Устойчивость бурых лесных почв к сочетанному загрязнению свинцом и переменным магнитным полем

The influence of lead contamination, an alternating magnetic field, as well as combinations of such properties on brown forest soil, the activity of enzymes phytotoxicity and the soil biomass was investigated. Lead concentrations in the soil were 100, 500, 1000, 1500 and 2000 mg/kg, the level of induction of the alternating magnetic field – 300, 1500 and 3000 mkTl. Pollution had a significant and different effect on the biological properties of the soil. Nature and extent of this effect varied with the level of exposure of each of the factors, while they were not linear. The greatest contribution to the change in indicators of combined polluted soil introduced lead (50–77 %), but the fact of the interaction of two factors also contributed (17–25 %).
