Supersite for Air Quality Measurements

The air quality monitoring station is located inside the research area of CNR in Bologna, via Gobetti. The site is classified as urban background station. The activity of the measurement station began in November 2011, in the framework of the Supersite project of Regione Emilia Romagna. Measurements performed routinely at the station include PM1, PM2.5, and PM10 mass concentration, together with particle number size distribution from 3 m to 10 m. PM2.5 samples are collected daily for the quantification of organic carbon, elemental carbon, ions, and metals. A High Resolution – Time of Flight - Aerosol Mass Spectrometer is deployed at the station to measure submicron particle chemical composition and chemical species size distribution at high time resolution (a few minutes). PM1 and PM10 size segregated samples are collected to analyze organic fuctional groups and size distribution of major chemical components (water soluble organic carbon, insoluble carbon, and ions). In addition, polar organic compounds, polycyclic aromatic hydrocarbon, and linear alkanes are investigated in PM2.5 samples as marker of specific aerosol sources.
