Investigation of polycyclic aromatic hydrocarbons in soils from Caserta provincial territory, southern Italy: Spatial distribution, source apportionment, and risk assessment

Heavy metal pollution and human health risk assessment at mercury smelting sites in Wanshan district of Guizhou Province, China

“…The human health risk contribution of each pollution source was quantitatively analyzed by using PMF model, and the mathematical expressions of the quantitative analysis are shown in eqn (5)- (14). 37 The parameter values of each formula referred to the research results of the technical guidelines for risk assessment of soil contamination of land for construction (HJ 25.3-2019) and Li. 38 Table S1 † showed the hazard quotient reference dose and carcinogenic slope factor of the three exposure pathways of each pollutant.…”

Spatial variations, origins, and risk assessments of polycyclic aromatic hydrocarbons in French soils

“…Consequently, soils contaminated by PAHs showed low risks for residential populations, considering that 99% of the soils presented TLCR values under 10 -6 (Table 7). In the literature, higher TLCR values have been identified in southern Italy with mean ILCRs of 4.77 × 10 -6 for adults (Qi et al, 2020)…”

“…Many studies have demonstrated that exposure through food ingestion significantly contributes to the total risk, as in the Yangtze River Delta, where 475 TLCRs rose from 4.4 × 10 -5 to 9.17 × 10 -4 (Wang et al, 2017b). Similarly, in southern Italy, the risk induced by food ingestion exceeded the risks of the other pathways by two orders of magnitude (Qi et al, 2020). Therefore, the potential risks posed by PAHs in French soils could be underestimated, especially since a significant part of the production of cereals (soft wheat and barley) and some vegetables (potato) are cultivated in northern France.…”

Sixteen priority polycyclic aromatic hydrocarbons in roadside soils at traffic light intersections (Bratislava, Slovakia): concentrations, sources and influencing factors

“…Previous studies suggested various conclusions about the influence of soil organic matter on PAH concentrations in urban soils, which are essentially constantly exposed to significant inputs of PAHs from anthropogenic sources. While some authors confirmed a significant positive relationship between PAH concentrations and TOC (Vane et al, 2014;Qi et al, 2020;Yang et al, 2021), others found no correlations (Agarwal, 2009;Liu et al, 2010a). This is explained either by the constant fresh entry of PAHs into the soil causing a sorption disequilibrium between PAHs and TOC or by the more significant influence of black carbons, such as soot and chars, on the sorption of PAHs in urban soils (Agarwal & Bucheli, 2011;Wu et al, 2018).…”

“…It is one of the global human activities that is associated with negative impacts on the environment (Potter & Bailey, 2008), especially in densely populated urban areas (Rodrigue et al, 2009). Polycyclic aromatic hydrocarbons (PAHs) are one of the most widespread groups of organic micro-contaminants present in environmental solid matrices of urban areas (Liu et al, 2010a;Vane et al, 2014;Jiang et al, 2016;Ciarkowska et al, 2019;Ehigbor et al, 2020;Gupta & Kumar, 2020;Konstantinova et al, 2020a;Qi et al, 2020;dos Santos et al, 2021). There are many individual compounds from the PAH group (Wenzl et al, 2006), but the most investigated PAHs in environmental compartments are sixteen PAHs included in the US EPA priority pollutant list (Keith, 2015).…”
