Chemical Composition of Coniferous Needles of Siberian Spruce under the Conditions of Technogenous Pollution in Kemerovo City
O. A. NEVEROVA
Abstract
Peculiarities of the chemical composition and the accumulating capacity of coniferous needles of Siberian spruce (Picea obovata Ledeb.) growing in various districts of the Kemerovo City have been elucidated. It has been established that the maximal accumulation of chemical elements of the technogenous group (Pb, Cd, Cu, Fe) as well as that of sulphur and nitrogen which are the main components of gaseous pollutants of the atmosphere (sulphur, nitrogen and ammonia oxides) is characteristic of coniferous needles of the Siberian spruce growing in the Kirovsky and Rudnichny districts of the city, which permits concluding that they are the most polluted ones.
