In course of the joint researches realized in Belarus and Russia were studied the influence of pollution of sod-podsolic sandy loam soil, ordinary chernozem and chestnut soil by heavy metals on accumulation of these ele¬ments in barley (Hordeum vulgare) and lupine (Lupinus) plants. Various degree of mobility of heavy metals in sod-podsolic soil, chernozem and chestnut soil was established. Accumulation of heavy metals in green mass and grain of lupine and grain and straw barley was shown at different levels of soil pollution by them. Correlation dependences between heavy metals content in plants and the content of gross and mobile forms of heavy metals in soils were presented. At pollution of ordinary chernozem and chestnut soils by copper at the maximum allowable concentration level (MAC) a copper content in the grain did not exceed the permissible limits. Zinc concentrations in barley exceed the MAC level in ordinary chernozem - at a level of 140 mg/kg, in chestnut soil - 109 mg/kg. Lead accumulation in barley grain at the MAC level and above was found at the background of the gross content of lead in chernozem and chestnut soils. In sod-podzolic contaminated soils maximum residues level exceeding for zinc content in lupine green mass was set at 55-110 mg/kg (1-2 MAC), copper - 165 mg/kg (5 MAC ), lead - 64-160 mg/kg (2-5 MAC).
