“…Studies to determine the emission sources of PAHs and/or metals have been valuable to characterize the emission of these compounds and to verify the contribution of each source (Dias et al, 2014;Garcia et al, 2014;Martinello et al, 2014;Ribeiro et al, 2014;Hower et al, 2013). Source apportionment studies are important as they serve to identify the more contributing sources for PAHs in ambient air.…”

“…The pellets for the analysis (13 mm diameter) were prepared by mixing 0.300 g of sample and 0.100 g of wax, while keeping them at 100 kN for 120 min. Similar analytical procedures have been reported on previously [32][33][34][35][36][37][38][39][40]. The thermodynamic software package Factsage [41] was used in the equilibrium calculations to identify the chemical species that were thermodynamically most stable in the experimental test conditions.…”

As an important anthropogenic volatile organic compound (VOC), m-xylene has attracted numerous attentions due to its potential in secondary organic aerosol (SOA) formation. In this study, effects of aluminium dust seeds (boehmite and alumina) on SOA yield and aerosol size in m-xylene/NO x photo-oxidation were investigated in a 2 m 3 smog chamber at 30°C and 50% relative humidity. Compared to the seed-free system, the presence of aluminium seeds resulted in an increase in the SOA yield, and also enhanced the O 3 concentration in the chamber. The photolysis of O 3 is a major source of OH radical, which is the most important oxidant of m-xylene. The increase in O 3 concentration could result in the generation of more OH radicals, and finally contribute to the SOA formation. Seed particles influence the SOA size mainly by acting as condensation nuclei. Semi-volatile organic compounds (SVOCs) were condensed onto these nuclei, resulting in the increase in SOA size. However, when aluminium seeds with high concentrations were introduced into the system, SVOCs that had been condensed onto each particle were dispersed by these seeds, leading to the reduction in aerosol size.
