Abstract
ABSTRACTPolycyclic aromatic hydrocarbons (PAHs) and their nitrated derivatives are responsible for mutagenic activation of ambient air. The aim of the study was the assessment of exposure for PAHs and nitro-PAHs in the urbanized region in Poland in comparison with the non-urbanized region and assessment of seasonal variation of PAHs and nitro-PAHs. Concentrations of 12 PAHs, 8 nitrated PAHs in total suspended particulate matter in air of urban and suburban (reference samples-mountain region) region in Poland during four seasons have been shown. The method of solvent extraction of particulate matter, fractionation organic extract and HPLC and GC/MS analysis were applied. The concentrations of PAHs and nitro-PAHs were 10–100 times lower in reference samples than concentrations of PAHs and nitro-PAHs in urban region in summer. The concentrations of PAHs and nitro-PAHs were highest in winter. The exposure profiles of PAHs and nitro-PAHs in four seasons have been shown. The correlation factor between concentrations of PAHs and nitro-PAHs was found. Important influence of ambient air temperature for PAHs and nitro-PAHs concentrations was shown. Obtained results suggest that the coal combustion in Polish households was the main source of PAHs and their nitro derivatives contaminations. Emission from transport sources is a secondary source of air pollution in urban areas.
