Nitrate pollution of plants on soils with elevated heavy metals concentrations
1993
Evdokimova, G.A.
Significant nitrates accumulation in the overground part of many crops was revealed for cultivated podzolic soils polluted by emissions of non-ferrous metallurgical plants and due to other sources of heavy metals (Cu, Co, Ni). The biological quality of plants deterioration consists in heavy metals accumulation in them and in the decrease of carotene content. Higher concentrations of various nitrogen forms in plants leaves seem to be due to their accelerated sorption by roots from the polluted soils with a consequent detoxication of heavy metals ions by nitrogen compounds (proteins, free aminoacids). Liming is thought to be the most efficient way to diminish soil phytotoxicity caused by copper and nickel
