Summary: Benzo[a]pyrene (B[a]P) is a representative polycyclic aromatic hydrocarbon (PAH) that is commonly found in the environment and human surroundings. It has been shown to have toxic effects on DNA, reproduction, neurology, and development. The metabolism of B[a]P is mediated by cytochrome P450 (CYP P450) and its polymorphism determines the sensitivity to B[a]P. Additionally, B[a]P may facilitate the replication of viruses.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: The majority of experimental studies on the effects of pollutants on meiofauna have been conducted in closed systems, with the current study revealing that single PAHs impact meiobenthic nematodes similarly in closed or open systems, with higher toxicity observed for benzo[a]pyrene. Closed systems contaminated with PAHs became organically enriched, resulting in changes in the types and numbers of deposit feeders. The responses of taxa to hydrocarbons in open systems were influenced by caudal morphology, with the effects of PAHs mixtures being both additive and synergistic. Based on this study, open systems are preferred over closed systems for more accurate research outcomes.

Summary: In this study, a BaP-degrading strain Pannonibacter sp. JPA3 was isolated from oil well production water, which could remove 80% of BaP at an initial concentration of 100 mg L-1 after 35 days of culture. The metabolites BaP-4,5-dihydrodiol, BaP-4,5-epoxide, 5-hydroxychrysene, and 2-hydroxy-1-naphthoic acid were identified in the biodegradation process. A dioxygenase model was built and molecular docking was performed to investigate the interaction mechanism between BaP and dioxygenase. A hypothesis for the progressive degradation mechanism of BaP by this strain was proposed based on the identification of downstream metabolites. In conclusion, this study provided an efficient BaP degrader and a comprehensive reference for the study of degradation mechanisms at the molecular level.

Summary: This study proposes the use of Cannabis sativa L. for the phytoremediation of PYR-contaminated soil. The results showed that the highest PYR removal rate achieved by hemp was approximately 95%, which was 35% higher compared to the unplanted control. The initial PYR concentration affected the growth and phytoremediation potential of C. sativa L., with lower initial concentrations resulting in higher PYR removal. The interaction between plant roots and rhizosphere microorganisms may play a role in PYR removal.

Summary: This study found that benzo[a]pyrene (B(a)P)-loaded aged polystyrene microplastics (PSMPs) can alter their biological toxicity and increase the risk to human health. The exposure to PSMP@B(a)P exacerbates colon barrier degradation, body weight loss, inflammation, and bacterial translocation. Furthermore, the release of B(a)P from PSMP@B(a)P induced by autophagosome acidification results in the overproduction of reactive oxygen species (ROS), leading to the exacerbation of damage to the tight junction and mucosal barriers.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
