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 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: 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: The study conducted in Tianjin, China, revealed that PBDE concentrations in urban soils have decreased in recent years, primarily originating from local industrial production processes and consumer products. More research is needed to further investigate the changing trend of PBDE pollution and its potential impact on human health.

Summary: This study identifies key genes potentially involved in the impairment of adrenocortical secretory function caused by hydroxylated polybrominated diphenyl ethers (OH-PBDEs). Functional enrichment analysis and protein-protein interaction network construction were performed to explore the underlying mechanisms. The results suggest that OH-PBDEs may disrupt endocrine metabolism, abnormal cell proliferation, DNA damage, and repair. The identified hub genes may play an important role in these dysfunctions.

Summary: This study investigated the size distribution and levels of PBDEs during the dismantling and recycling of waste household appliances in authorized plants in China. The results showed that coarse particles dominated the particulate matters, and PBDEs mainly deposited in the head airways. The estimated daily intake of PBDEs through inhalation and dust ingestion were below the reference doses.

Summary: The study aimed to assess the association between dietary intake of PBDEs and breast cancer risk, and investigate the potential modification of this association by vegetable oil consumption. The results showed a positive linear trend between dietary intake of PBDEs and breast cancer risk, with potential modification by vegetable oil consumption.

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: 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: This study aimed to determine PBDE levels in human milk from 25 mothers in Poland and assess the risk for breastfed infants using EFSA and U.S. EPA methodologies. It was found that the daily intake of PBDEs from breast milk for infants was below the U.S. EPA RfD, indicating no health risk, but potential health concerns were identified regarding exposure to BDE-99 based on EFSA methodologies.

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.
