Thermo-electric power stations using coal are very important and complex polluters, due to the chimneys for burning gas evacuation which represent the main high sources of environmental pollution, while the ash dumps пїЅ are lower sources. The Doice?ti thermoelectric power station built in 1952 is located in the Subcarpathian hill area, on the Ialomi?a Valley, constituting a source of heavy metals pollution of this zone. From the geographical viewpoint, the studied territory can be included in the Subcarpathian Cu...

Urban sprawl and land abandonment are the major threats to agricultural areas, as highlighted the European Environment Agency. Bucharest metropolitan area is a proposed metropolitan area project, aiming to reach 2700 km2 in an intermediate stage. This area would include Bucharest City and other 62 surrounding LAUs from Ilfov, C?l?ra?i and Giurgiu Counties. The paper aims to assess the dynamics of soil sealing and soil landscape patterns and to evaluate soil productivity lost due to the urban sprawl within the Buch...

We aimed at identifying the microbial response and associated release of CO2 and CH4 in/from thawing soil that has been permanently frozen. For that we performed an in situ field-based incubation experiment in a rim of ice-wedge polygon on Samoylov island, Lena Delta, Russia (72пїЅ22пїЅN, 126пїЅ28пїЅE). Frozen "buried' organic matter were taken from eroded Lena river bank and transferred to the soil surface in a rim of ice-wedge polygon. The principle includes that formerly frozen soil is moved to the active layer...

The present study reports on the geochemical composition of soils and bacterial and fungal isolates determined in the soils surrounding the Komsomolsk tailings, Kuznetski Alatau, Russia. The areas with high concentration of As, Sb, Cd, Pb, and Zn were revealed. The assessment of metal and metalloid contaminants was conducted on the soils using Pollution index (PI), Enrichment Factor (EF), and Geo-accumulation Index (Igeo). The indexes indicated serious Pb, Cu, Zn, Cd, Co, As pollution especially for soils sampled ...

Along the whole history, the human civilizations were depended mainly on the soil fertility and further on the ecosystem well function and its appropriate characteristics. These functions (as natural processes occurring in ecosystems) depend on its structure (on biotic and abiotic constituents respectively) and provide ecosystem services. The paper emphasized the way that one of the ecosystem services, essential to our health and well being, as the пїЅregulation of the nutrients and their uptake? arises from the i...

The coal-fired power stations are particularly complex polluting agents, furnishing simultaneously, high and low environmental pollution sources, through the chimneys for burning gases evacuation and the ash dumps, respectively. The Deva-Mintia coal-fired power stations has an installed power of 1260 MW, six power units of 210 MW each group having two steam boilers of 330t/h, the energy being produced by the coal extracted from Jiu Valley mining area. Coal-fired power station Mintia is located in South East Transy...
