Samples of summer and winter (2010-2011) atmospheric particulate (PM10) of Milan urban area were collected and characterized for some classes of components with health impact.

Toxicity test on pulmonary immortalized cell lines showed different effects produced by summer and winter samples.

Abstract
Samples of summer and winter (2010-2011) atmospheric particulate (PM10) of Milan urban area were collected and characterized for some classes of components with health impact. Moreover, the PM chemical characterization of the main components (i.e. inorganic compounds, organic compounds, and elemental carbon) was performed by XRF and ICP-MS. Toxicity test on pulmonary immortalized cell lines showed different effects produced by summer and winter samples. Indeed, the summer PM10 fraction has a more pronounced inflammatory effect, due to the presence of endotoxins. Nevertheless, their inhibition did not completely vanish the inflammatory effect, which may be related also to both sialic material of crustal source and transition metals . The amount of such materials is significantly higher in the summer PM10. The morphology and chemistry of this fraction components were characterized by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Further analytical transmission electron microscopy (ATEM) investigation will allow to discriminate the mineralogical phases that contribute to the PM10 silicon and transition elements.
