Heavy metals in Kaliningrad anthrosols

Abstract

Soils which are involved in urbanization process are under negative influence and are
polluted, particularly, with heavy metals. Moreover, the soils of Kaliningrad are polluted by
industrial and household waste, building dust, and also by pathogenic microorganisms and
finally become the most polluted environment.
Quantity of heavy metals falls with atmospheric precipitations on the surface within
Kaliningrad has been given. Park zones with a natural soil cover and wide-leaf vegetation are
estimated as pure territories in Kaliningrad (Ashmann Park). The average content of heavy
metals in the parking areas with natural soils are shown.The high concentration of heavy
metals in soils is observed in city residental areas. Quantity of heavy metals in soils has been
researched in these areas.
According to landscape-geological researches in various areas of the city shows that the city
territory is characterized by a high level of heavy metal accumulation in soils. Urban
territories are under different-powerful pressure through heavy metal-carried atmospheric
flows. The most powerful pressure can be observed within city territory.
Ecology-geochemical researches show that the urban ecological situation is the combination's
result of natural and anthropogenic factors. Natural landscape-geochemical factors have great
influence to geochemistry of urbanized territory. Nature factors have transforming role to
heavy metal migration. But now the problem of influence has not been researched properly.
