NON-METALS ACCUMULATION IN SCOTS PINE (PINUS SYLVESTRIS L.) WOOD AND BARK AFFECTED WITH ENVIRONMENTAL POLLUTION

摘要

In order to specify the influence of the environmental pollution on non-metals accumulation in Scots pine trees, studies of nitrogen, sulfur, phosphorus and chlorine content were performed on samples obtained from pine stems gained from the Ist, IInd and IIIrd zone of industrial damages (tree degradation). Samples were collected from butt-end, middle and top sections of the stem in sapwood, heartwood adjacent sapwood, heartwood and in bark. Significant influence of the environmental pollution caused by nitrogen industrial plant on the nitrogen content was denoted. Nitrogen content was decreased (in relation to samples from non-polluted area) especially in sapwood and bark. Additionally, chlorine content both in wood and bark was increased.
