| Zusammenfassung |
| A PM1 (i.e. particulate matter with an aerodynamic
diameter less than 1.0 μm) short-term monitoring campaign was
carried out in the Agri Valley (southern Italy) in September 2012. This area
is of international concern, since it houses one of the largest European
on-shore reservoirs and the largest oil/gas pre-treatment plant (i.e. the
Centro Olio Val d'Agri – COVA) within an anthropised context. PM1
measurements were performed in Viggiano, the nearest town to the COVA plant
and one of the most populated towns of the Agri Valley. During the study
period, the PM1 daily concentrations ranged from 1.2 to
8.4 μg m−3, with a mean value of 4.6 μg m−3.
Regarding the PM1 chemical composition, it can be observed that S and
typical crustal elements were the most abundant constituents of the PM1
collected. By applying principal component analysis (PCA), it was pointed out
that crustal soil, biomass and wood burning, secondary atmospheric reactions
involving COVA plant emissions and local soil particles, and traffic were the
main sources contributing to the PM1 measured in the area under study.
Moreover, a possible contribution of the long-range transport of African dust
was observed. |
