Purpose: development of hygienic standards of content of NP in soils of settlements according to their functional purpose and planning IR-spectrometry, experimental research (the study of the dynamics of migration of NP in the soil), sanitary, and statistical. Results and their novelty: it was found that for areas of different functional purpose may be used a single normative indicator of the content of the NP. So, the actual levels of NP were: on-site communal storage area - 1,520-2,018 g/kg at the production site - 12,022-25,600 g/kg; in the territories of recreational purpose, leisure zones (without a vehicle of 0.5-1.8 g/kg; in the territories of the residential zone and adjoining green zones of 1.0-3.0 g/kg, in the рarking areas of cars - the 3.0-10.0 g/kg; the piece on the ground (hard surface) - 5,0-15,0 g/kg estimated; on the highways passing raked transport - 50,0-150,0 g/kg of soil or more. Scientifically valid the levels of NP in soils of populated areas depending on the planning zone: - to 1.0 g/kg on-site green space recreational areas; playgrounds and rest areas for adults; - up to 1.5 g/kg is the estimate with hard surfaces (Parking, roads) recreation areas; - up to 3.0 g/kg in the estimate with hard surfaces (adjoining Parking lots, driveways); communal storage areas; - to 10.0 g/kg - industrial zones; up to 15.0 g/kg routes within the passage raked transportation. It is established that the influence of gasoline-diesel fraction of petroleum products on enzymatic activity and phytotoxicity of the soils is most pronounced in the soil with the lowest content of humus component (gray soils). It is established that water is the migration hazard rate of NP (model of hydrocarbon mixture - gasoline-diesel fraction NP 1:1) in the soil with the lowest content of humus is the concentration at a maximum level 15.0 g/kg soil samples. In conducting reclamation works on the soils polluted with NP, in zavisimosti from the content of the recommended NP: at 20-30 g/kg of soil - deep perepahivanii that creates the unsaturated zone and reduces the concentration of the pollutant; more than 50-100 g/kg soil - additional preparation of microorganisms-destructors of NP; more than 100 g/kg soil - possible combustion of soil (in producing regions) Product Description popup.authors Коваль Н.М.
