TL;DR: A comprehensive range of gas and particle phase pollutants were sampled at 1-hour time resolution in urban background Milan during summer 2012 as discussed by the authors, and the results show how nitrous acid (HONO) was mainly formed heterogeneously at nighttime, with a dependence of its formation rate on NO2 consistent with observations during the last HONO campaign in Milan in summer 1998, although since 1998 a drop in HONOs levels occurred following to the decrease of its precursors.

TL;DR: In this article, the authors investigated the role of BVOCs in secondary inorganic aerosol (SIA) formation in two periods of EMEP field campaigns, February-March 2009 and June-2006, respectively.

TL;DR: In this article, measurements of O3, NO2, HCHO, H2O2, and hydrocarbons were performed on MetAir's airborne sampling platform in the area of Milan within the Italian Po Basin.

TL;DR: In this article, a multivariate receptor model analysis resulted in the distinction of different characteristic concentration profiles attributed to natural gas, biogenic impact, vehicle exhaust, industrial activities, and a single cyclohexane source.

TL;DR: The results of this study can help to improve urban air pollution modeling in China and Eastern Europe and can be used to constrain a coal burning factor in ambient gas phase positive matrix factorization studies.
