- Аннотация: Methodological problems of the quantitative assessment of benzo(a)pyrene pollution of urban soilsand their bioremediation are considered by the example of the Moscow metropolis. Available materials of scientificpublications and official reports of the “Mosecomonitoring” municipal system on benzo(a)pyrenepollution of urban soils and the patterns of its dynamics were used. The methodological basis of the study wasmathematical modeling, including both nonlinear regression analysis in the S-Plot-11 program and numericalcomputer simulation in the Matlab-7 software. Analysis of published materials reveals at least a doubleexcess of the maximum permissible level of benzo(a)pyrene pollution of urban soils at 70% of the territory ofthe Moscow metropolis, with a high probability of an extremely high degree of pollution of several dozenMPCs at 10% of the city’s area. Unlike known works in this field, the study links such a negative situation notwith the resistance of benzo(a)pyrene in soils, but with its high technogenic load. A simple kinetic model verifiedfor experimental information on benzo(a)pyrene biodegradation in soils makes it possible to assess thepermissible limits of technogenic load that guarantee the self-cleaning of urban soils from this dangerous pollutantunder the conditions of Moscow.
