“…In addition, coking is an important industrial sector in Beijing and Tianjin. It is reported that 28 and 39% PAHs in soils of these two cities, Beijing and Tianjin, are derived from coking (Zuo et al 2007;Wang et al 2008). In the meantime, several oil drilling platforms are located in Bohai Bay or its adjacent outer sea.…”

Concentrations, spatial distribution and sources of 16 polycyclic aromatic hydrocarbons (PAHs) listed by the United States Environmental Protection Agency as priority pollutants were investigated in surface sediments of Bohai Bay, North China. Total concentrations of PAHs were in the range of 140.6-300.7 ng/g (dry wt), with an average of 188.0 ng/g. The three predominant PAHs were phenanthrene, acenaphthene and naphthalene. Sedimentary PAH concentrations of the north and central Bohai Bay were higher than those of the southern side of this bay. PAHs source analysis suggested that PAHs in most of the sediments were mainly from grass, wood and coal incomplete combustion. At other stations near the estuaries (Luanhe River Estuary and Chaohe River Estuary) or the oil drilling platform, both petrogenic and pyrogenic inputs were significant. The pyrogenic PAHs close to the oil drilling platform were mainly from petroleum combustion.

“…Formation of specific PAHs is also a temperature dependent process (Peng et al, 2016). 210 Ant, BaAnt, and Chry are often used as tracers of coal combustions (Zheng et al, 2019;Wu et al, 2014;Wang et al, 2009), however, their concentrations in the flue gas of the Longyearbyen PP were negligible. This demonstrates the strong importance of determining indicatory PAH profiles for individual combustion sources for correct source identification.…”

Abstract. Polycyclic aromatic hydrocarbons (PAHs) are not declining in Arctic air despite reductions in their global emissions. In Svalbard, the Longyearbyen coal-fired power plant is considered to be one of the major local source of PAHs. Power plant stack emissions and ambient air samples, collected simultaneously 1 km (UNIS) and 6 km (Adventdalen) transect distance, were analyzed (gaseous and particulate phases separately) for 22 nitro-PAHs, 9 oxy-PAHs and 16 parent PAHs by GC/ECNI/MS and GC-MS/MS. Results confirm low level of PAH emissions (∑16 PAHs = 1.5 µg kg−1 coal) from the power plant. Phenathrene, 9,10-anthraquinone, 9-fluorenone, fluorene, fluoranthene, and pyrene accounted for 85 % of the plant emission (not including naphthalene). A dilution effect was observed for the transect ambient air samples, 1.26 ± 0.16 and 0.63 ± 0.14 ng m−3 sum all 47 PAH derivatives for UNIS and Adventdalen, respectively. The PAH profile was homogeneous for these recipient stations with phenathrene and 9-fluorenone being most abundant. Principal component analysis, in combination with PAH diagnostic ratios and literature data on different source-specific markers, confirmed coal combustion, gasoline, and diesel traffic as the predominant sources of PAHs. Secondary atmospheric formation of 9-nitroanthracene and 2+3-nitrofluoranthene was evaluated and concluded. Results also indicate that ambient PAH concentrations were affected by precipitation events, and specific humidity is an essential parameter influencing PAH scavenging from the air. The present study contributes important data which can be utilized to eliminate uncertainties in model predictions that aim to assess the extent and impacts of Arctic atmospheric contaminants.

“…Kolmogorov-Smirnov (K-S) test was checked for normal distribution, concentrations of PAHs and OCPs were logtransformed to achieve normal distribution for some concentration parameters did not follow a normal distribution, and composition ratio of PCBs at each sample was normalized to the percentage of homologues. Multivariate statistical techniques, such as Factor Analysis (FA) and Cluster Analysis (CA), are powerful tools for distinguishing among the possible sources of observed POPs (Fu et al, 2008b;Jiao et al, 2012;Wang et al, 2009b;Wu et al, 2011;Yuan et al, 2014). The Principal Component Analysis (PCA) with varimax rotation was used for FA to extract components with Eigenvalues greater than 1.…”

“…Previous studies have reported the presence of POP contaminants in the topsoils of urban/suburban Beijing, including Polycyclic Aromatic Hydrocarbons (PAHs) (Li et al, 2006;Liu et al, 2010;Peng et al, 2011Peng et al, , 2012Tang et al, 2005;Wang et al, 2009bWang et al, , 2010, Organochlorine Pesticides (OCPs) (Cheng et al, 2011;Li et al, 2005Li et al, , 2008Shi et al, 2009;Yang et al, 2010) and Polychlorinated Biphenyls (PCBs) (Fu et al, 2008b;Wu et al, 2011). However, few studies have been focused on the behavior of these three groups of POPs at the same time, especially within an industrial area close to a metropolitan area, such as the Yanshan petrochemical area in Beijing, China.…”

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.
