Study of life form (biomorph) diversity of terrestrial and water vascular plants is based on different approaches. In this connection the main principles of differentiation of the aquatic plant group and approaches to the classification of their biomorphs are considered. 110 species of hydrophytes, gelophyts or amphibious plants on European Russia territory fall under the category of aquatic vascular plants. Classification of aquatic plants life forms including 19 biomorphs and similar to the classification scheme for terrestrial plants is proposed. The majority of these biomorphs are creeping herbs and herbs with stolones.

Simplification of benthos communities, mass development of invasive species, reduction of a role of predators, has been revealed during expedition research of sediments of the top reaches of the Kuibyshev water basin. The reduction of macrozoobenthos contribution in an energy exchange the increasing role is got by microbic fauna of sediments that leads to change of oxygen balance in bottom water. These tendencies indicate on processes of destabilization of the Kuibyshev water basin ecosystem in the present time.

Heavy metals (Cd, Zn, Cu) and agroameliorants effect on biological activity of the soddy-podzolic soil (carbon dioxide release; denitrifying process) and barley productivity. Results of the study have shown that Zn and Cu are more toxic in comparison with Cd, because decrease the rate of carbon dioxide release of the soil in 1,6 times; the rate of denitrification in 1,4 and 2,3 times, appropriately. Usage of the long-acting fertilizer SYPRODIT on the soddy-podzolic contaminated with heavy metals soil is more effective in reducing of negative influence of heavy metals on the process of organic matter destruction and soil fertility compared to variants with nitrofoska and NPK.

In article data of physiological need of living organisms in chromium are stated, his main functions are listed, the evaluation of the content of chromium in the person's organism by results of blood researches, urine and hair is given. Briefly the consequences of influence of the deficiency of chromium are stated, and as well his overabundance to person's organism. In conclusion recommendations connected with correction of deficiency and redundance of chromium in the organism are given.

On example workman in Nakhodka Ship Repair Yard is shown influence of the electromagnetic radiations greatly high frequencies, radiated ship RLS, on health of the people. They are shown the most assailable systems of organs and the levels of exceeding of the disease incidence of the employees of factory over similar diseases of people residing in background area.

The purpose of present research is study of polymorphism of somatometric indices of Kursk region born inhabitants in cross investigation. It was studied the somatometric indices of 215 Kursk region born inhabitants. As the result we have the data of average values of height, weight, index of body mass, circumferences of waist, arm and thigh, ratio of circumference of waist to thigh circumference, width of arm and pelvis, length of leg. In result of carrying out investigation in was determined that somatometric indices of Kursk region born inhabitants have graphic sexual dimorphism and don't distinguish from analogous average indices of Russia.

In the article the results of researches directed on revealing of ecological risk sources are considered. Scientific bases of maintenance of ecological and social safety of mountain manufacture and the actions, allowing to lower risk of occurrence of crisis ecological situations at the mountain enterprise are developed.

The article discusses the criteria of environmental safety as one of indicators of sustainable development of society. A description of the environmental situation in Western Siberia, identifiedenvironmental hazard.
