“…PAHs markers are powerful to identify and attribute emission sources (Mancilla et al, 2016). Typical PAH markers were Chr, BkF, Flu, Pyr, BaA and BaP for coal burning (Bourotte et al, 2005;Ravindra et al, 2008;Teixeira et al, 2015); Acy, Ant, Phe, Flu, Pyr,…”

We summed the concentrations of these markers and adjusted to PM2.5 mass concentration for each source type of the two periods.…”

Under great efforts in fighting against serious haze problem of China since 2013, decreasing of air pollutants especially for fine particles (PM) has been revealed for several key regions. This study tried to answer whether the reduction of PM-bound polycyclic aromatic hydrocarbons (PAHs) was coincident with PM because of long-term pollution control measures (PCM), and to assess source-oriented health risks associated with inhalation exposure to PAHs. Field measurements were carried out before and after the publishing of local air pollution protection plan for Nanjing, a mega-city in east China. Results indicated that the air quality was substantially improving, with a significant reduction in annual average PM by 34%, and moreover, PM-bound PAHs significantly reduced by 63% (p < 0.001). The remarkable reduction was mainly attributable to the change of emission sources, compared to the influence of atmospheric circulation patterns, surface meteorological conditions, and atmospheric chemical reaction. Four PAHs sources including coal combustion (CC), petroleum and oil burning (PO), wood burning (WB) and vehicle emission (VE) were identified. On an annual basis, contributions to ambient PM-PAHs from WB, PO, CC and VE sources in the period before the action of control measures were 2.26, 2.20, 1.96 and 5.62 ng m, respectively. They reduced to 1.09, 0.37, 1.31 and 1.77 ng m for the four source types, with the reduction percentages as 51, 83, 33 and 68%, respectively. The estimated reduction in lifetime lung cancer risk was around 61%. The study that firstly assessed the health effects of PAHs reduction as a co-benefit raised by air PCM sustained for a long period is believed to be applicable and referential for other mega-cities around the world for assessing the benefits of PCM.

“…The most commonly applied techniques including Chemical Mass Balance (CMB) (Yang and Chen, 2004), Principle Component Analysis (PCA) (Dong and Lee, 2009; Li et al, 2006; Ma et al, 2011; Mai et al, 2003; McDonough et al, 2014; Mishra et al, 2016), Positive Matrix Factorization (PMF) (Callen et al, 2014; Xie et al, 2014), and multilinear regression (Harrison et al, 1996; Masiol et al, 2012). Comparison studies showed that these receptor-oriented methods generally give comparable PAH source apportionment results (Larsen and Baker, 2003; Teixeira et al, 2015). In addition, some studies used carbon isotope dating to differentiate contributions from biomass burning to fossil fuel combustion (Mandalakis et al, 2005; Sheesley et al, 2009; Zencak et al, 2007).…”

A revised Community Multiscale Air Quality (CMAQ) model was developed to simulate the emission, reactions, transport, deposition and gas-to-particle partitioning processes of 16 priority polycyclic aromatic hydrocarbons (PAHs), as described in Part I of the two-part series. The updated CMAQ model was applied in this study to quantify the contributions of different emission sources to the predicted PAH concentrations and excess cancer risk in the United States (US) in 2011. The cancer risk in the continental US due to inhalation exposure of outdoor naphthalene (NAPH) and seven larger carcinogenic PAHs (cPAHs) was predicted to be significant. The incremental lifetime cancer risk (ILCR) exceeds 1 × 10−5 in many urban and industrial areas. Exposure to PAHs was estimated to result in 5704 (608–10,800) excess lifetime cancer cases. Point sources not related with energy generation and the oil and gas processes account for approximately 31% of the excess cancer cases, followed by non-road engines with 18.6% contributions. Contributions of residential wood combustion (16.2%) are similar to that of transportation-related sources (mostly motor vehicles with small contributions from railway and marine vessels; 13.4%). The oil and gas industry emissions, although large contributors to high concentrations of cPAHs regionally, are only responsible of 4.3% of the excess cancer cases, which is similar to the contributions of non-US sources (6.8%) and non-point sources (7.2%). The power generation units pose the most minimal impact on excess cancer risk, with contributions of approximately 2.3%.

“…Polycyclic aromatic hydrocarbons (PAHs) are some of the most dangerous contaminating pollutants in the environment . The presence of these pollutants in the environment results from the incomplete combustion of organic matter . They enter into the surface water by atmospheric fallout, leaching of municipal effluents, vehicle emission, and by oil spills .…”

Polyaniline coated cigarette filters were successfully synthesized and used as a solid-phase extraction sorbent for the extraction and preconcentration of polycyclic aromatic hydrocarbons in water samples. The polyaniline helped to enhance the adsorption ability of polycyclic aromatic hydrocarbons on the sorbent through π-π interactions. The high porosity and large surface area of the cigarette filters helped to reduce backpressure and can be operated with high sample flow rate without loss of extraction efficiency. The developed sorbent was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The parameters that affected the extraction efficiencies, i.e. polymerization time, type of desorption solvent and its volume, sample flow rate, sample volume, sample pH, ionic strength, and organic modifier were investigated. Under the optimal conditions, the method was linear over the range of 0.5-10 μg/L and a detection limit of 0.5 ng/L. This simple, rapid, and cost-effective method was successfully applied to the preconcentration of polycyclic aromatic hydrocarbons from water samples. The developed method provided a high enrichment factor with good extraction efficiency (85-98%) and a relative standard deviation <10%.
