Heavy metals in the soil-­vegetation cover of the selitebnii landscape of the city Arkhangelsk

Korelskaya T.A., Popova L.F.

Статья научная

Soils of the selitebnii landscape of Arkhangelsk is the most polluted of the forms of heavy metals (Pb, Cu and Zn) in the old part, which may be related to the type of underlying soils. The soils have a high availability of Arkhangelsk mobile forms of Cu and Zn, but the actual reserves are deficient in Co, Ni and Mn. Accumulation of heavy metals in the city plants is more intense that in natural conditions and increases in the number of row of Fe < Ni < Co < Pb < Cu < Zn.

The influence of radio nuclides 137Cs и 90Sr on the soil microbial community on the territory of the underground nuclear explosion ‛Kraton- 3’ (Yakutia)

Erofeevskaya L.A., Alexandrov A.R.

Статья научная

It was first conducted the microbiological studies of the soils in the underground nuclear explosion ‛Kraton-3’ (Yakutia). It was found that the soil area has toxicity to micro-and makroflore, inhibit seed germination, seedling development of the green part and the root system of plants. With theoretical and practical approaches, it is necessary to further study and evaluate the factual capacity of Cs137 and 90Sr in the microbial community to assess the environmental hazard or safety of radioactive waste and its possible effects on human health, animals, and, in general, the environment in the northern latitudes.
