Influence of urban agglomeration environment pollution on the concentration of some non-metals in the trunk of Acer platanoides L.

The influence of environmental pollution on the concentration of some non-metals in wood and bark from trunks of Acer platanoides L. obtained from the crossroads of Platynowa and Towarowa Streets and KrakowskiePrzedmieście Street in Warsaw was observed. Samples were collected from approx. 30-year-old and 40 year-old trees from the butt-end and the mid-height of the trunk part as well as from the top part. On the cross-section of the butt-end and the mid-height, the following sections were distinguished: outer, middle and pith adjacent middle wood and of the butt-end part bark was obtained. The discs from the upper part of the trunks were not divided into sections due to their small diameter. The concentrations of chlorine (Cl-), nitrate (NO3-), sulphate (SO4-) and hydro phosphate (HPO42-) anions were determined using HPLC with a conductometric detector. The content of nitrogen (N) was examined with the Kjeldahl method. The influence of the environmental pollution caused by urban agglomeration on the nitrogen content was denoted. Additionally, chlorine anions concentrations in wood and bark were increased.

Influence of urban agglomeration environmental pollution on content of chosen metals in bark, roots and wood of norway maple (Acer platanoides L.)

Chosen metals contents were analyzed in Norway maple (Acer platanoides L.) in bark, roots and wood samples collected from the polluted environment. Samples were gained from three cca. 40-year old trunks, which were grown on Krakowskie Przedmieście st., next to the St. Anna church in Warsaw, Poland. Wood of trunk and the main roots, as well as bark from butt-end section were also sampled. Contents of Ca, Mg, Mn, Zn, Fe, Al, K, Na and Sr were examined with the application of spectrometric methods. The results show that environmental pollution significantly influences the content of examined elements. The change of Na content is the most spectacular. Its content is hundred times higher, in wood and bark, as well as in the main roots, in relation tree from non-polluted environment, what is probably caused by urban environment salinity.
