sediments in Russian regulatory documents. According to the geochemical properties and mineral compositions of the components, soil is the closest to the bottom sediments (although there is less organic matter in the sediments). The approximate permissible concentrations are determined for acid-soluble forms of metals in soil (Hygienic Standards 2.1.7.020-94, 1994 and Hygienic Standards 2.1.7.2511-09, 2009). Regulations apply to soil at settlements, agricultural areas, sanitary protection zones of water sources, and territories of resort areas.
