[The assessment of biocenosis contamination in the region of radioactive waste storage (RWS) placing and influence of this storage on rodents].

The results of radiative and of chemical monitoring show definite contamination of this zone by 90Sr and toxic metals. The essential local contaminations of geosystems (up to 2.3 x 10(4) Bk/kg of soil) require in environmental condition assessment at biocenosis level.

Toxic aluminium and heavy metals in groundwater of middle Russia: health risk assessment.

Two approaches are distinguished in modern ecological monitoring. The first one is physicochemical analysis of environmental objects with respect to maximum allowable concentrations (MACs) of chemical substances, which is performed by standards methods in accordance with state regulations. The second approach (biological monitoring) is based on the methodology of biotesting and bio indication.

[Immunotoxicity of aluminum chloride].

Aluminum chloride was tested for its effect on primary T-dependent humoral immune response. The administration of aluminum chloride in the genotoxic dose (0.04 M) caused in mice a profound immunosuppressive effect accompanied by diminished thymic and splenic cellularity.

[The reference information system "Ecology and aluminum toxicology"].

Views of the toxicity of aluminum to man, animals, and plants and on its behavior in the ecosystems with a changing man-made loading have changed in the past 30 years. Aluminum along with its human medical consequences has been found to present problems on the acid soils in world agriculture. To systematize knowledge and to control information on aluminum and its compounds, the reference information system "Ecology and Aluminum Toxicology" whose structure is based on the developed model of an ecological aluminum cycle was designed.

[Metallothionein content in tissue and neoplasms of mice under cadmium chloride administration and gamma irradiation. Increased radioresistance in mice with elevated level of metallothionein].

It was confirmed that the survival of gamma-exposed mice became higher after preliminarily subcutaneous injections of cadmium chloride. It is supposed that radioresistance of mice is connected with the induction of metallothionein proteins by cadmium chloride.
