Summary: The interaction between three methoxylated polybrominated diphenyl ethers (MeO-PBDEs) and lysozyme was investigated using computational simulations and multi-spectroscopic methods. The study identified van der Waals and hydrogen bonding forces as major contributors to the interactions, with different binding sites and modes observed for different compounds. These interactions could lead to changes in the lysozyme microenvironment and an increase in alpha-helix structures.

Summary: Halogenated natural products (HNPs) with similar properties to anthropogenic persistent organic pollutants (POPs) were identified in the marine sponge Hyrtios proteus from The Bahamas. Further analysis on octopus from the same area showed similar HNPs. The study indicates that Caribbean marine organisms harbor relatively high concentrations of HNPs.

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: Understanding the self-assembly process of molecules is important for synthetic analogue development and enhancing our understanding of natural systems. Compounds containing crown ethers and pyrene sequences have recently gained attention for their self-assembly capabilities. This study focused on a new molecular system, bis(azopyrenyl) dibenzo-18-crown-6-ether (AzoPy-18C6), and its supramolecular arrangement. Physico-chemical techniques were used for characterization, and Wide-Angle X-ray Diffraction (WAXD) analysis revealed the formation of ordered stacks. Photophysical properties and theoretical calculations further confirmed the molecular interactions within the AzoPy-18C6 system.

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: Polybrominated diphenyl ethers (PBDEs) are listed as persistent organic pollutants (POPs) in the Stockholm Convention. Improper handling and disposal of e-waste in developing countries can lead to PBDE contamination. A study in Nigeria found high levels of PBDE in soil and edible plants near dumpsites, indicating potential risks to the food chain and human health. Better management of end-of-life products containing PBDEs is needed to reduce exposure risk in Africa.

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: 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 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: The study found that specific members of bacterial communities thrive under increasing levels of persistent organic pollutants (POPs) in marine sediments, and that the abundances of certain taxa correlate with specific POPs (or groups), which could potentially be employed in monitoring, status assessment and environmental management purposes.

Summary: In this study, suspect screening was performed to evaluate the presence of dechloranes and their transformation products in Baltic Sea biota. A total of 31 compounds were identified, including dechloranes and their transformation products. Some transformation products had higher concentrations than the parent compounds, with Dechlorane 603 TPs being more than 10 times more abundant. The concentrations of contaminants in the most contaminated species showed little change over a period of 52 years. Most compounds exhibited a slow declining trend in concentrations, while DP and DP-TPs showed an increasing trend. The transformation products showed biomagnification, with similar or higher trophic magnification factors compared to the parent compounds.
