Summary: The anthropogenic impact on the aquatic environment of the Rasa River in Croatia was investigated. The study used yellow European eel as a biological indicator to analyze PBDEs, PCBs, DDT isomers, and major and trace elements. The results showed generally low contamination levels in the surrounding area, with organic contaminants increasing in muscle with lipid content, length, weight, and body condition. Metal(loid) levels decreased or remained unchanged with increasing size, except for a few elements that accumulated in the liver at the downstream location.

Summary: Turkey's unique location allows it to receive air masses from Europe, Russia, Middle East, and Africa, making it a significant site for long-range atmospheric transport (LRT) of contaminants. Measurements in Istanbul and Izmir showed high levels of organochlorine pesticides, PCBs, and PBDEs, with DDT and HCH derivatives being dominant species. Temperature dependence indicates contributions from both LRT and local contaminated areas to elevated pollutant levels, with potential source regions identified in Africa, Middle East, Europe, and local metropolitan areas.

Summary: High concentrations of persistent organic pollutants (POPs) in the blood of the Greenlandic population are mainly due to traditional food intake, such as marine mammals and seabirds. This study aimed to investigate the POP concentrations in mothers from the Greenlandic ACCEPT cohort and their relation to lifestyle and diet, while also including the fathers. The results showed higher POP concentrations in fathers compared to mothers, and variations in POP concentrations among different residential towns. Age and fatty acid ratio were positively correlated with most POPs, while the percentage of life lived in Greenland was positively correlated with lipophilic POPs.

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: This study discovered abundant dioxin formation in soil and organic carbon-containing matrices after digestion, with significant correlation observed between Sigma 17PCDD/F concentration and soil organic carbon content. Humic acid was found to be an important component in the conversion of organic matter to PCDD/Fs during digestion. The strong oxidation and production of reactive chlorine by aqua regia were identified as key factors in PCDD/F formation. The annual emission of PCDD/Fs due to digestion with strong acids by the inspection and testing industry was estimated to be 83.8 g TEQ in China in 2021, highlighting the importance of addressing unexpected dioxin formation during digestion processes.

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.
