Summary: The research found that both UV irradiation and UV/chlorination processes can significantly reduce the content of PAHs in treated wastewater, with 30 minutes of UV irradiation being the optimal time. However, the mechanisms behind the decrease in PAH content in the process are not clear, and further research is needed to explore this.

Summary: In recent years, there has been significant progress in the study of thermal transformation of waste into valuable materials such as biochar. High-temperature processes can lead to the formation of toxic polycyclic aromatic hydrocarbons (PAHs). However, the pyrolysis process can also result in the formation of derivatives containing oxygen, nitrogen, or sulfur, which may have higher toxicity than parent PAHs. The bioavailability of PAHs is an important parameter in the agricultural application of carbonaceous materials.

Summary: A novel indigenous halotolerant strain, Pseudomonas sp, isolated from petrochemical wastewater in Iran, showed high potential for bisphenol A (BPA) biodegradation. This strain could efficiently degrade BPA at optimal temperature and pH conditions, and also degrade phenol and BPA in salty petrochemical wastewater. Analysis of intermediate metabolites during BPA degradation revealed a possible degradation pathway. Genetic analysis identified the strain as Pseudomonas pseudoalcaligenes.

Summary: Ozone treatment is effective in removing PAHs from waste activated sludge, with removal efficiency increasing with ozone dosage and being highly dependent on pH. The presence of soluble organic compounds, such as proteins and humic substances, can interfere with PAHs degradation during ozonation, highlighting the need for intermittent ozonation for improved removal efficiency.

Summary: The study found microplastics and other anthropogenic microparticles in bivalves from San Francisco Bay, with significant variations in abundance between different sites, and no correlation between the number of microparticles and PAH concentrations. Bivalves may be suitable as bioindicators for microplastic levels in sediment, but not in surface water.

Summary: Petroleum refineries produce oily sludge containing hazardous polycyclic aromatic hydrocarbons (PAH), and its proper disposal is a major concern. Analyzing the physicochemical properties and functions of indigenous microbes at contaminated sites is crucial for determining the bioremediation strategy. This study examines these parameters at two geographically distant sites with different crude oil sources and compares the metabolic capability of soil bacteria based on contamination sources and site age. The results show that petroleum hydrocarbon-derived organic carbon and total nitrogen negatively impact microbial diversity.

Summary: Ozonation is widely used for PAHs removal in waste activated sludge, but the influence of sludge organic matter on PAHs degradation during ozone treatment is still not well understood. This study found that the aromaticity of sludge is positively correlated with PAHs removal efficiency, while the aliphaticity is negatively associated. Additionally, humic acid in sludge matrix has different effects on ozone-based PAHs degradation, with HA-S facilitating removal and HA-D reducing efficiency.

Summary: In this study, a novel wastewater treatment process combining sequencing batch reactor, constructed wetland and microalgal membrane photobioreactor (BCM process) was proposed. The process achieved satisfactory removal of polycyclic aromatic hydrocarbons (PAHs) and their substituted derivatives (SPAHs), and significantly reduced bacterial toxicity and genotoxicity. Microalgae played an important role in ensuring water security.

Summary: This article presents the current knowledge on Canadian PAC emission sources, with forest fires dominating the emissions nationally. Non-industrial sources are estimated to be the second largest contributor, showing moderate decreases in recent decades. Industrial point sources have seen considerable reductions, while fugitive emissions from other industrial sources remain a gap in our understanding. Overall, there is uncertainty in emissions data and regional/local scale examination is needed to determine the sources contributing most to human and ecosystem exposure.

Summary: The comprehensive water quality index (CWQI) is a mathematical statistic that reflects the pollution status of rivers based on several water quality indicators. This study established a CWQI for a typical river in eastern China, using 1-year monitoring data from 20 sampling sets. The predicted CWQI for each monitoring section indicates that most sections are moderately polluted, with some sections being seriously polluted. The analysis shows that TN, n-ary sumation PAHs, and n-ary sumation n-Alks are the main factors influencing water quality, particularly due to the impact of petroleum hydrocarbons in the middle and lower reaches.

Summary: This study evaluated the use of silicone wristbands as passive samplers to assess firefighters' exposures to polycyclic aromatic hydrocarbons (PAHs) during firefighting. The results showed that silicone wristbands could accurately capture exposures to various PAHs, but their effectiveness may be influenced by short sampling time, high temperatures, and high turbulence.

Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater, especially acenaphthene (ACN), has become a major concern due to their potential negative health effects. This study used activated carbon from oil palm leaves to remove ACN from wastewater through adsorption. The optimization of pH, activated carbon dosage, and contact time was conducted using response surface methodology (RSM) combined with central composite design (CCD). The results showed that pH 7, an activated carbon dosage of 2.62 g/L, and a contact time of 71.67 min were the optimal conditions for achieving a removal efficiency of 98.88%. The RSM model was found to be significant, allowing for the prediction and verification of the adsorption results.

Summary: A study conducted in a subtropical rainforest in southern China found that forest canopies play a crucial role in scavenging airborne semi-volatile organic compounds. The study measured polycyclic aromatic hydrocarbons (PAHs) in the understory air, foliage, and litterfall, revealing spatial and temporal variations in PAH concentrations. The research provides important insights into the degradation and accumulation dynamics of PAHs in subtropical rainforests.

Summary: This study measured the oxidative potential of 135 individual PAHs in PM2.5 and found a mismatch between DTT50 results and computed reduction potential values. The GINI equality index correlated with Delta G(rxn) values, indicating a link between electron dispersion and thermodynamic reactions in PAHs. The additive prediction model did not accurately predict the DTT consumption in the assay, suggesting a more complex toxicity model for PAHs in ambient PM2.5.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
