It was shown that some emergent aquatic plants may be used for treatment of waste waters. The plants have specific composition of surface lipids (SL). The SL composition was found to be changed under the influence of water pollutants. These changes concerned the processes of elongation and desaturation of the SL components. The response to contamination was specific for each species.

On the basis of research of litter mesofauna in four forest biogeocenoses of the Poltava region the trophic-weight models of invertebrate communities are creating. The biomass differentiation between trophic levels, weight and taxonomic structure of the separate levels are analysed. The differentiation and similarity of the trophic-weight models of litter invertebrate communities are discussed.

The paper is devoted to the different methods of the field research of the birds’ colonies. By the example of common heron the assessment methods of spatial structure of the population and its influence on a biogeocoenosis are described. Most acceptable and available techniques are proposed.

The changes of some agrochemical properties of soils of model plots closed to industrial enterprises with fluoride atmospheric emissions were studied. The alkalescence of soils at the plots was found. The reduction of content of the mobile forms of phosphorus, nitrite and nitrate forms of nitrogen and humus level in soil is caused by the increasing amount of nitrogen of ammonium compounds.

Basic descriptions of blossoming of some ornamental flowering plants under condition of environmental pollution by motor transport emissions are presented. Amount of flowers (or inflorescences) per individual plant is the most informative test-index at highways territories. Petunia × hybrida and Salvia splendens are proposed to be a test object for phytomonitoring.

Influence of a humus of different origin to a catalase activity in leaves, roots and corns of the pure lines (В-73, ГК-26, П-346 and F-2) and hybrid (Pioneer 3879) of Zea maize was studied. The humus was originated from the preparations Floreks bio, Floreks N and Floreks PK. The research was carried out in the phytotron, in the field and model experiment.

Extent of toxic influence of cadmium and nickel joint action on growth and development of the maize germinant and plants’ adaptation capabilities to negative influence of heavy metals was studied. Specific protective activity of the phytohormones Emistim C and Zeastimulin under conditions of the cadmium and nickel joint action was shown.

Biodiversity of soil invertebrates on the model plots of Bel’gard International Prysamars’ky Biosphere Station of the Dnipropetrovsk National University is under consideration. Number, biomass and distribution of the invertebrates on the right-bank of Samara River were ascertained in 2003–2005.

The article touches upon the burning questions of environmental contamination with high-polymeric compounds. The possibility of these compounds transformation into energy carriers with the help of anaerobic methanegenic associations has been estimated. The mechanisms of interaction between certain populations of methanegenic association microorganisms have been studied. The selection of the microorganisms, which took part in the transformation of polymers into energy carriers, has been carried out. Some artificial microbial populations have been created. The influence of outer factors on the processes of intensification and increase of obtained amounts of energy carriers in the course of high-polymeric compounds transformation by anaerobic microorganisms has been studied.

Research of biochemical parameters of two aquatic amphibian species was conducted in biotopes of the channel Dnieper-Donbass. Finding data showed a high level of protein and lipids in animal organs and tissues. That testifies to the large energy resources of the organisms and allows estimating both separate individuals and populations as stable ones – which are able to the further growth.

Benzene content in organs and tissues of tailless amphibians from the habitats different on the degree of contamination (sewage area Dniprovsko-Orelsky nature reserve of chemical enterprises and control biotopes of the Dniprovsko-Orelsky nature reserve) was studied. The coefficients of benzene bioaccumulation in organs and tissues were calculated. An estimation of organs as the benzene micro - and macro concentrators is given. Comparative analysis of the benzene accumulation in aquatic and terrestrial amphibians has been prepared.

54 staphylococcus strains with different resistance levels to a number of antibiotics have been extracted from the reproductive canal of women who had a miscarriage. The respiration activity of the selectved cultures has been studied. Endogenic respiration processes in staphylococcus cells intensified in consequence of the development of antimicrobial medication resistance.

Influence of fossorial activity of European mole Talpa еuropаеа on number and distribution of soil microorganisms under conditions of cadmium pollution of the soil is characterized. Mammals’ fossorial activity is an important natural ecological factor that contributes to microflora rehabilitation and development under conditions of contamination.

Influence of heavy metals on growth, biosynthesis, lytic action and growth stimulating activity enzymes complex of Streptomyces recifensis var. lyticus was studied. It was showed that salt of plumbum' has positive influence as on biosynthesis hydrolases (lytic endopeptidases, proteinases, amylases) as well increase growth stimulating activity of preparation relatively the yeast
