Variability of Aerosols and Chemical Composition of PM10, PM2.5 and PM1 on a Platform of the Prague Underground Metro

Popis výsledku v původním jazyce

Measurements of PM10, PM2.5 and PM1 and particle number concentration and size distribution were measured for 24 h on a platform of the Prague underground metro in October 2013. The three PM fractions were analysed for major and minor elements, secondaryinorganic aerosols (SIA) and total carbon (TC). Measurements were performed both when the metro was inoperative and closed to the public (referred to as background), and when the metro was in operation and open to passengers. PM concentrations were elevated during both periods, but were substantially increased in the coarse fraction during hours when the metro was in operation. Average PM concentrations were 214.8, 93.9 and 44.8 mg m 3 for PM10, PM2.5 and PM1, respectively (determined gravimetrically).Average particle number concentrations were 8.5 103 cm 3 for background hours and 11.5 103 cm 3 during operational hours. Particle number concentrations were found to not vary as significantly as PM concentrations throughout the day. Var
