Occurrence of PBDEs in car and airplane dust in Poland – exposure assessment and health risk characterization for selected age ranges
AI summary Read the abstract
Researchers measured polybrominated diphenyl ether (PBDE) flame retardant concentrations in dust from cars and aircraft in Poland, finding that levels across all measured congeners did not pose a health risk to any of the age groups assessed through dust ingestion exposure.
The levels of tested PBDE congeners measured both in car and aircraft dust did not indicate health risk for these selected populations resulting from ingestion of dust.

Screening of halogenated flame retardants and microplastics in indoor air from various microenvironments in Barcelona, Spain
AI summary Read the abstract
Researchers tested indoor air and dust in Barcelona homes, workplaces, and cars for flame retardant chemicals and microplastics, finding that dust (not air) contains the highest levels of these substances, with breathing them in being the biggest exposure route. The good news: measured exposure levels were below thresholds considered risky for health. However, since the study didn't account for exposure through food or certain airborne chemical forms, actual total exposure could be higher—meaning continued monitoring is important to catch potential health risks before they become a real problem.
Determination of bisphenol A in size fractions of indoor dust from several microenvironments
AI summary Read the abstract
This study measured bisphenol A (BPA) — a harmful chemical found in many plastics — across different size fractions of indoor dust collected from homes, offices, and shops. BPA concentrations varied by dust particle size, suggesting fine indoor dust is a significant pathway for human BPA exposure.
Microplastics and Associated Organic Pollutants in Indoor Environments
AI summary Read the abstract
This review pulls together what scientists currently know about microplastics floating in our indoor air and settling into household dust — and it turns out we're breathing and swallowing more of these tiny plastic particles than expected, especially in cities and near waste facilities. These particles often carry harmful chemicals like phthalates and flame retardants, and kids are exposed to higher doses than adults. The takeaway: our homes and indoor spaces are a significant, underappreciated source of plastic exposure, and more research is needed to figure out how to reduce it.
Endocrine disrupting chemicals in indoor dust: A review of temporal and spatial trends, and human exposure
AI summary Read the abstract
This review examines endocrine-disrupting chemicals found in indoor house dust, including phthalates, flame retardants, bisphenols, and PFAS, many of which come from plastic products. Even though some of these chemicals have been banned, they are still widely detected in dust, while their replacement chemicals are showing up at increasing levels. The findings are relevant to microplastic concerns because many of these hormone-disrupting chemicals are the same additives found in plastics that leach out as microplastics break down.
Bisphenol A and its analogues in outdoor and indoor air: Properties, sources and global levels
AI summary Read the abstract
This review covers the presence of bisphenol A (BPA), a hormone-disrupting chemical used in plastic manufacturing, in indoor and outdoor air worldwide. BPA exposure through air and dust is a concern because it can interfere with hormones even at low levels, potentially affecting fertility, development, and metabolism. The review is relevant to microplastics because BPA is a common plastic additive that can leach from microplastic particles, adding to human exposure through multiple routes.
