Abstract

In model experiments, the influence of combined effect of lead contamination with a concentration of 100, 500, 1000, 1500, 2000 mg/kg and an variable magnetic field of industrial frequency (50 Hz) by induction of 300, 1500 and 3000 mkT on the enzymatic activity, microbial soil biomass and phytotoxicity of chernozem ordinary, brown forest soil and seropeski. Depending on the concentration of lead and the level of induction of an variable magnetic field, factors had both a synergistic and antagonistic effect. The most sensitive to the combined pollution were seropeski. The main contribution to the change in biological properties was made by lead pollution; the contribution from variable magnetic field and the combined effect of factors was smaller.
