Abstract:

The reaction of soil microorganisms to the contamination of soil with PAHs was evaluated. Eight variations of soil and water contaminated with PAHs taken in Power Plant Station and Fergana Oil Purification Plant in Angren, Tashkent, Uzbekistan. Contaminated soils with PAH are taken in the Station by direction (east, west, south and north) and windy conditions of soil. Soil microbial properties were evaluated on the basis of seven principal physic group amount of microorganisms (ammoniators, actinomycetes, fatty acid bacteria, micromycetes, oligotrophic microorganisms that grow non-nitrogen condition, cellulolytic aerobes and anaerobes) on soil and water.
