Modelling evaluation of emission scenario impact in northern Italy

Abstract

In this work, the multiphase model TCAM has been applied to evaluate the impact of three different emission scenarios on PM10 concentrations in northern Italy. This domain, due to high industrial and residential site, to a close road net and to frequently stagnating meteorological conditions, is often affected by severe PM10 levels, far from the European standard laws. The impact evaluation has been performed in terms of both yearly mean value and 50 μg/m3 exceedance days in 9 points of the domain, chosen to be representative for the chemical and meteorological regimes of the domain. The results show that all the three emission reduction scenarios improve air quality all over the domain, and in particular in the area with higher emission density. © 2008 Springer.
