“…Overall, there was an increased potential risk of carcinogenic effects via the dermal exposure route for both adults and children, whereas the inhalation route had the lowest ILCRs for both population groups. Increased potential for cancer risk via dermal exposure compared with ingestion and inhalation for PAHs in soil has also been reported by Xing et al (2020) and Hu et al (2017).…”

“…The PC 1 had high loadings for naphthalene, acenaphthene, acenaphthylene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene, which predominantly indicated PAHs from mixed pyrogenic sources, such as combustion of coal/biomass and refined petroleum products. On the other hand, PC 2 recorded high loadings for pyrene, BbF, BkF, BaP, IP, and DahA, which indicated incomplete combustion, pyrolysis of fuel, and oil burning (Xu et al 2007; Devi et al 2016; Jiang et al 2016; Wang et al 2020; Xing et al 2020).…”

There is an intrinsic link between polycyclic aromatic hydrocarbons (PAHs) accumulated in soils and increased health risk to humans after exposure to contaminated soil via ingestion, inhalation of particulates carrying PAHs, and direct contact with polluted soils. However, the assessment of PAH contamination in most developing countries fails to consider health risk assessment. Therefore, a comprehensive study was conducted to determine the concentration, source, toxicity, and human health risks of 16 PAHs in an urban area in Warri, Delta State, in the Niger Delta region of Nigeria. The results showed varying contamination levels for PAH in soil samples from all sampling points, with benzo[a]anthracene (BaP; at 338.81 μg/kg) being the most abundant at all 9 sampling stations. The highest total concentration of PAH was observed at station 5 (1230.98 μg/kg), which was closest to a flow station. Further comparison with PAH contamination standards showed that soils from stations 1 and 2 were weakly contaminated (<600 μg/kg), and soil samples from stations 3, 4, 6, 7, and 9 were moderately contaminated (<1000 μg/kg). Soil samples from stations 5 and 8 were observed to be heavily contaminated (>1000 μg/kg). The BaP estimates for soil samples obtained for stations 3 to 9 were higher than the BaP soil screening value (15 μg/kg), indicating a carcinogenic potential of soil samples. The results also showed that the incremental lifetime cancer risk estimates for PAH in the soil for adults and children were above the recommended threshold (10 −4) for ingestion and dermal contact, implying that exposure to contaminated soil could lead to cancers in adults and children. Currently, there are no regional or national standards for PAHs in soil that would indicate an increased likelihood for human exposure and subsequent health issues.

“…7,8 PAHs can be produced either by natural or anthropogenic sources, including forest res, volcanic exhalations, diagenesis, industrial emissions, burning of biomass and combustion of fossil fuels, and petroleum spills. [9][10][11] The S 16 PAH contents have been widely reported in global soil, e.g., in London (400-67 000 ng g −1 ), 12 Glasgow (48-51 822 ng g −1 ), 13 Moscow (208-9604 ng g −1 ), 14 Seville (89.5-4004 ng g −1 ), 15 Beijing, China (219-27 825 ng g −1 ), 16 and Delhi, India (81.6-45 017 ng g −1 ). 17 Soil is a major environmental matrix that sustains the lives of all organisms, whether directly or indirectly, and is a major sink for PAHs due to large areas and retention times, resulting in soil quality degradation worldwide.…”

“…The relatively lower weight of children is also a factor contributing to health risks (Hu et al, 2017). PAHs can present carcinogenic risk under the following forms (in descending order): dermal > ingestion > inhalation (Qi et al, 2019;Xing et al, 2020). The predicted risk distribution results show that over 10% of the study area, mainly located in the south of Taiyuan and the north of Linfen, is likely to suffer from high carcinogenic risks for children.…”

Polycyclic aromatic hydrocarbons (PAHs) are widespread in the environment and pose serious threat to the soil ecosystem. In order to better understand the health risks of resident exposed to by PAHs-contaminated soil, 173 surface soil samples were collected in Shanxi Province, China, to detect the levels of 16 priority PAHs. The spatial distribution patterns of PAHs were explored using interpolation and spatial clustering analysis, and the probable sources of soil PAHs were identified for different land-use covers. The results indicate that the soil Σ16 PAH concentration to range from 22.12 to 1337.82 ng g− 1, with a mean of 224.21 ng g− 1. The soils were weakly to moderately contaminated by high molecular weight PAHs (3–5 ring) and the Taiyuan-Linfen Basin was the most polluted areas. In addition, the concentration of soil PAHs on construction land was higher than that on other land-use covers. Key sources of soil PAHs were related to industrial activities dominated by coal burning, coking, and heavy traffic. Based on the exposure risk assessment of PAHs, more than 10% of the area was revealed to be likely to suffer from high child carcinogenic risks. The study maps the high-risk distribution of soil PAHs in Shanxi Province and provides PAH-pollution reduction strategies for policy-makers to prevent adverse health risks to residents.
