Summary: This study investigated the occurrence, distribution, bioaccumulation and ecological risk of organic ultraviolet absorbers (OUVAs) in coral reef regions in the South China Sea. The results showed that OUVAs were lower in offshore seawater and corals compared to coastal areas, possibly due to higher human activities. Additionally, offshore corals exhibited higher bioaccumulation capability of OUVAs and BP-3 posed bleaching risks to both coastal and offshore corals. The management and control of BP-3 usage and discharge is crucial for coral reef protection in the South China Sea.

Summary: Knowledge on bioaccumulation and trophic transfer in food webs is crucial in evaluating contaminant hazards. This study investigated the presence of PFAAs in organisms sampled from Qinzhou Bay in the South China Sea, and found different distribution patterns between short-chain and long-chain PFAAs based on trophic positions. Results suggest a potential biomagnification effect of PFOS, while the effects of PFOA were less clear. Banned long-chain PFAAs were found to still persist in the coastal marine ecosystem, while emerging short-chain PFAAs showed high concentrations but no biomagnification.

Summary: High-latitude coral communities have the potential to serve as refuges during global climate change, but this is being hindered by the combined pressure of global climate and anthropogenic activities. A long-term monitoring study on coral communities along the Bailong Peninsula in the northern South China Sea revealed that corals have a scattered and uneven distribution pattern, but the growth of reef-building corals and coral recruitment are improving, which play important roles in regulating the structure of adult coral populations and promoting the development of coral communities. The Bailong Peninsula has the potential to become a refuge for corals if human activities impacting coral restoration potential are controlled.

Summary: Seafood consumption is more frequent among Asians compared to other ethnic groups in the U.S., but there is little information about how culturally specific fish consumption contributes to exposure to toxicants. This study surveyed fish consumption among Chinese, Korean, and Vietnamese communities in Chicago and analyzed 103 seafood samples for mercury and organic chemicals. The research found that certain types of fish, such as bluefish, pike, and tuna steak, had high mercury levels, while octopus, shrimp, and tilapia were the least contaminated. Omega-3 fatty acids were more associated with organic contaminants than mercury. Consumption limitations were identified for seven types of fish based on risk assessment.

Summary: Per- and polyfluoroalkyl substances (PFASs) have gained attention for their persistence, bioaccumulation, and toxicity. Various activated carbons (ACs) show variability in adsorptive performance towards PFASs. This study comprehensively investigates the adsorption of ten PFASs on different ACs to understand their removal mechanism. Results indicate that GAC-1 and PAC-1 remove over 90% of all target PFASs, and the adsorption mechanisms involve electrostatic interaction, hydrophobic interaction, surface complexation, and hydrogen bonding.

Summary: This study systematically investigated the adsorptive removal of 10 PFASs by four anion-exchange resins. The results showed that the capacities of resins absorbing PFASs varied, with gel strong base HPR4700, macroreticular strong base S6368, and macroreticular weak base A111S showing higher capabilities compared to gel weak base WA10. The presence of fulvic acid and inorganic anions hindered the PFAS removal, with WA10 being the most affected. HPR4700, S6368, and A111S were more effective in removing PFASs under neutral and alkaline conditions, while WA10 was not able to remove PFASs under alkaline medium. This study provides theoretical support for the removal of PFASs from aqueous phases using different resins.

Summary: This review focuses on the properties and fate of polar organic pollutants in natural waters and engineered aquatic systems. It discusses the occurrence and treatment efficiencies of various compound groups, including PFAS, pesticides, PPCPs, and other compounds. The review also presents a new approach to characterizing mobile compounds based on their basic properties and provides insights into the current status and research needs of aquatic and multimedia models. The findings suggest that many pharmaceuticals and endocrine disruptors can be effectively removed from water through sorption, chemical oxidation, photolysis, and biodegradation. Additionally, sediment core profiles may not accurately reflect the chronological production and use of polar organics due to post-depositional mobility of water-soluble compounds. The review proposes a novel method for identifying mobile compounds using sediment records, and highlights the development of models for PFAS, insecticides, fungicides, atrazine, and pharmaceuticals.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. 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.
