Atmospheric particulate matter represents one of the most significant environmental problems in urban areas and has urged local authorities to implement traffic restrictions in periods when maximum values have been exceeded.

X-ray fluorescence (XRF) analysis was performed to determine the elements present in the particulate matter using a Rigaku ZSX spectroscope with sequential wavelength dispersion. Chemiometric multivariate analysis (PCA and HCA) was applied to the atmospheric particulate (PM10) considered in this study in an attempt to identify the antropic and/or natural sources that had influence its chemical composition.

Abstract

Atmospheric particulate matter represents one of the most significant environmental problems in urban areas and has urged local authorities to implement traffic restrictions in periods when maximum values have been exceeded. In fact the predominant source of atmospheric pollution in urban areas is attributed to road traffic followed by minor measures from domestic central heating systems and emissions from industrial areas. This study examines results obtained from PM10 collected in the city of Turin during the years 2002, 2003, 2004 and 2005, discusses the concentration of elements (Cl, Fe, Ni, Cr, Cu, Zn, P, S, Mg), expressed in weight, and studies the temporal evolution of these elements during the course of each year. X-ray fluorescence (XRF) analysis was performed to determine the elements present in the particulate matter using a Rigaku ZSX spectroscope with sequential wavelength dispersion. Chemiometric multivariate analysis (PCA and HCA) was applied to the atmospheric particulate (PM10) considered in this study in an attempt to identify the antropic and/or natural sources that had influence its chemical composition.
