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.

Risk values have been obtained using a situational risk model that enables to identify the storage buildings (objects) on the territories where special measures should be taken to reduce and eliminate pollution. 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. The risk characterization stage assesses the frequency and magnitude of toxic effects, their reversibility or irreversibility. One of the methods used is the method of comparison of the results obtained with similar projects and studies. An important condition for the introduction into the general farming use of territories in the zones affected by the former pesticide and agrochemical storages in these settlements is the search for the methods of restoration and purification of soils of these territories from xenobiotics. Only after conducting the work on soil purification and availability of the inspection results showing positive changes, it will it be safe to grow agricultural products.

Accidental pollution incidents have caused a major threat to water safety of drinking water sources. However, few studies have focused on quantitative risk assessment of pollution incidents in a watershed which contains drinking water sources. A coupling model consisting of the Seveso III Directive, SWAT, and MIKE21 models was constructed for risk assessment of sudden pollution incidents at the watershed scale. The potential hazard of risk sources (e.g., industrial enterprises), the vulnerability of risk receptors (e.g., drinking water intakes), and the environmental risk of different sub-regions of the watershed were evaluated by this model. In addition, a case study was applied in Hongfeng Lake watershed (HLW), where the Hongfeng Lake drinking water source is located. The results showed that about 68% of the industrial enterprises in the HLW were potentially hazardous according to the Seveso III Directive, including 5 high hazard enterprises, 13 medium hazard enterprises, and 37 low hazard enterprises, most of which were concentrated in the coal mining, chemical production, and building material industries. The HLW was divided into the Yangchang River watershed (YRW), the Maiweng River watershed (MRW1), the Maxian River watershed (MRW2), the Houliu River watershed (HRW), and the lake area by the hydrological characteristics, among which, the vulnerability index of YRW was the largest. Besides, it was essential to consider the vulnerability assessment of drinking water intakes when conducting an environmental risk assessment in the HLW. Regional environmental risk grade of YRW, MRW1, MRW2, HRW, and the lake area was high, medium, low, low, and none, respectively. The environmental risk assessment results showed good consistency with the pollution characteristics and spatial distribution of industrial enterprises in the HLW. Furthermore, the theory of a three-level prevention system for “risk sources–water body connection–water intakes” was proposed for environmental risk management in the HLW. Overall, the case study in the HLW indicated that the coupling model proposed in this study had a good compatibility for environmental risk assessment of sudden water pollution incidents in a watershed.

The Impact

There is presented a unique Russian computer information and predictive TERA (Tools for Environmental Risk Assessment) system aimed to carry on studies of the assessment of health risk related to the impact of chemical compounds that pollute the various environmental objects. There are considered main calculation modules of specialized databases, as well as the main identification table - TERAbase, allowing to observe all the methodological requirements and recommendations provided by the sanitary legislation, for doing so and for the examination of scientific and practical work on risk assessment to public health, accreditation and certification for risk assessment bodies. There is indicated the direction of solving the problem of information support for risk assessment work for health.

The goal of this article is to demonstrate the general principles of environmental risk assessment for hazardous substance storage. Matrixes, HAZOP, FTA, and Monte Carlo are examples of methodologies that can be used in conjunction with one another. Environmental assessment, which anticipates the physical, biological, and social repercussions of a project, is used in conjunction with risk assessment. A computer system can be utilized to determine the spill's impact region. When evaluating the probability of an event, and hence the risk, it is vital to have correct statistical data in order to generate more precise conclusions. Following international guidelines is the greatest method to reduce danger.

Risk Potential

At present, the environmental risk assessment of major accidents is mainly carried out for stationary risk sources. Only marginal attention is paid to mobile risk sources, while the currently available methodologies require a relevant expertise and time for their application, which is only partially possible in most scenarios. In the present study, an integrated approach to environmental risk assessment in the transport of hazardous substances (iTRANSRISK) was developed. The approach proposed is based on the principle of index-based assessment of leakage scenarios involving toxic and flammable substances during transport, in the context of indexing environmental vulnerability. The key point of the method is the conversion of local-specific data concerning the risk potential of the transported substance, the consequences and the probability of a major accident, and environmental vulnerability assessment into a single entity. The created integral approach is proposed for the needs of carriers of the hazardous substances and the state administration bodies. The proposed approach is determined for the screening risk assessment at the beginning of the process of the planning a suitable transport routes and the results are for information only. An example of the application of the iTRANSRISK integrated approach is demonstrated considering an explosion scenario following a propane tanker leak (18 t) in a forested area, with moderately susceptible soils and no surface water or groundwater affected.
