This paper focuses on the problem of urban soil contamination with heavy metals in Novosibirsk city. The concentrations of mobile forms of heavy metals in soils of district of Novosibirsk affected by a non-ferrous metallurgy plant (Novosibirsk Tin Plant) were assessed. Soil samples were taken at 9 sites. Flame atomic absorption spectrometry and inductively coupled plasma mass spectrometry were employed for chemical analysis of the heavy metal contents. The study demonstrated that the maximum permissible concentrations (MPCs) for arsenic, lead, nickel, cadmium, copper, zinc and chromium were exceeded in the analysed samples and the concentration of mercury is in normal levels. The concentration of heavy metals decreased with increasing distance from the plant. According to the integrated pollution index soil contamination is classified as extremely hazardous.
