ecological risk

Purpose. Describe the categories of environmental risk, the degree of their impact on the environment. Results. The place of ecological risk in the system of environmental impact assessment is substantiated. Modern methodology for environmental risk assessment involves a parallel consideration of risks to human health and environmental risks caused by disturbance of ecosystems and adverse effects on environmental components, risks of deteriorating quality and deteriorating living conditions. The reasons for the risk are unplanned events in the environment that may adversely affect the company, the progress of its plans. These include both predictable and unpredictable events. Risk factors are the conditions under which risk causes may arise. Among them are: political, scientific and technical, socio-economic, environmental and more. Conclusions. In the strategic perspective, it is necessary to improve the national environmental policy and create a national system of environmental safety and an effective system of environmental monitoring as a universal tool for its implementation. One of the tasks of this system is effective environmental risk management.

Consider the feasibility of improving methods of establishing a class of environmental hazard waste, based on the calculation method used, taking into account the content of some chemical compounds - components of waste and hygiene, physical, chemical and toxicological characteristics. The method of risk assessment of wastes to the environment, taking into account environmental criteria by experimental determination of the total toxicity of all those present in the waste chemicals to organism srepresentatives of biota, soil, groundwater and surface water. By amending the present experimental technique for technique, based on the results of biological testing of water extracts from wastes will take into account the real danger of waste for biotic component of terrestrial and aquatic eco-systems.

Districting of the Kharkiv area is presented after a possible ecological risk from the origin of emergencies on the objects of the increased danger. The map of level of danger of ecological threat is created in the districts of area and they are conducted ranking. The closeness of placing of potential sources of technogenic hazard is appraised for all districts of area which gives a right with the reliable fate of convention to talk about the measure of technogenic danger of territory of investigational districts of the Kharkiv region.
