摘要

Multiyear data obtained from a survey of benzo(a)pyrene (BP) in the soils of the Eastern Administrative Okrug (prefecture) of Moscow have shown that, over the period from 1990 to 2006, its concentration increased from 492 to 645 ng/g, exceeding the background value by 145 to 190 times. Two stable and strongly contrasting anomalies of BP have been identified as a result of mapping its distribution across topsoil horizons. The multiyear BP dynamics is reflected on the map of its annual increase in concentration. The intensity of soil contamination by this compound is caused by type of land use and by their sahnity level. The average BP concentration in the okrug's soils amounted to 32.2 maximum permissible concentration (MPC). Soils with levels of contamination deemed extremely dangerous or dangerous are predominant, and their area in 2006 reached 96% of the total territory covered by the survey.
