An impact of traffic pollutions on content of some chemical substances in wood and bark of white mulberry (Morus alba L.)
The trunk of a tree that grew about 3 m from the express way in central Poland was cut into 200 mm high disks and then studied for extractives, mineral substances, N and NO3-, SO42, and HPO42- anions in disks obtained from different heights of the trunk (in the range of 0.1-2.2 m from the ground) as well as from zones located at different distances from the trunk core. The content of the extractives (eluted with a mixt. of EtOH and C6H6 1:1 by vol.) was the largest in samples from zones located near core similarly to the content of the analyzed anions. The bark samples had the highest contents of minerals and N. The contents strongly depended on the sampling height.
