Summary: PBDEs are persistent and highly toxic environmental pollutants. In this study, a novel Dehalococcoides mccartyi strain TZ50 was isolated from a PBDE-debrominating enrichment culture, showing the ability to debrominate PBDEs and dechlorinate PCE. The strain expresses RDases that mediate organohalide respiration of both PBDEs and chloroethenes, providing potential for remediation of cocontaminated sites.

Summary: In the flame retardant industry, there has been a trend of using more highly brominated compounds as replacements for banned and regulated compounds. However, there is a lack of knowledge regarding the metabolism and transformation potential of these new compounds. Current research shows variations in experimental protocols and a lack of information on the fate and metabolic pathways of certain environmentally relevant flame retardants. More studies are needed to understand the bioaccumulation and fate of these compounds in exposed organisms.

Summary: Due to widespread production and use of brominated flame retardants (BFRs) in China, their potential impact on human health development should not be underestimated. A review of the literature found that PBDEs and NBFRs enter the aquatic environment through atmospheric deposition, surface runoff, sewage effluent, and microplastic decomposition. The distribution of these compounds in the aquatic environment is highly correlated with local economic structure and population density. Additionally, risk assessment showed high-risk areas are often located in coastal areas with e-waste dismantling sites, mainly due to the historical legacy of electronic waste.

Summary: Improper disposal of e-waste can lead to environmental pollution and human health risks due to the release of high concentrations of PBDEs. However, recycling waste electronic plastics using solvent processes can help reduce these risks. This study focused on the recycling of HIPS from waste TV sets using d-limonene and n-propanol as solvent and precipitant, respectively. The research investigated the relationship between precipitation conditions and the size of precipitate particles, as well as the effect of these conditions on the removal percentage of PBDEs. The results showed that specific conditions, such as lower HIPS concentration, lower precipitation temperature, higher mass ratio of n-propanol to HIPS solution, and greater stirring speed, can promote the formation of smaller and more uniform precipitate particles, thereby improving the removal percentage of PBDEs.

Summary: In this study, trophic transfer of PBDEs and NBFRs was investigated in marine food web in Bohai Sea, China. Significant trophic magnification was observed for certain PBDE congeners, while some NBFRs showed significant trophic dilution. Chemicals with higher K-OW values generally exhibited stronger trophic magnification capacity, but bioavailability could inhibit the trophic magnification ability of superhydrophobic compounds. This study is the first to report on the trophic transfer of NBFRs in marine food web and 9 NBFRs in aquatic food web.

Summary: Polybrominated diphenyl ethers (PBDEs) are widely used fire-retardant chemicals in consumer products and have the potential to bioaccumulate in the environment, including wildlife and humans, leading to adverse health effects such as neurodevelopmental deficits and reproductive dysfunction. In this study, the structural interactions of four PBDEs with the thyroid hormone receptor (TR alpha) were investigated. The results showed that all four PBDEs bound tightly to TR alpha and disrupted the thyroid signaling, which could have implications in reproductive function and infertility.

Summary: Concentration data on POPs in air is necessary to assess the effectiveness of international regulations. However, the low spatial resolution of current monitoring methods limits the understanding of the main sources of POPs in Europe. This study aims to measure the spatial and temporal variability of POPs concentrations with a high resolution and assess the contribution of secondary and primary emissions. The results show that hexachlorobenzene is the most detected POP, with increasing trends and positive correlation with latitude. Other POPs have higher concentrations in the southern part of Europe and declining temporal trends. Model predictions suggest that secondary emissions are more important in controlling atmospheric burdens. The study emphasizes the importance of combining observations and models for policy makers. Rating: 7 out of 10.
