Summary: Understanding the potential source and ecological risk of polycyclic aromatic compounds (PACs) in lakes is crucial for the safety of the aquatic environment. Sedimentary samples were collected from Lake Taihu, China, and analyzed for various PACs. The distribution of PACs in sediments was influenced by economic development, transportation, and organic carbon content. The integrated approach of diagnostic ratios, principal component analysis-multiple linear regression (PCA-MLR), and positive matrix factorization (PMF) was used to identify the sources of PACs.

Summary: Ecological regime shifts in China's largest lagoon, Lagoon Pinqing, have influenced the contribution of microplastics to the burial of polycyclic aromatic hydrocarbons (PAHs) in sediments. The contribution varied during different periods due to changes in factors such as total phosphorus and total nitrogen. The results suggest that regime shifts can enhance the contribution of microplastics to the burial of PAHs, with the degree of contribution influenced by the specific regime shift.

Summary: The study conducted in CanGio wetland of Hochiminh City, Vietnam revealed wide variation in total PAHs in surface sediments, with similar patterns observed in other estuaries and coastal areas. A decreasing trend of PAHs in the wet season was attributed to inland sources such as wastewater discharge and atmospherically transported contaminants, posing a negligible risk in the coastal and estuarine areas of CGW. This study provides baseline data for regular monitoring and future environmental protection strategies in the study area.

Summary: This study investigated the distribution, sources, and ecological risk of 43 compounds of polycyclic aromatic hydrocarbons (PAHs) in the surficial sediments of the Persian Gulf. The results showed that the calculated total toxicity of PAHs in all stations in the Persian Gulf was below the lethal level for benthic organisms, while there was a risk of toxicity for benthic organisms in the Gulf of Oman. Nitrogenated and oxygenated derivatives did not pose a significant risk in the study area. Based on diagnostic ratios and source identification analysis, mixed sources (both petrogenic and pyrogenic) and pyrogenic sources were identified as the main sources of PAHs.

Summary: This study investigated the spatiotemporal distribution, source, and ecological risk of PAHs and SPAHs in surface sediments in Laizhou Bay. The results showed seasonal differences in concentrations of PAHs and SPAHs and a spatial distribution trend of estuary > coast > offshore. Combustion sources, including petroleum, coal, and biomass, were identified as the main contributors to PAHs and SPAHs. The risk level of PAHs was low-to-moderate, while SPAHs posed a moderate-to-high ecological risk.

Summary: This study analyzed the concentration of PAHs in sediment cores from the Tibetan Plateau and found that PAHs primarily come from biomass and coal combustion. The deposition history of PAHs in the sediment experienced periods of stability, increase, and decline. Organic carbon was identified as a key factor influencing the concentration of PAHs. The ecological risk assessment showed a low risk level of PAHs in the Tibetan Plateau sediments.

Summary: This study investigated the distribution, sources, ecological/health risks, and the impact of regional economic variations on polycyclic aromatic hydrocarbons (PAHs) contaminations along the coast of the Yellow Sea in China. Sediments from a broad coastal coverage were collected and analyzed, showing a total content of 16 priority PAHs ranging from 1.4 to 1675.9 ng/g with an average value of 295.7 ng/g, except for a higher value in the site adjacent to Qingdao City. Source analysis indicated that PAHs were mainly from pyrolytic sources, with smaller contributions from petroleum spills and combustion. Risk assessment suggested negligible biological and health risks in most areas along the Yellow Sea coast.

Summary: The study investigated historical polycyclic aromatic hydrocarbon (PAH) pollution through sedimentary records in three lakes in China. The results showed that PAH concentrations in sediment are still increasing in these lakes, showing a different trend compared to developed countries. The PAH pollution in South China started earlier in 1850, while the increases in North and Northeast China were observed from 1980. The PAH concentrations were highly correlated with local economic development. The study also identified the main sources of PAHs in lake sediments, including oil leaks, coal and biomass combustion, vehicle emissions, and diagenesis. The findings of this study provide important information for understanding and controlling PAH pollution.

Summary: This study reports the occurrence, fates, and carcinogenic risks of SPAHs and PAHs in two coking wastewater treatment plants, revealing that biological treatment processes effectively remove MPAHs, OPAHs, and NPAHs. Transformation and adsorption were identified as major mechanisms for removing different types of PAHs and SPAHs. Concerns were raised over the relatively high concentrations of SPAHs in excess sludge and treated effluent, as well as the potential lung cancer risks posed by the presence of SPAHs in the ambient air.

Summary: This study provides a high-spatial-resolution analysis on the distributions, characteristics, and environmental risks of microplastics in the southern East China Sea. The results show that microplastics are commonly found in surface sediments, with higher concentrations near urban centers. The dominant types of microplastics are polyethylene and polyethylene terephthalate, mainly in the form of fibers and fragments, and have a size of 0.1-0.5 mm. The study highlights the complex interactions among physical, biological, and topographic factors that control the distribution and environmental risks of microplastics in coastal sediments.

Summary: In this study, a solid superacid catalyst (SO42-/ZrO2) was used to upgrade bio-oil through hydrothermal liquefaction (HTL) of algae. The catalyst was found to significantly adjust the composition of the bio-oil and improve its higher heating values (HHVs). The catalytic performance could be regulated by adjusting the acid amount and acid strength of SO42-/ZrO2. Additionally, the catalytic effects of the catalyst on major components of algae were explored, showing increased yields of bio-oil from proteins and lipids and the prevention of the Maillard reaction between polysaccharides and proteins.

Summary: The Shiweidong W-Cu deposit in China is a quartz vein type W-Cu deposit located in the Dahutang W-Cu ore field. It is characterized by the presence of economically valuable W and Cu minerals, with resources of 0.3 Mt WO3 and 0.24 Mt Cu. The origin and characteristics of the W and Cu mineralizing fluids are still debated. In this study, fluid inclusions were analyzed to determine the homogenization temperature and salinity, and trace element compositions were used to clarify the fluid characteristics responsible for W and Cu mineralization. The results indicate that W and Cu mineralization in Shiweidong was introduced by distinct fluids.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
