Summary: Polybrominated diphenyl ethers (PBDEs) are widely used flame retardants found in various materials. They have been detected in soil, air, water, dust, and animal tissues, and are associated with a range of toxic effects on different organ systems. Understanding the mechanisms and potential toxicity of PBDEs is important for developing effective prevention strategies.

Summary: The study found that prenatal exposure to background levels of PBDEs, especially BDE-47, was associated with lower IQ scores in boys, but not in girls. This suggests that exposure to PBDEs during early development may have a sex-dependent and detrimental effect on a child's neurodevelopmental trajectory.

Summary: The study investigated PBDE contamination in the microenvironment of family automobiles in Hangzhou City, China. Decabromodiphenyl ether (BDE-209) was found to be the major component, primarily sourced from volatile polyurethanes in seat covers and foot pads. Infants and toddlers were most exposed to PBDEs, with BDE-47 and -99 posing the primary health risks.

Summary: This study found that PBDEs in microplastics can leach upon ingestion, but the leaching kinetics of inherent contaminants from ingested microplastics are poorly understood. Although the bioaccumulation of PBDEs in fish oil can be accelerated in the gastrointestinal tract, the steady-state concentrations of PBDEs in cod tissue lipid through ingestion of microplastics were found to be below the lower end of the global PBDE concentration, suggesting that ingestion of microplastics by organisms remains a negligible pathway.

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: In this study, carbon isotope effects during the photodegradation of PBDEs were investigated using CSIA. Different PBDE congeners exhibited varying debromination trends, with higher fractionation observed for penta-BDEs compared to hexa-BDEs. The normal isotope effects observed support the utility of CSIA for evaluating PBDE photodegradation processes.

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: This study investigates the indirect photolysis and debromination of the organic brominated pollutant decabromodiphenyl ether (BDE209) under visible light irradiation in the presence of humic acid (HA). The results show that HA induces electron transfer and facilitates the activation of C-Br bond via halogen bonds, resulting in the preferential cleavage of meta-C-Br bond. Furthermore, carboxyl group is identified as the key functional group capable of providing oxygen terminals to form halogen bonds.

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 found that the mass concentration of PM10 was higher but the number concentration was lower in the manual dismantling workshop compared to the thermal dismantling workshop. The gaseous phase PBDE concentration was higher in the manual dismantling workshop while the particulate phase PBDE concentration was higher in the thermal dismantling workshop. The size distribution of particles was similar between the two workshops, but there were significant differences in the distribution of particle-bound PBDE.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. 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.

Summary: Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Little is known about microbial community resistance and adaptation to disturbances, hindering our understanding of recovery latency and implications for ecosystem functioning. This study found that anthropic disturbance and natural disturbance have different effects on the topology and stability of soil microbial networks.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. 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.
