“…The environmental risk caused by PAHs was calculated considering the toxicity of individual PAHs. The toxicity equivalence factors (TEFs) of USEPA, [36][37][38], were used for determining the toxicity. The TEFs and risk assessment standards (RASs) recommended in [39] were used in this study.…”

Our study focuses on examining the effects of treated wastewater irrigation (TWWI) on agricultural soils in water-scarce regions, with a specific emphasis on the presence and accumulation of polycyclic aromatic hydrocarbons (PAHs). This issue is particularly significant due to its potential threats to environmental security. During our research, we discovered the existence of 16 different PAHs in these soils, which are known to have harmful impacts on ecosystems and human health. The concentration of total PAHs ranged from 163.9 ng g−1 to 9177.4 ng g−1, with 4- and 5-ring PAHs being the most dominant contributors. The PAHs Fluoranthene and Pyrene were found to be the most prevalent in all soil samples. Comparing the PAH concentrations in our research area to those reported in other studies, we observed that the agricultural areas in our study were more contaminated. Through positive matrix factorization (PMF) and diagnostic ratios (DRs) analyses, we identified petroleum combustion, vehicular emissions, as well as coal, grass, or wood combustion as the primary sources of PAH contamination. We also noted a negative correlation between clay, silt, pH, and PAH concentrations, while a significant positive relationship was observed between total organic carbon (TOC), sand, and PAHs. Based on the computed environmental risk index value, the presence of PAHs in the area poses a moderate to high level of ecological risk. TWWI was identified as the main contributor to PAHs in the agricultural soils we studied. Therefore, it is crucial to establish and enforce standards for wastewater reuse in agricultural fields before irrigation takes place.

“…The coefficient of divergence (COD) is used to identify similarities or differences between pollutant composition profiles [54][55][56]. If the COD values are close to zero, the similarity can be mentioned between the two samples, and if it is close to one (>0.2), the difference and absolute heterogeneity can be mentioned [54,55].…”

“…If the COD values are close to zero, the similarity can be mentioned between the two samples, and if it is close to one (>0.2), the difference and absolute heterogeneity can be mentioned [54,55]. There is also another method used to determine the relationship between two samples and it is known as Spearman's correlation coefficient (R s ) [56]. Higher Rs (>0.7) and a lower COD (<0.2) indicate that the two samples have similar influences from the sources [46,55].…”

Biomonitoring studies have enormous benefits providing a fruitful and cost-efficient means of measuring environmental exposure to toxic chemicals. This study collected ambient air and pine tree components, including needles and 1-year-old and 2-year-old branches, for one year. Concentrations, potential sources and temporal variations of atmospheric polycyclic aromatic hydrocarbons (PAHs) were investigated. In general, lower concentration levels were observed in the warmer months. Ambient PAHs pose a serious public health threat and impose a need for calculating cancer risks. It was also intended to define the best tree component reflecting the ambient air PAHs. The consideration of the representative tree component minimizes the unnecessary laboratory processes and expenses in biomonitoring studies. The coefficient of divergence (COD), diagnostic ratio (DR) and principal component analysis (PCA) were employed to specify the PAH sources. As a result of the DR and PCA evaluations, the effect of the industrial area has emerged, besides the dominance of the pollutants originating from traffic and combustion. The results have shown that pine needles and branches were mainly affected by similar sources, which also influenced air concentrations. Inhalation cancer risk values were also calculated and they varied between 1.64 × 10−6 and 3.02 × 10−5. A potential risk increases in the colder season depending on the ambient air PAH concentrations.

“…[10][11][12] The International Cancer Research Institute of the World Health Organization has declared PHE a class of carcinogen that has been shown to its presence in the human body leads to the damage of monotonous cells by high concentration of free radicals and even risks of amplifying the damage. [13][14][15] In view of the great threats to human health and soil environment caused by PHE, it is of great signicance to study the monitoring of PHE pollutants on soil ecosystem pollution.…”
