FTIR spectral analysis of PM10 and PM2.5 particulate matter over the urban area of Palermo (Italy) during normal days and Saharan events

2010

The principal sources of particulate matter in Palermo urban area are gasoline and diesel-powered vehicles, domestic heating, resuspension of soil dust and a geogenic source which includes soil erosion, marine aerosol and sporadic Saharan events. Annual average PM10 and PM2.5 concentrations result 27.8±9.8 and 21.3±5.1g/m3. The highest mass levels, 246 and 65 g/m3 respectively for PM10 and PM2.5, were observed during Saharan events. For the present study, which uses the ATR-FTIR spectroscopy to provide insights on the chemical composition of airborne particulate matter, a total of 89 filters were collected: 13 PM10 filters from a sub-urban background station, 36 PM10 and 40 PM2.5 filters …
