“…The mean concentration of Σ 16 PAHs in soils of the CentralHimalayas region was greater than those in soils of Changbai Mountain and mountains of Western Canada, but less than those in soils of European mountain areas and subtropical Atlantic areas (Ribes et al, 2003a;Choi et al, 2009;Quiroz et al, 2010;Zhao et al, 2015) ( Table S1). Unlike that in other studies conducted in Nepal, the mean concentration of Σ 16 PAHs in soils of Nepal was greater than that in soils of Sagarmatha National Park, but less than that in soils of Kathmandu (Aichner et al, 2007;Guzzella et al, 2011), as well as Agra, Delhi, Kurukshetra, and other cities located in the north of India ( Masih and Taneja, 2006;Agarwal et al, 2009;Kumar et al, 2013). These results indicated that sources of PAHs might be present in the vicinity of the area.…”

“…In this respect, PAH isomer pair ratios have been widely used to elucidate the possible sources. The ratios between low-and high-molecular-weight PAHs (Soclo et al 2000;Xiang et al 2010) and those of specific compounds, such as fluoranthene/(fluoranthene + pyrene), benz[a]anthracene/(benz[a]anthracene + chrysene) (Yu et al 2008;Agarwal et al 2009), phenanthrene/ anthracene, fluoranthene/pyrene, and benzo[a]anthracene/chrysene (Soclo et al 2000;Yunker et al 2002), have been proposed as valuable source indicators. Factor analysis and multilinear regression methods have also been used to identify the sources of particulate matter in the atmosphere (Luo et al 2008;Shen et al 2008;Wang et al 2009).…”

Street dusts collected from 20 locations in the Chang-Zhu-Tan (Changsha, Zhuzhou, and Xiangtan) region, Hunan, China, in May to July 2006, were investigated for sources of polycylic aromatic hydrocarbons (PAHs). The individual PAH concentrations were in the range of 10-4316 ng g(-1), and ∑PAHs(16) levels were in the range of 3,515-24,488 ng g(-1), with a mean of 8,760 ng g(-1). The high-molecular-weight PAHs (four to six rings), ranging from 47.51 to 82.11 %, with a mean of 74.79 %, were the dominant PAH compounds in almost all of the dusts. The isomer ratios suggested a rather uniform mixture of coal combustion and petroleum PAH sources. Factor analysis and multiple linear regression analysis indicate that the main sources of the 16 PAHs were coal combustion/vehicle exhaust, coking/petroleum, and plant combustion, with contribution rates of 50.9, 35.01, and 14.08, respectively. The spatial distributions of PAH concentrations were significantly related to the distribution of industries, traffic circulation, and farmland in this region.

“…The contributions of different PAHs to the TEQ decreased in the order: BaP (62.5%) N DBA (19.2%) N BbF (6.2%) N BaA (4.3%) N InP (3.1%) N BkF (1.6%). The TEQ concentrations were significantly lower than those in soils at a semi-dried area of India (Masih and Taneja, 2006), and also lower than those of agricultural area in Delhi and Shanghai (Agarwal et al, 2009;Jiang et al, 2011a); but higher than those in the soil from unpolluted areas of Spain (Nadal et al, 2004).…”

Thirty-one topsoil samples were collected from the area of the Yanshan petrochemical industries to comprehensively determine the spatial distribution, the possible sources and the potential risks of legacy Persistent Organic Pollutants (POPs) in a typical petrochemical industrial area. The total concentration of 16 PAHs, predominantly originated from the local emission from fuel combustion, ranged from 35.29 to 6120.22 ng/g with a mean value of 906.11 ng/g. Organochlorine Pesticides (OCPs) originated mainly from the recent inputs and their total concentrations varied from 4.13 to 7215.24 ng/g with a mean of 336.13 ng/g. Polychlorinated Biphenyls (PCBs) were associated with the usage of commercial products and the total concentrations of 125 congeners ranged from 2.21 to 4008.47 ng/g with a mean of 486.12 ng/g. Residential Total Lifetime Carcinogenic Risk (TLCR) value, higher than the target excess individual lifetime risk (1 × 10 −6), was calculated to be of 22.6% for PAHs, 16.1% for OCPs and 6. 5% for PCBs respectively. Occupational TLCR, higher than the target excess individual lifetime risk was of 9.7% for PAHs, 6.5% for OCPs and 0% for PCBs respectively. In all sampling sites, non-carcinogenic risks expressed as Total Hazard Quotient (THQ) for PAHs, OCPs and PCBs were always below 1. As a consequence, the carcinogenic and non-carcinogenic risks due to exposure to POPs in soil were very low even in such a typical petrochemical industrial area. In the study, the management and the risk assessment of POPs in a petrochemical industrial area close to a metropolis, were evaluated comprehensively.
