Summary: Microwave-assisted extraction was studied to separate tar and residue in coal tar residue (CTR) in order to reduce the content of polycyclic aromatic hydrocarbons (PAHs). Experimental results showed that using a solvent with cyclic structure achieved a high extraction performance and increasing the solvent addition amount, radiation temperature, or radiation time within a certain range improved the extraction efficiency. The optimized conditions were determined as benzene as the extractant, solvent-solid ratio of 5:1 mL/g, radiation temperature of 75 degrees C, and radiation time of 10 min. The relative extraction efficiency of CTR was 28.70% and the reduction efficiency of 16 priority control PAHs was 92.82%. Extracted residue (MCTR) and tar (MCT) can be converted into value-added products (carbon materials, solid fuels, or chemicals) based on their characteristics under the optimum experimental conditions. Microwave-assisted extraction for solid-oil separation is a safe and high-valued utilization approach for CTR.

Summary: The study found high emissions of polycyclic aromatic hydrocarbons (PAHs), especially naphthalene and phenanthrene, in the Wuda coalfield and Suhaitu mining area of northern China, due to coal spontaneous combustion. The PAHs concentration in coal fire sponges reached 17,416 micrograms per kilogram, indicating a significant level of contamination. The results suggest that the content of phenanthrene and naphthalene may serve as a new indicator for identifying coal fire emission sources.

Summary: This study determined the levels of PM2.5, PAHs, and NPAHs in Singapore from 2020 to 2021. The results showed a slightly higher concentration of PM2.5 compared to 2015, while the average PAH concentration decreased during the sampling period. NPAHs were detected for the first time in Singapore, and PAHs and NPAHs were mainly attributed to local vehicle emissions. Air masses from Indonesia and southern China were found to potentially influence the air pollution levels in Singapore.

Summary: The pollution of microplastics (MPs) and polycyclic aromatic hydrocarbons (PAHs) in China's second largest urban lake, East Lake, was investigated. MPs were found to be more abundant in the water than in the sediment, while PAHs were mainly present in 2-3-ring PAHs in water and 4-ring PAHs in sediments. There is a strong correlation between MPs and PAHs, indicating that human activities have a significant impact on the distribution of pollutants.

Summary: The presence of PAHs in parks poses a threat to human health, especially when ingested through different pathways. The environmental quality of parks directly affects the health of both tourists and residents. This study in Urumqi, Northwest China, analyzed PAHs content in park soil and common plants in eight typical parks. Results showed that PAHs content in park soil was 5-6 times higher in the summer compared to the winter, with some samples exceeding the soil pollution risk screening value. Different seasons also affected the PAHs content in plants, with tall arbors having higher PAHs content in the winter and short herbs in the summer. The source of PAHs in plants was more complex during winter. Some parks had higher levels of contamination, and the average lifetime carcinogenic risk for both adults and children reached a low-risk level in the summer, with children having a higher risk than adults.

Summary: Improved analytical methods have allowed the quantification of numerous pesticide transformation products in aquatic environments, yet there is limited understanding of their occurrence and potential toxicity. Through analyzing samples from 442 small streams in urban basins across the United States, it was found that transformation products were detected nearly as frequently as parent pesticides. Detection of these transformation products during baseflow conditions suggests chronic exposure of aquatic organisms and potential groundwater sources.

Summary: Neonicotinoid mixtures are commonly found in streams worldwide, but their ecological impacts are not well understood. This study shows that exposure to neonicotinoids above certain thresholds can lead to a loss in taxa abundance and richness, disrupted adult emergence, and altered trophodynamics. The presence of neonicotinoid mixtures in California streams also poses greater than expected risks to stream health.

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.
