- Abstract
Transport caused air pollution is one of the most topical problems in the country. One of the pollutants emitted by the vehicles into the environment is nitrogen dioxide, which adversely affects the plant foliage. At nitrogen dioxide concentration of 30 μg/m3, defoliation process becomes more intense, the growth of trees becomes slower and non-specific leaf choruses symptoms become evident. The aim of research is to investigate of NO2 concentrations and assess the intensity of defoliation process within traffic areas of different intensity. To determine nitrogen dioxide content, the diffusion samplers, which are exhibited after 2 weeks and analyzed in a laboratory, are used. Crown defoliation is determined by comparing the tree to be researched with a reference tree that has all leaves (100%). The main source of nitrogen dioxide in the city is passing vehicles; therefore, research results will reflect the current situation.
