Influence of temerature on cadmium, lead and uranium mobile species content in the soil medium
The reserves of Cd, Pb and U in mobile forms (Me<sub>mob</sub>) in the soils after keeping the soil samples at the fixed temperature in the range from -18 to +30 °С have been determined. It was established that in the air-dry conditions the reserves of Cd<sub>mob</sub> and Pb<sub>mob</sub> in the light loamy sod-podzol soil increased with increase of temperature up to +30 °С, and in peaty soil it was up to +15 °С with further insignificant decrease during subsequent temperature increase to +30 °С. At the same time, the reserve of U<sub>mob</sub> did not change in the sod-podzol soil and increased in the peaty soil up to +15 °С and decreased in both soils during further increase of temperature up to +30 °С.
