New research has uncovered a previously overlooked pathway for human exposure to flame retardants, shedding light on potential health risks associated with these chemicals. While flame retardants are credited with saving lives by thwarting fires, they may also pose a threat to human health, according to a study conducted by researchers from Brunel University London and the University of Birmingham in the UK.
Key Points
•Flame retardants, particularly polybrominated diphenyl ethers (PBDEs), have been linked to serious health risks including hormone disruption and cancer.
•The study suggests that skin absorption of PBDEs can occur when the skin comes into contact with microplastics containing these chemicals.
•Using a 3D-printed model of human skin, researchers demonstrated that PBDEs can enter the bloodstream within 24 hours of skin exposure, with sweatier skin absorbing the compounds more efficiently.
•This mode of exposure adds to existing concerns about flame retardants, which are commonly found in consumer products like foam padding and wire insulation.
•While some flame retardants have been banned in recent years, others remain in use, contributing to ongoing exposure risks.
•The study underscores the need for further research to understand the health implications of exposure to microplastics and associated chemicals.
•Lead author Ovokeroye Abafe emphasizes the importance of regulatory action to address these risks and protect public health.
Implications and Future Research
•The findings highlight the potential dangers of skin absorption of flame retardants, adding to existing concerns about their health effects.
•Urgent action is needed to address the continued prevalence of flame retardants and their associated risks.
•Further research is necessary to fully understand the implications of skin absorption of flame retardants and to explore the broader impact of microplastics on human health.
As scientists continue to unravel the complexities of chemical exposure and its effects on human health, regulatory measures and public awareness efforts are essential to mitigate risks and safeguard public well-being.
