Concentrations of 16 PAHs different molecular weight and carcinogenic potency were measured in PM2.5 aerosols collected the coastal zone southern Baltic Sea (Gdynia, Poland) during end heating beginning non-heating season 2012. Obtained results showed that coal combustion (pyrogenic source) contributed to highest emission season. However, similar concentrations highly detected period. The analysis prevailing wind directions, air mass trajectories diagnostic PAH ratios revealed addition land transport (mainly from diesel vehicles), increase sea shipping traffic high PAHs. We conclude increasing maritime activity region might have an adverse effect on both environmental human health. Therefore, it should receive more attention by Polish government as a pollutant source.
