Distribution and characterization of polycyclic aromatic hydrocarbon compounds in airborne particulates of east asia

This study was carried out between January and February 2013, at two sites in the city of Cuernavaca, México, using low-volume equipment. Fifteen Polycyclic aromatic hydrocarbons (PAHs), were identified by gas chromatography coupled with mass spectrometry. The total average concentration observed for PAHs was 24.0 ng·m −3 , with the high molecular weight compounds being the most abundant. The estimated equivalent concentration for Benzo (a) P (BaPE) was 4.05 ng·m −3 . Diagnostic ratios together with the principal components analysis (PCA) allowed for establishing coal burning and vehicle OPEN ACCESSAtmosphere 2015, 6 1260 emissions as being the main sources of these compounds in the area. The PAHs used to calculate this index account for 51% of the 15 PAHs identified, which probably involves a risk to the exposed population.

“…PAHs are produced by incomplete combustion and pyrolysis of fossil fuels such as oil and coal, and from other organic materials from natural and anthropogenic sources [4][5][6], including vehicle emissions, wood burning, waste incineration, coke production, and metal production [7][8][9].…”

“…PAHs are products of incomplete combustion and pyrolysis of fossil fuels such as petroleum and coal and other organic materials from natural and anthropogenic sources [3][4][5][6][7][8][9][10][11][12][13] including fossil fuels combustion [14], vehicle exhaust [15,16], open-fire straw burning [16,17], cigarette smoking [17], wood combustion [18], industrial production [19], including waste incineration [6], metal production [20], coke production [20], iron production [5,17], airplane production [17], etc. Results of previous studies had shown that the main sources of PAHs in urban area were traffic exhaust (diesel or gasoline) and certain industrial processes [20,21].…”

“…The dense traffic, industrial activities, daily cooking, and winter heating of urban residents emit considerable amounts of PAHs into the urban environment (Heywood et al 2006;Liu et al 2006). PAHs are lipophilic chemicals that are prone to adsorb onto soil particles.…”

We investigated the sources, distribution, and health risks of polycyclic aromatic hydrocarbons (PAHs) in soils of peri-urban Beijing. The mean concentrations of total 16 PAHs in suburban and rural soils of Beijing were 321.8 ± 408.2 and 219.2 ± 233.5 ng/g, respectively. The PAH concentrations decreased along the urban-suburban-rural gradient and varied with land use categories. The industrial areas had the highest soil PAH concentrations followed by the living areas, roadsides, green areas, and agricultural areas. The major sources of PAHs in these soils were coal and biomass combustion. Traffic emission was not the dominant source of PAHs in peri-urban Beijing. At a few sites, high soil PAH contents were caused by point sources such as iron and steel plants and a wood preservative factory. The incremental lifetime cancer risks (ILCRs) of adults and children exposed to PAHs in the soils were acceptable. However, cautions should be paid to the abandoned industrial sites, which might be converted to residential area during the urbanization process.
