Elemental Composition of the Leaves of Wood Plants under the Conditions of Technogenic Pollution
Chemical composition of assimilating organs of <i>Pinus Sylvestris </i>and <i>Betula pubescens </i>in the zone affected by the copper and nickel plant Pechenganikel situated in the north-west of the Murmansk Region near the borders of Finland, Norway and Russia was studied. Anomalously high concentrations of copper and nickel in the leaves (needles) of trees under the conditions of technogenic pollution were revealed. Insufficient provision of pine needles with nutrition elements - phosphorus and potassium - was discovered. Higher concentrations of copper, nickel and sulphur in comparison with their concentrations in pine needles were detected.
