Pollutants emission from the automotive transport exemplified in Poland since 1990

Abstract

On the background of statistical data on the dynamic quantitative growth of automotive transport (ATM) that has more than doubled since 1991, temporal changes and a share of gaseous and particulate emissions from this source in total emission have been analyzed. Most of the emissions, of which major ones were NOx, CO, VOC and CHG, were found to decrease substantially due to the stringent environmental policy. Survey of 6 Polycyclic Aromatic Hydrocarbons (6PAHs) along a motorway and a local road displayed high accumulation of benzo[a]pyrene BaP and other PAHs in soil (0-20 cm) and their vertical migration to deeper layers. Concentrations of PAHs in soil, both along a motorway and a local road appeared to exceed MCL in soils of A class (protected areas) and B class (agricultural soils) for one-two orders of magnitude that disqualifies these lands for agricultural use.
