[THE STUDY OF MANIFESTATIONS OF ENVIRONMENTAL HAZARDS AT THE REGIONAL LEVEL].

Elaborated methodological approaches to the monitoring of the state of ecological safety are based on the use of systems analysis of conditions and consistent patterns of the formation of the ecological danger search for effective means and methods of safety management. Ecological hazard is considered as a hierarchical structure, consisting of types, classes, species and subsubspecies. In industrially developed regions the most significant are technogenic and sociogenic classes. The sociogenic class of danger was proved to be primary in its formation, as the level of environmental awareness is largely determined by the degree of impact on human health and environment, manifestations of the danger of other classes are depend on it. When analyzing the state of danger there was applied the anthropocentric approach. There was used an assembly of characteristics considering the health status of the population of the certain territory under the influence of factors of environmental hazard. On the base of the colligation of literature data and the results of own observations there was suggested a generalized index of the state of the population'S health in socio-economic areas, there were selected zones with differing level of the technogenic loads and also rural areas beyond objects of technogenic impact. On results of studies there was proved the relationship between the level of the environmental hazard and state of the population's in various socio-economic zones.

[The use of waste-derived adsorbents for improvement of the human environment].

Nanostructured adsorbents based on plant waste have been derived. Optimal technological parameters of process have been established Practical application of adsorbents produced with the use of nanotechnologies gives an opportunity to improve the indices of the refining of sunflower oil and increase the extent of the purification of sewage from heavy metal ions.

[Environmental security in the region with heavy exposure to sources of man-made earthquakes].

It is set that in separate regions substantial value at the study of terms of forming of ecological danger it is necessary to spare to research of vibrations of earth surface under effect of technogenic activity of man. Influence of technogenic earthquakes is investigational on a man and dwellings apartments medical and other establishments. Levels are set also intensities resulting in psychological discomfort.

[Use of blue-green algae for biogas production].

Perspectives for nature protection and energy-saving, by using blue-green algae, are discussed. Utilization of their phyto biomass for biogas manufacture will lead to the environmental normalization of the Transdniestria and allow one to have about 19,000,000 m3 of methane only from the water area of only one Kremenchug water basin each vegetative period (70 days).
