Summary: Per- and polyfluoroalkyl substances (PFAS) are widely used in various commercial products and some of them are known to accumulate in aquatic species. A literature search was conducted to understand the relationship between sediments and aquatic species, and data on biota-sediment accumulation factors (BSAFs) for different taxonomic classes were compiled. Among the taxonomic classes, Teleostei had the highest BSAFs, while Magnoliopsida and Bivalvia had the lowest BSAFs. Laboratory-measured BSAFs were consistently higher than field-measured BSAFs.

Summary: The study investigated the taxonomic and trophic responses of meiobenthic organisms, especially marine nematodes, to polybrominated diphenyl ether (BDE-47) in Bizerte lagoon. Results showed significant effects on species abundance and trophic diversity in response to different concentrations of BDE-47. The community of nematodes was separated into different groups based on treatment conditions, with the high concentration leading to dominance of resistant trophic groups.

Summary: This study found the presence of SCCPs in sediments and fish from major rivers in Taiwan, indicating potential sources from human activities and accumulation in sediments. SCCP levels in sediments of 20 major rivers in Taiwan may pose potential ecological risks, but consumption of contaminated river fish showed minimal health risks for most residents, with some concern for health risks in children due to potential bioaccessibility of SCCPs. Routine monitoring of SCCPs in river ecosystems is recommended to protect aquatic organisms and human health.

Summary: This study focused on the thermal treatment of PBDE-contaminated soil, with the optimal conditions determined to be heating at 450 degrees Celsius for 30 minutes with a heating rate of 10 degrees Celsius per minute. Through this method, BDE-209 was successfully removed from the soil to below detection limits, indicating the feasibility of remediating PBDE-contaminated soil through thermal treatment.

Summary: The study investigated the distribution, congener patterns, possible sources, and ecological risks of polybrominated diphenyl ethers (PBDEs) in the surface sediments of 20 fishing ports along the coast of Bohai Sea. The results showed that BDE-209 was the dominant congener and high concentrations of PBDEs were found near Liaohe River, Haihe River, manufacturing plants of BFRs near Laizhou Bay, and tipping areas of marine garbage.

Summary: This study demonstrates that bioaugmentation with Dehalococcoides can accelerate the remediation of pentabrominated diphenyl ethers (PBDEs) in sediments, and the presence of tetrachloroethene (PCE) can improve the bioaugmentation performance. Ecological analysis shows that bioaugmentation leads to more deterministic microbial communities.

Summary: Exposure to PBDEs metabolite PBDEQ induces ROS and mitochondrial dysfunction, promoting NLRP3 inflammasome activation through the TLRs-NF-kappa B signaling pathway. Additionally, bromine metabolism and K+ efflux are involved in the activation of this inflammatory response.

Summary: This study aims to analyze the concentrations of polybrominated diphenyl ethers (PBDEs) in a population of blood donors over a 4-year period and evaluate their temporal trends. The median concentrations of PBDEs showed a downward trend from 2013 to 2014 and then increased after 2014. There were no correlations between age and PBDE congener concentrations, while concentrations were generally lower in females than in males.

Summary: The study utilized a unique method to assess the PBDE content in professional seating furnishing wastes and found that the total PBDE content did not exceed the tolerated threshold. Higher amounts of BDE-209 were identified in hard plastics, but in quantities less than 312 mg kg-1.

Summary: Pseudomonas aeruginosa YH showed efficient degradation of BDE-47 and its intermediates, with transcriptome sequencing revealing significant gene regulation in response to BDE-47 exposure. Inhibition of multidrug efflux pump enhanced bacterial tolerance and degradation of BDE-47, while also accelerating its adsorption.

Summary: A farm in Taoyuan, Taiwan has been contaminated with decabrominated diphenyl ether (BDE-209) for over 10 years, posing a hazardous risk to humans. The study investigates thermal treatment as a method to remove BDE-209 from soil. While heating to 450 degrees C for 30 minutes effectively removes BDE-209, it also reduces soil organic matter, damages microbial biomass, and affects revegetation. By using sugarcane bagasse as an amendment, soil fertility can be restored and bacterial composition improved, making it a promising method for sustainable remediation.

Summary: Hydroxy polybrominated diphenyl ethers (OHPBDEs) interact with thyroid proteins mainly through computational simulation and molecular dynamics, leading to changes in the protein's structure and stability. The observed stronger binding ability of OHPBDEs with thyroxine-binding globulin (TBG) than with transthyretin (TTR) demonstrates the potential impact on endocrine function.

Summary: Polybrominated diphenyl ethers (PBDEs), widely distributed and harmful to human health and wildlife, require sustainable rehabilitation strategies. Although efficient bacteria have been isolated, understanding the external influences and mechanisms on biodegradation is lacking.

Summary: Exposure to PBDEs and metals among rural adult residents along the Yangtze River in China may influence thyroid function, with some PBDE congeners and metals showing associations with thyroid hormones. However, there was no statistically significant association observed between PBDEs, metals, and thyroid-stimulating hormone. Bayesian Kernel Machine Regression analysis suggested similar trends in the relationship between PBDEs, metals mixtures, and thyroid hormones. Additional studies are needed to confirm these findings and identify potential mechanisms.

Summary: The study found that despite all applicators using personal protective equipment (PPE), they still recorded high levels of inhalation exposure to commonly used pesticides. The findings suggest that in addition to observing mandated regular changing and cleaning practices with PPE for ultimate personal protection, pesticide applicators should distance themselves from each other when spraying to effectively reduce their exposure to pesticides from multiple spraying sources.

Summary: A full-scale exercise conducted in Taiwan involving DMATs and USAR teams showed that while the capabilities of each team generally met basic technical standards, compliance rates for certain essential equipment were low. The main barriers to interagency collaboration were found to be differing perspectives and poor mutual understanding.

Summary: Phthalate and SVOCs are widely present in the indoor environment, with the European Commission setting unified test criteria for building products since 2011. A study in Taiwan found that phthalate emissions from floor construction materials vary significantly between normal and high temperatures, suggesting limited volatilization at normal temperatures. This study could serve as a standard for controlling phthalate SVOC emissions in Taiwan's green building material labeling system.

Summary: This study aimed to establish unified standards for Taiwan's Disaster Medical Assistance Teams (DMATs) and evaluate the disaster preparedness of each team. The study found that DMATs have many shortcomings mainly due to the lack of unified government announcement standards, legal protection, and adequate financial support.

Summary: This study assessed the impact of pesticide exposure on the health of children in households of pesticide applicators and non-applicators, revealing significantly higher pesticide concentrations in the homes of non-applicators compared to previously published data. The study suggests showering and changing clothes before returning home as a safety measure to reduce exposure risks.
