“…where CS is the sum of BaP equivalent concentration (BaPeq) (µg kg -1 ), BaPeq is the product of the concentration of individual PAH compound and its corresponding toxic equivalence factor (TEFs) ( Table 2) (Tsai et al, 2004;Chen et al, 2014;Tiwari et al, 2015) ) Qin et al, 2015). The carcinogenic slope factor (SCF) based on the cancercausing ability of BaP were addressed as 7.30, 25 and 3.85 (mg -1 kg -1 d -1 ) -1 for ingestion, dermal contact and inhalation, respectively .…”

Twenty-two street dust samples collected from a small steel city, central China, were analyzed for 16 USEPA priority PAHs to investigate the concentration, spatial distribution relationship with black carbon (BC) and Iron (Fe), and the source apportionment and to assess the health risk of these compounds. The mean contents of PAHs, BC and Fe were 4.43 µg g -1 , 12837.97 mg kg -1 , 70205.70 mg kg -1 , respectively. The highest spot was in the surrounding of the E'zhou Steel Plant and the Steel Rolling Mill of E'zhou. The correlation analysis indicated that there was no obvious relationship between Fe with each other, the PAHs significantly correlated to black carbon (BC), which might be caused by the continuous emission sources of iron and steel production. The results of sources identification suggested that PAHs contaminations in street dust were a mixed source of industrial production and traffic emission combustion. The incremental lifetime and cancer risks (ILCRs) of exposing to PAHs in the street dust of the E'zhou city for the three age groups (namely childhood, adolescence, adulthood) fluctuated with in the range of 10 -6 to 10 -4 , indicating a potential of carcinogenic risk for exposed populations.

“…The major sources of PAHs are heating (coal, oil, gas and wood), petroleum refinery, coke production, fossil fuel combustion, industrial processes, steel and iron furnaces, incinerators, and vehicles (Chen et al, 2014;Li et al, 2014b;Huang et al, 2015;Mwangi et al, 2015a;b;Qin et al, 2015). Since several PAHs have been classified as human carcinogens (groups 2B, 2A and 1) by the International Agency for Research on Cancer (IARC, 1987;Kamal et al, 2016), public concern with the release of these carcinogenic pollutants in the global environment has recently increased.…”

The chemical mass balance model was applied to estimate the major sources of atmospheric polycyclic aromatic hydrocarbons (PAHs) at an Industrial Region in Kaohsiung, Taiwan. The gaseous and particulate phases of 16 individual compounds were analyzed between March 2012 and August 2012. The mean total concentrations and total BaP eq were higher during the cold season and lower during the warm summer, with gaseous PAHs predominant at all sites. Low weight-PAHs and median weight-PAHs were found predominantly in the gaseous phase, while high weight-PAHs were predominant in the particle phase. Results from the receptor model revealed that the average contributions were 38.2%, 27.2%, 20.7%, 6.8%, 5.2%, and 2.0% from vehicles, heavy oil combustion, natural gas combustion, incinerator, tetrabromobisphenol A production, and diesel combustion at the seven receptors, respectively. Vehicle emissions appear to be the significant source of PAHs in the investigated area, although other industrial sources, as described above, also have an impact on the total PAHs.

“…PAHs both in gas and particle phase can emitted to the environment from natural processes such as incomplete combustion of organic matters, volcanic eruptions and forest res (Wang et al 2008). However, in urban and industrial areas, these compounds are formed mainly through incomplete combustion of fossil fuels (Luo et al 2019;Qin et al 2015;Huang et al 2015;Mostert et al 2010;Lai et al 2017). Due to adverse health effects, PAHs have attracted considerable attention by researchers and are considered as priority pollutants (US EPA 2010; Wang et al 2020aWang et al , 2017.…”

Particulate matters (PMs) and their associated chemical compounds such as polycyclic aromatic hydrocarbons (PAHs) are important factors to evaluate air pollution and its health impacts particularly in developing countries. Source identification of these compounds can be used for air quality management. The aim of this study was to identify the sources of PM2.5-bound PAHs in Isfahan city, a metropolitan and industrialized area in central Iran. The PM2.5 samples were collected at 50 sites during one year. Source identification and apportionment of PAHs were carried out using diagnostic ratios (DRs) of PAHs and positive matrix factorization (PMF) model. The results showed that the concentrations of PM2.5 ranged from 8 to 291 µg/m3 with an average of 60.2 ± 53.9 µg/m3 whereas the sum of concentrations of the 19 PAH compounds (ƩPAHs) ranged from 0.3 to 61.4 ng/m3 with an average of 4.65 ± 8.54 ng/m3. The PAH compounds showed their highest and lowest concentrations in fall and summer, respectively. Applying DRs, suggested that the source of the PAHs were mainly from fuel combustion. The main sources identified by the PMF model were gasoline combustion (28 %) followed by diesel combustion (22 %), natural gas combustion (17 %), evaporative-uncombusted (13 %), industrial activities (11 %), and unknown sources (9 %). The results revealed that in addition to transportation and industrial activities, combustion of natural gas for heating systems as one of the PAHs source in PM2.5 should be managed in the metropolitan area.
