Summary: The study determined the concentrations of 28 novel and legacy PFASs in wastewater from 77 industrial plants in Korea's largest industrial complex. Only 19 and nine target PFASs were detected in untreated industrial wastewater and river water, respectively. Efforts to reduce the use of Perfluorooctane sulfonate (PFOS) have resulted in its replacement by PFASs with fewer than seven carbon atoms in both industrial wastewater and river water.

Summary: It has been found that some PFASs tend to accumulate in the liver and cause hepatotoxicity. Experimental results indicate that there is a competition between liver and blood for the partitioning of PFSAs, which is mainly determined by the competitive binding between hL-FABP and HSA. Therefore, the liver concentrations of PFASs in humans can be predicted from the available serum concentrations, which is important for assessing hepatotoxicity.

Summary: This study provides the first evidence of the deposition of spheroidal carbonaceous particles (SCPs), which are indelible markers of industrialization, in Antarctic ice thousands of kilometers away from potential sources. The earliest observed particle was deposited in an ice layer from 1936 CE. Although deposition fluxes are low, individual SCPs were found to have originated from coal combustion based on chemical analysis.

Summary: This study systematically evaluated the recovery of different lengths of PFAAs using the AOF and EOF methods and found that the EOF method is more suitable for measuring TOF in samples containing ultrashort- and short-chain PFAAs. Decreases in recovery were observed mainly due to losses during the washing step for both methods and incomplete mineralization of perfluoroalkyl sulfonic acids during combustion for the AOF method, as well as incomplete elution of short- and long-chain PFAAs and loss of ultrashort-chain PFAAs during the washing step for the EOF method.

Summary: This study investigated the use of the non-reactive fraction of metals in fingerprinting to estimate historical contributions of suspended particulate matter (SPM) in sediment cores. Results showed that the nonreactive fraction retained more metals in deeper layers, and tributary contributions computed using this fraction were more consistent with historical data and had lower uncertainties. This approach enables robust identification of sub-catchment areas providing large quantities of SPM.

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: Rapid motorization has led to vehicles becoming one of the main sources of air pollution, posing a significant risk to human health. A dynamic vehicle emission model (DVEM) was developed to accurately estimate the spatiotemporal variation and driving factors of vehicle emissions, using polycyclic aromatic hydrocarbons (PAHs) as an example. The results showed that vehicle PAHs emissions peaked in 2012 and declined in the following years due to upgraded emission standards. The emissions varied among provinces in China, with higher levels in eastern coastal provinces. Motorcycles and light duty vehicles were the main contributors to PAHs emissions. Urbanization and urban road density were found to influence the vehicle emission density. Integrated management strategies should be implemented by the government to reduce the impacts of vehicle PAHs emissions.

Summary: Perfluoroalkyl substances (PFASs) in bullfrogs, a popular aquatic food in South China, were found to pose a health risk. However, cooking methods, especially steaming, can effectively reduce PFASs concentrations, while increasing the nutritive value index (NVI). Cultured bullfrogs and steaming were recommended for consumers due to lower PFASs levels and health benefits.

Summary: This study investigated the seasonal variations in microplastic distribution in marine sediments in multiple-used zones of Eastern Guangdong in the South China Sea. It was found that microplastic abundance was lowest in summer, significantly lower than other seasons. The most abundant microplastic size range was 50-200 μm, and transparent and fragmented microplastics were the most frequently observed composition. Microplastic abundance was negatively correlated with distance to the coast. Seaweed ecosystems impacted microplastic abundance by changing the microenvironment and/or direct contact and entrapment. The study also identified the most frequently detected compositions and recommended appropriate management of plastic waste to reduce microplastic pollution in the marine environment.

Summary: In this study, PFAS and fatty acids were tested in squids from the southeast coastal regions of China. Higher concentrations of PFAS were found in squids from the subtropical zone compared to the temperate zone. Cooking methods were effective in reducing PFAS in squids, but caution should be taken to minimize PFAS exposure through juice and oil. Squids can be considered a healthy food due to the health benefits associated with fatty acids.
