“…Benzo(a)pyrene is considered one of the most carcinogenic PAHs and generally used as an exposure marker for risk assessments (Lee and Vu, 2010). Tong et al (2018) suggested that there is a 45% possibility of carcinogenic risk if PAH exposure exceeds the acceptable threshold (10 −6 ). Significant accumulation and bioavailability of PAHs in the internal organs, which are rich in adipose tissue, after exposure are due to the high lipophilicity (Lee and Vu, 2010;Abdel-Shafy and Mansour, 2016).…”

“…PAHs have ecotoxic effects on aquatic life and birds ( Abdel-Shafy and Mansour, 2016 ). The mode of exposure, exposure duration, and exposure dose are important parameters for the severity of PAHs’ toxic effects ( Rajpara et al, 2017 ; Tong et al, 2018 ). Zheng et al (2018) found that PAHs from different sources showed different risk levels, and they calculated incremental lifetime cancer risk (ILCR) in humans for soil-bound PAHs upon the three different exposure routes; the highest cancer risk was found for ingestion, i.e., 98.1–99.3%, followed by dermal contact, i.e., 0.66–1.83%, and inhalation, i.e., 0.03–0.04%.…”

Polycyclic aromatic hydrocarbons (PAHs) are widespread across the globe mainly due to long-term anthropogenic sources of pollution. The inherent properties of PAHs such as heterocyclic aromatic ring structures, hydrophobicity, and thermostability have made them recalcitrant and highly persistent in the environment. PAH pollutants have been determined to be highly toxic, mutagenic, carcinogenic, teratogenic, and immunotoxicogenic to various life forms. Therefore, this review discusses the primary sources of PAH emissions, exposure routes, and toxic effects on humans, in particular. This review briefly summarizes the physical and chemical PAH remediation approaches such as membrane filtration, soil washing, adsorption, electrokinetic, thermal, oxidation, and photocatalytic treatments. This review provides a detailed systematic compilation of the eco-friendly biological treatment solutions for remediation of PAHs such as microbial remediation approaches using bacteria, archaea, fungi, algae, and co-cultures. In situ and ex situ biological treatments such as land farming, biostimulation, bioaugmentation, phytoremediation, bioreactor, and vermiremediation approaches are discussed in detail, and a summary of the factors affecting and limiting PAH bioremediation is also discussed. An overview of emerging technologies employing multi-process combinatorial treatment approaches is given, and newer concepts on generation of value-added by-products during PAH remediation are highlighted in this review.

“…In addition, they are considered as candidates of persistent organic pollutants (POPs) that merit further investigation for possible early listing in the Stockholm Convention on POPs. Thus, more attention has been paid to PAHs in recent years [11,12,13]. However, there has been less research on the concentration, distribution and possible sources of PAHs in petroleum-contaminated soils, as compared to urban and agricultural soils.…”

The three most representative areas of petroleum pollution on the Loess Plateau are the research subjects of this study. In this study, 16 priority polycyclic aromatic hydrocarbons (PAHs) were determined by the QuEChERS method combined with gas chromatography-tandem mass spectrometry (GC-MS/MS). The total concentrations of ∑16PAHs in top layer soils (0–10 cm), middle layer soils (10–30 cm), and bottom layer soils (30–50 cm) ranged from 1010.67 to 18,068.80, 495.85 to 9868.56 and 213.16 to 12,552.53 μg/kg, with an average of 5502.44, 2296.94 and 2203.88 μg/kg, respectively. The 3-ring and 4-ring PAHs were the most prominent components in all soil samples. Meanwhile, the average value of ∑16PAHs decreased with the depth, from 5502.44 μg/kg (0–10 cm) to 2203.88 μg/kg (30–50 cm). The PAHs levels in the studied soils were heavily polluted (over 1000 μg/kg) according to the Soils Quality Guidelines and 95% of PAHs come from petroleum sources. Moreover, the total of PAHs in petroleum-contaminated soils was assigned a high ecological risk level. Toxic equivalency quantities (TEQs) indicated that PAHs in petroleum-contaminated soils presented relatively high toxicity.

“…PC1 explained 86.5% of the total variance, with high loadings of all individual PAHs except Nap and Ace, and scores of HM-PAHs generally were higher than MM-PAHs. PC1 indicated pyrogenic source, InP and BghiP are related to traffic emission [10,48], the others are considered as markers of coal and biomass combustion. PC2 explained 7.9% of the total variance, with high loadings of volatile PAHs, including Nap (0.50) and Ace (0.81) which are used to originate from coke oven emission [49].…”

The distribution, compositions, sources and ecological risk for polycyclic aromatic hydrocarbons (PAHs) in industrial fields at a large iron and steel enterprise are discussed. Maximum ΣPAHs concentrations in soils of different workshops ranged from 17.50 to 11266.80 mg•kg-1. The ΣPAHs concentrations of the field could classify three categories due to different discharge ways and combustion condition: >1000 mg•kg-1 , 10-1000 mg•kg-1 , <10 mg•kg-1. The spatial distribution of BaP concentration in the coking topsoil was affected by fugitive emissions significantly. Peak values of PAHs occurred in silt lens in 20-30 m depth indicated that pore size radius and conductivity of unsaturated zone played a critical role in the vertical distribution. The strong linear correlation between the multiple organic contaminants indicated that benzene series worked as co-solvents and competitors in unsaturated zone to promote PAHs migration. Nap and Phe were the most abundant compounds in the coking and coal stockyard sites, while Fla, BbF, Pyr, Phe and Chry predominated in other workshops affected by different sources in which coal combustion was the primary source of PAHs. The calculated TEQ of the coking site was found highest and BaP was the most concerning pollutant of the field since the values accounted for 57.8-64.4% of total PAHs in the different workshops.
