[Biochemical evaluation of urban soils (in case of Kemerovo)].
The study has revealed common changes in the chemical composition of soils in the town of Kemerovo. Under urban conditions, there is a reduction in pH, an increase in the carbonate properties of soil mineral part and in the content of exchange cations (Ca2+, K+, Na+) in the soil absorptive complex, a decrease in the level of gross elements (N, P, K), as well as accumulation of heavy metals (Pb, Cd, Zn, Ni, Mn, Co, Fe, Cr) and sulfates. The above changes are determined by the level of a technogenic load; and they are more pronounced in the soils located along the main roads, particularly in the districts (Kirovsky, Rudnichnyi, and Zavodskoy) with heavy traffic of freight transport.
