- W2953743931 abstract "Objective: Soil-ecological study of the area for the benzo(a)pyrene presence. Methods: Chemical analysis of soil samples (determination of benzo(a)pyrene). Results: When carrying out engineering-ecological surveys on the land plot near airport Levashovo identified sites contaminated with benzo(a)pyrene. Soil and environmental work, as part of the engineeringecological survey was carried out for examination of the soil horizons in geochemical, epidemiological and toxicological characteristics. On the territory of the investigated object 160 selected samples of the soil at the depth of 0,0–0,2; 0,2–1,0; 1,0–2,0; 2,0–3,0; 3,0–4,0 m. Analyzing the obtained data, constructed charts changes in the concentration of benzo(a)pyrene with depth. For analysis of the selected closest points to the dump-depth sampling of which is from 0,0 to 1,0 m. It is established that with increasing depth, the contamination of benzo(a)pyrene is reduced by almost 40 % from an initial reading. At points № 3 and 4 the excess is observed only on the surface. The maximum rate of exceedance is observed at point № 59 on the surface and is reduced from 0,2 to 1,0 m. Analysis of the sampling points located closer to the airfield, the depth of the selection is from 0,0 to 2,0 m, showed that the concentration of benzo(a)pyrene decreases with the deepening, but only slightly. In accordance with the obtained results, all studied territory has exceeded for benzo(a)pyrene in 3–3,5 times at the surface and 1,25–1,5 times in the depth. Practical importance: It is proposed to isolate the anthropogenic sources from possible migration of benzo(a)pyrene by using geochemical barriers. As such barriers can be used in different industrial wastes if they have geo-ecological reserve." @default.
