Interactive Effects of BDE-153 and itsMetabolite 2,4-DBP on Biochemical Statusin Crucian Carp (Carassius auratus)
AI summary Read the abstract
This study examined how polybrominated diphenyl ethers (PBDEs) — flame retardants found in many plastics — and their metabolites affect biochemical markers in organisms. The findings suggest that even metabolized breakdown products of plastic-associated flame retardants can disrupt normal biological functions.
Polybrominated diphenyl ethers (PBDEs) are organic chemicals that have been commonly applied as flame retardants in plastics, textiles, electronic castings, and items containing polyurethane foam that were produced as three major commercial formulations: penta-BDE, octa-BDE, and deca-BDE Once used, PBDEs are released into natural aquatic systems via different routes and were found in both abiotic and biotic environmental samples over the last decade Moreover, PBDEs as persistent organic pollutants are well known for their persistence, bioaccumulation, long-range transport potential, and toxicity

Further negative effect of fibrous microplastics to the bioaccumulation and toxicity of decabromodiphenyl ethane on zebrafish
AI summary Read the abstract
Researchers investigated how fibrous microplastics from PET plastic interact with a common flame retardant chemical called DBDPE in zebrafish over 28 days. They found that microplastics significantly increased the amount of the flame retardant that accumulated in fish tissue and slowed its elimination from the body. The study suggests that microplastics may act as carriers for other toxic chemicals, amplifying their harmful effects on aquatic organisms.
Metabolic Consequences of Developmental Exposure to Polystyrene Nanoplastics, the Flame Retardant BDE-47 and Their Combination in Zebrafish
AI summary Read the abstract
Researchers examined how developmental exposure to polystyrene nanoplastics and the flame retardant BDE-47, alone and combined, affects zebrafish metabolism, finding that co-exposure produced distinct metabolic disruptions beyond those caused by either contaminant individually.
Ecotoxicological responses of juvenile Sparus aurata to BDE-99 and BPA exposure: A multi-biomarker approach integrating immune, endocrine and oxidative endpoints
AI summary Read the abstract
Researchers chronically exposed juvenile sea bream (Sparus aurata) to the flame retardant BDE-99 and the plasticizer BPA, finding that combined exposure produced the most severe disruption of endocrine and immune biomarkers, highlighting that mixture effects of environmental contaminants pose greater risks to marine fish than individual exposures.
New brominated flame retardant decabromodiphenyl ethane (DBDPE) in water sediments: A review of contamination characteristics, exposure pathways, ecotoxicological effects and health risks
AI summary Read the abstract
This review examines DBDPE, a newer flame retardant chemical that is increasingly found in water sediments worldwide as it replaces older banned compounds. Evidence indicates that DBDPE concentrations are rising rapidly and the chemical poses ecological and health risks through bioaccumulation in aquatic food chains. The findings are relevant to microplastic research because flame retardants are common plastic additives that leach into the environment.
Influence of polystyrene microplastics on bioconcentration and metabolism of 2-ethylhexyl diphenyl phosphate in common carp (Cyprinus carpio)
AI summary Read the abstract
Tiny plastic bits (microplastics) can stick to a common flame-retardant chemical found in furniture and electronics, changing how it builds up and breaks down inside fish. In this study, fish exposed to both microplastics and the chemical together took longer to clear it from their bodies, meaning the combo may linger in their system longer than the chemical alone. Since fish are a major food source, this suggests microplastic pollution could indirectly affect how long other chemicals persist in the seafood we eat, highlighting a health risk that needs more research.
