The concentration of the most common heavy metals in the drainage waters and mobile soil forms of areas 1 and 2 of the Tyva Republic was studied. The average Zn, Cu, Pb, Cd, Co and Hg content in the water samples was established to be within pennissible concentration limits. Pb and Cd level in the water samples of area 2 was 1.7 and 3 times higher, respectively, than the maximtml pennissible concentration (MPC). The analysis of the soil samples from the examined areas revealed that the HM content does not exceed the MPC. However, the Cu, Pb and Cd levels were exceed in the soil ofarea 2 as compared to area 1 ( ${\rm P}<0.05$-0.01).
