Case Studies of Aerosol Pollution in Different Public Transport Vehicles in Hungarian Cities

In this case study, aerosol pollution and passenger exposure were investigated while travelling on different public transport vehicles in Hungary. Two sampling campaigns carried out: one autumn 2012 the other spring 2014. Concentration, elemental composition size distribution of samples determined order to characterize atmospheric particulate matter (APM) inside vehicles. The concentration PMcoarse fraction varied between 29 354 μg m−3, PM2.5 concentrations found be 12 192 m−3. This was significantly (2–19 times) higher than outdoor values. main sources increased resuspended mineral road dust, including salt fertilizers, direct exhaust Rail abrasion disinfectant cleaning materials also contributed considerably Moreover, organic fibrous particles great number by single particle analysis using scanning electron microscopy (SEM).
