Abstract: The dissemination of heavy metals (Cr, Pb, Cd and Ni) near the landfills was analysed by measuring the concentrations of their mobile forms in soil on different distances from the place of leachate outflow at Stadnytsia landfill (Vinnytsia region, Ukraine). Exceeding the limit was not observed for any heavy metal. The highest levels are about 0.5 of limit values for Cr and Pb. A strong correlation between the distance from the landfill and the concentration is observed only for Cd. The dependence is ambiguous for Pb and Cr, perhaps due to the spatial proximity of sampling points and the existence of predominant migration routes of mobile forms of these metals. The landfill influence on the content of Ni mobile forms in nearby soils is most likely minimal. The research also confirms that migration of heavy metals depends on the conditions at landfill and on its compliance with requirements.
