Since 1991 the Regional Geoecological center (today - Federal State Unitary Enterprise Urangeo) by request of the Administration of Saint Petersburg has researched soil pollution in the city. Now, at the expense of various financing sources, thanks to the main contribution of the Committee on environmental management, environmental protection and ensuring environmental safety of the Administration of St. Petersburg heavy metal soil pollution inspection is carried out on the network 200 x 200 m and the area about 830 sq.km including the main residential presincts, industrial areas and potential development zones of the city.

In 2008 a systematic process of assessment of soil condition in Kolpino district was carried out. Besides, inspection of the land parcels planned for the construction in the rest of the city was conducted.

Soil quality assessment from the point of view of their pollution degree is carried out according to the Russian legislation in two ways: by comparison of the revealed maintenance of ecological toxicants with standard ones and calculation of the total soil pollution indicator with the subsequent comparison of the received values with a ranking scale according to which value over 32 conventional units is considered dangerous.

You can get more details on soil pollution in St. Petersburg from the annual analytical review "Environmental protection, environmental management and ensuring environmental safety in St. Petersburg" issued by the Committee on environmental management, environmental protection and ensuring environmental safety of the Administration of St. Petersburg. One can find this publication in all large libraries in the city: Central city public Library named after V.V. Mayakovsky, National Library of Russia, Library of the Russian Academy of Sciences, central regional libraries and university libraries.
