Summary: Assessing human exposure to flame retardants via dust ingestion is uncertain due to factors such as spatial and temporal variability, differences in dust particle size fraction, and dust sampling methods. Concentrations of flame retardants in elevated surface dust tend to exceed those in floor dust, potentially resulting in underestimation of exposure for adults and overestimation for toddlers. Significant differences in flame retardant concentrations across different particle size fractions of dust suggest potential implications for exposure assessment.

Summary: Brominated flame-retardants (BFRs) are environmental endocrine disruptors that potentially affect the endocrine system and cause dysfunction and disease. Widespread BFR exposure may cause multisystem toxicity, including cardiovascular toxicity in some individuals. BFRs not only increase heart rate, induce arrhythmia and cardiac hypertrophy, but also cause glycolipid metabolism disorders, vascular endothelial dysfunction, and inflammatory responses, all of which potentially induce pre pathological changes in atherosclerosis.

Summary: Limited information exists regarding the contamination of brominated flame retardants (BFRs) in lake sediments from Vietnam and Southeast Asia. This study analyzed surface sediment samples from urban lakes in Hanoi and found relatively high concentrations of polybrominated diphenyl ethers (PBDEs), with BDE-209 being the predominant congener. Other BFRs were present at lower concentrations. The study also revealed a significant correlation between BDE-209 and decabromodiphenyl ethane (DBDPE), suggesting similar applications and/or environmental fate. Wastewater discharge, riverine inflow, and atmospheric deposition were identified as potential sources of BFRs in lake sediments.

Summary: The study found detectable concentrations of a range of environmental pollutants such as BFRs, NFRs, and PCBs in outdoor air in Lagos, Nigeria. While PBDEs and some NFRs showed correlation with population density, PCB concentrations appeared to be more influenced by factors like leaks from electrical transformers and proximity to industrial activities like textile factories. The tropical climate of Lagos may contribute to the lack of seasonal variation in concentrations of these contaminants.

Summary: This review paper comprehensively discusses the management and research aspects of e-waste in an Asian developing country. The lack of effective management and recycling systems in Vietnam has resulted in localized contamination and human exposure to toxic chemicals. Primitive processing activities have been identified as significant contributors to environmental emissions and human exposure to toxic elements and pollutants. Informal e-waste processing releases pollutants at similar levels as large-scale facilities in developed countries.

Summary: Animal experiments suggest that pesticides may impact gut microbiota and the production of SCFAs and polyamines. This study investigated the relationship between pesticide exposure and fecal SCFAs and polyamines in Japanese adults. The findings indicate that OP exposure is independently associated with lower fecal acetate levels, possibly affecting the health of middle-aged and older adults. Further studies on a wider age range, including children, are needed to fully understand the long-term effects of pesticide exposure on gut health.
