Evaluation the change of biological effectiveness of nickel solution in magnesium presence using the plants test objects

The evaluation of magnesium contribution in the reduction of biological activity of solutions, containing nickel ions, which are the main toxicant of technogenic landscape in neighbourhood of copper-nickel enterprise was carried out. It was shown that not high concentrations of nickel in solution (0,5 и 1,0 mg/l) has given on the plant test-objects rather stimulatory than inhibitory action that was primarily expressed as germination increase of the onion seeds. At adding magnesium in concentration of 50-300 mg/l in nickel containing solution the reducing of nickel biological efficiency was taken place.
