| Popis: | The PM2.5 and PM10 fractions were simultaneously collected in three sites of the Bari territory (South-East Italy) during winter and summer sampling campaigns. The ionic components and the carbon fractions of the PM samples were determined. The Principal Component Analysis and Absolute Principal Component Scores of the dataset allowed to identify similar PM sources in the two PM fractions: organic and inorganic secondary compounds, local and diffuse combustion processes, calcium carbonate, sea salt. While secondary and combustion compounds were mainly in PM2.5, primary and natural species were prevalent in coarse PM. Seasonal and site-specific differences were investigated. |
