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 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: Polybrominated diphenyl ethers (PBDEs) are a type of brominated flame-retardants (BFRs) that are mainly introduced to the human body through dietary intake. This review discusses recent studies conducted from 2012 to 2022, which show a general trend of decreasing levels of PBDEs in food and consequently, a decrease in dietary intake. The lack of tolerable daily intakes of PBDEs remains a challenge for assessing the human health risks associated with these compounds.

Summary: Polybrominated diphenyl ethers (PBDEs) are important pollutants during e-waste dismantling activities in China. Bromophenols (BPs), which are flame retardants and metabolites of PBDEs, are often overlooked in assessing human exposure to e-waste. Analysis of serum, hair, and urine samples showed higher frequencies of PBDE and BP detection in hair. Although levels of EPBDEs and EBPs were significantly higher in the hair of occupational populations, no significant difference was found in serum and urine levels between occupational and non-occupational populations. The study suggests that hair analysis can better differentiate the exposure intensities of PBDEs and BPs.

Summary: The study investigated the effects of polybrominated diphenyl ethers (PBDEs) and tris(2-chloroethyl) phosphate (TCEP) on thyrocytes. PBDEs demonstrated genotoxicity but not cytotoxicity in follicular thyrocytes in vitro. These findings suggest that PBDEs may have carcinogenic potential in human thyroid cells.

Summary: This study measured the levels of 7 PBDE congeners and 11 PAHs in dust samples collected in kindergartens, workplaces, and cars in Zagreb, Croatia. The results showed a potential risk, especially for professional drivers, with PBDEs mass fractions ranging from 3.11-14.42. Toddlers are also more susceptible to higher risk despite spending less time in cars.

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: 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: Data collected from a birth cohort in New York City revealed that prenatal PBDE exposures were not associated with child growth trajectories in Dominican and African American children. The study found no significant impact of cord levels of individual PBDEs or total PBDE mixture on childhood BMIz. Adjusting for postnatal PBDE exposures did not alter the results.

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: Nonradical-based advanced oxidation processes show great promise in pollutant removal due to their superior characteristics. In this study, carbon nitride-based cuprous catalysts were found to effectively activate peroxydisulfate for the degradation of Tetrabromobisphenol A. The primary ROS in the system was unveiled to be singlet oxygen generated from superoxide anions and dissolved oxygen. This study provides insights into the mechanism of PDS activation by carbon nitride-based cuprous catalysts and offers an innovative catalytic system for in situ chemical oxidation.

Summary: Peroxymonosulfate-assisted advanced oxidation processes (PMS-AOPs) catalyzed by single-atom catalysts have been developed for the degradation of bisphenol A (BPA) using cobalt single-atom catalysts supported by graphitic carbon nitride (SA-CoCN). The study revealed that high-valent cobalt [Co(IV)] and singlet oxygen (O-1(2)) were the main reactive species for pollutant degradation under acidic and alkaline conditions, rather than the commonly accepted free radicals (SO4 center dot- and center dot OH).

Summary: This study compared the morphology and surface characteristics of different MxMn3-xO4 nanoparticles and their catalytic performance for PMS activation to degrade TCE. The results showed that cubic spinel catalysts exhibited higher catalytic activity and TCE removal efficiency compared to tetragonal spinel catalysts. The nanoparticles also demonstrated reusability and a wide applicable pH range. Free radical scavenging experiments and EPR analysis confirmed the importance of free radicals generated by cubic spinels in TCE removal.

Summary: This study revealed the mechanisms of inactivation and photoreactivation of the super-resistant bacterium Acinetobacter sp. CS-2 by UV, chlorination, and UV/chlorination disinfection. CS-2 showed certain photoreactivation after UV and chlorination treatment. UV/chlorination resulted in high-efficiency reduction of CS-2 and effectively controlled its photoreactivation. Compared with UV disinfection, UV/chlorination caused irreversible destruction to bacterial surface structures, leading to better disinfection efficacy. The singlet oxygen (1O2) generated during UV/chlorination treatment played a vital role in the removal of the blaNDM-1 gene.

Summary: This study evaluated the neurotoxicity of lifetime exposure to an environmentally relevant concentration of BP3 in zebrafish. The results showed that continuous BP3 exposure led to female-biased social behavioral deficits and learning and memory impairment. These effects were accompanied by changes in brain weight, dopamine concentration, neurogenesis, apoptotic cells, and expression of genes and proteins related to the apoptosis pathway.
