“…The carcinogenic risk of skin contact is calculated as follows: (5) where CR dcs is the carcinogenic risk of contaminated soil by skin contact; ca the soil exposure by skin contact (carcinogenic effect); and SF d is the carcinogenic slope factor of skin contact. The soil exposure corresponding to skin contact is calculated using the following formula: (6) The hazard quotient of skin contact is calculated using the following formula:…”

“…In recent years, the ecological and health risks caused by polycyclic aromatic hydrocarbons (PAHs) have become an area of academic focus [1][2][3][4]. PAHs, a class of persistent organic pollutants, are widely distributed in environmental media such as soil, the atmosphere, plants, and water bodies, and are mainly sourced from the incomplete combustion process of fossil fuels and biomass [5,6]. Soil is the most important reservoir for these PAHs, with studies finding that in the UK, 90% of PAHs in the environment are stored in surface soil [7].…”

To obtain a scientific and reasonable health risk assessment of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil from the Guan River Estuary, a probabilistic risk assessment model was used and each parameter's sensitivity was analyzed. The results showed that the total carcinogenic risk (TCR) of PAHs in contaminated soil was 2.46×10 -3 ±2.12×10 -3 , with a maximum value of 1.11×10 -2 and a minimum value of 7.60×10 -4 . All sampling sites exceeded the upper limit value (10 -4 ) of the acceptable carcinogenic risk recommended by the United States Environmental Protection Agency (USEPA), indicating that the carcinogenic risk of PAHs was very high in the contaminated soil of the Guan River Estuary Industrial Area. The total hazard quotient (THQ) was 4.71×10 -1 ±3.90×10 -1 , with the hazard quotient value at most sampling points being lower than 1. Benzo[a]pyrene(B[a]P) and Dibenz[a,h]anthracene(D[ah]A) were the major contributors to the TCR, with contribution rates of 70.57% and 15.61%, respectively; the main contributing monomers to the THQ were Pyrene(Pyr), Fluoranthene(Fl) and Phenanthrene(Phe), with contribution rates of 34.05%, 29.73%, and 17.20% respectively. The sensitivity of B[a]P and D[ah]A to TCR was the highest, reaching 80.28% and 21.58%, respectively. Body weight had a negative sensitivity (−19.15%). Oral intake and skin contact were the main exposure pathways affecting the TCR and THQ, contributing to exposure at rates of 79.74% and 73.28%, respectively.

“…According to the United States Environmental Protection Agency, in 2000, 25% of underground storage tanks for petroleum had leakage which directly resulted in serious groundwater pollution in the United States [6,7]. Toxic and persistent constituents of PHs such as olefinic and paraffinic hydrocarbons, monoaromatic hydrocarbons (e.g., benzene, toluene, and xylene) pose a great threat to human beings [1, [8][9][10]. Hence, developing an economical and effective way to remove PHs from water ecosystems is a major goal to maintain the health of ecosystems and human beings.…”

: The aim of this work was to develop bacterial communities to effectively degrade petroleum hydrocarbons (PHs). We investigated the biotic and abiotic contributors to differences in PHs degradation efficacy between two bacterial strains, Klebsiella pneumoniae (Kp) and Pseudomonas aeruginosa (Pa), screened out from the activated sludge of a petroleum refinery. We characterized the temporal variations in degradation efficacy for diesel and its five major constituents as a sole carbon source and identified more constituents they degraded. The growth characteristics, surface tension, hydrophobicity and emulsifiability of these two strains were measured. We further estimated the relationships between their degradation efficacy and all the biotic and abiotic factors. Results showed that the Pa strain had higher diesel degradation efficacy (58% on Day 14) and utilized more diesel constituents (86%) compared to Kp. Additionally, the growth of the Pa strain in diesel medium was faster than that of the Kp strain. The Pa strain had a lower surface tension and higher hydrophobicity and emulsifiability than Kp, while the surfactant produced by Pa was identified as rhamnolipids. Degradation of PHs was positively related to bacterial growth, hydrophobicity and emulsification but negatively related to surface tension. Overall, differences in degrading capacity for diesel constituents, relative growth rate, and biosurfactant production contributed to the variation in the PHs degradation efficacy of these two bacterial strains.
