamination of other environmental objects with hazardous substances and a negative impact of toxic substances on human health. Migration of pesticides from the soil into agricultural products and drinking water has been identified. It has been suggested that poor environmental conditions and consumption of pesticide-contaminated agricultural products and drinking water lead to an increase in the number of human diseases. It has been found that the population of the district has much higher morbidity rates compared to the indicators of the oblast. Step-by-step environmental risk assessment has been carried out.
Highlights
The current global ecological conditions are being constantly deteriorating due to the increase in the number of anthropogenic accidents and catastrophes, negative climate change, environmental pollution, especially with organic xenobiotics
The risk assessment system consists of the steps that need to be taken in the process of environmental risk assessment for a variety of chemicals, both industrial chemicals and agrichemicals [9,10]
In Ukraine there is over 20,000t of obsolete, unusable and forbidden chemical plant protection products, much of which belong to organochlorine (OC) pesticides
Summary
The current global ecological conditions are being constantly deteriorating due to the increase in the number of anthropogenic accidents and catastrophes, negative climate change, environmental pollution, especially with organic xenobiotics. Environmental risks are defined as potential treats that may have adverse effects on the environment [1,2,3]. The risk assessment system consists of the steps that need to be taken in the process of environmental risk assessment for a variety of chemicals, both industrial chemicals and agrichemicals (including pesticides) [9,10]. This system is aimed to establish an objective risks in a particular area (including classification of risk factors and their possible effects), to provide quantitative risk assessments and damage to the human health and the environment
