“…These field experiments were conducted in accordance with the technique elaborated earlier [7] [16]. The polluted soil was replaced from the zone of techogenesis to the Institute's stationary field, where earlier the pollution was absent.…”

Some results of monitoring (for the period from 1992 to 2005) related to transformations of carbon in agroecosystems of Baikal Siberia (Russia) characterized by unpolluted grey forest soils as well as the soils technogenically polluted with heavy metals are discussed with use the unique approach to integrated assessment of the agroecosystem's functioning regime. The peculiarities of accumulation of carbon in soil microbial biomass and CO2 emission during the years differing in climate conditions are demonstrated. Analysis of formation of net-mineralized and (re)immobilized carbon is conducted, their ratio being used for the purpose of assessment of the level of influence upon the agroecosystem. The agroecosystems having technogenically polluted soils are characterized by processes of the soil microbial biomass reduction and by an obvious increase of CO2 emission into the atmosphere. Negative changes, which are bound up with carbon transformation, are intensified under unfavorable climate conditions. Intensification of processes of carbon net mineralization and, vice versa, lowering the intensity of processes related to carbon (re)immobilization (especially under the effect of soil pollution and climate changes) provoke instability of the agroecosystem and cause formation of a new regime of its functioning.

“…The study of prolonged fluoride pollution of soils near the aluminum smelter in Central Slovakia revealed the decreases in microbial and enzymatic activities as well as in soil microbial biomass C to organic C ratio (García-Gil et al 2013). The most studied territories of Russia, exposed to the emissions from aluminum industry, are located in the vicinity of the Krasnoyarsk and Irkutsk alu-minum smelters (Demidenko and Zhbankichov 2014, Tandelov 2012, Kozlova et al 2011, Kirillova and Pomazkina 2014, Sokolova and Zorina 2015, Lomovatskaya et al 2014, Pomazkina et al 2008. The response of the microbial soil components was studied through the index of specific respiratory activity (Sokolova et al 2011).…”

The analysis of algal-mycological complexes in Albic Podzolic soils affected by emissions of the Kandalaksha Aluminum Smelter (KAS) was carried out. The number and biomass of microscopic fungi in the maximum fluorine-polluted zone (fluorine-content >1000 mg/kg) more than 2 times lower than in distanced areas and amounted to 17.3 thousants colony-forming units/g and 1.33 mg/g respectively. Altogether, 31 species of soil fungi were isolated. The species Penicillium trzebinskii and P. miczynskii dominated the zone of maximum pollution. P. glabrum, P. spinulosum, and Memnoniella echinata prevailed in the zones of moderate pollution and background. The part of opportunistic fungi in contaminated soil increased in comparison with the background soil. The reduction of dark-colored fungi biomass in contaminated soil was noted. In total, 56 species of eukaryotic algae and 7 species of cyanobacteria were found. Among green algae, the species from families Chlorophyceae and Trebouxiophyceae dominated in all plots. In the zones of maximum and strong contamination, 53 algae species were found including xanthophytes, which were absent in unpolluted areas. The number of viable cells in the litter of the maximum contaminated soils varied from 100 thousand to 1.5 million in 1 g of absolutely dry soil. The species composition of algae and cyanobacteria in these soils showed the characteristic features of the Arctic biological soil crusts.
