New report by the National Academies of Sciences presents strategy to evaluate low-dose effects of endocrine active substances, provides systematic reviews for phthalates and PBDEs
Review summarizes current picture of 'human-centric' micro- and nanoplastics research
Scientists review and briefly summarize available scientific literature on each step of microplastic exposure from source to effect in humans; includes sections on sources of microplastics, exposure routes, levels, deposition in the body, and confirmed health effects; highlight current shortcomings
Microplastic exposure through drinking cups and human health impacts
Study finds up to 6000 particles/L to be released from disposable drinking cups; scientists estimate humans ingest 37,613β89,294 microplastics through plastic cups use per year; study suggests consumption from plastic containers changes human gut and oral microbiota composition; review concludes that uptake of microplastics carrying pathogens may impact human health
BPA absorption in the mouth
Scientists compare internal levels and metabolism of BPA after gavage or diet administration; demonstrate significant buccal absorption of BPA from solid foods
Industry group challenges UN cancer classifications
American Chemistry Council launches campaign to reform WHO cancer agencyβs evaluation of carcinogenic risks to humans, criticizes hazard-based substance assessment
Microplastic impacts on child health: knowns and unknowns
Scientific commentary discusses pregnancy- and child-relevant exposure to and impacts of nano- and microplastics: finds 37 studies mostly on plastic particles in food and placental transfer, identifies major knowledge gaps, and advocates policymakers and industry to implement precautionary approaches; Nature Reviews Materials article proposes microplastic risk assessment framework
Human exposure to BPA systematically underestimated
New study shows that different measurement methods lead to large discrepancies in BPA human body burdens; human population exposed to higher levels of BPA than estimated using standard method; human health risk of BPA likely underestimated
Microplastics may affect the human microbiome
Scientists explore potential impacts of microplastics on human intestine ecology; microplastics may drive unhealthy changes in the gut microbiome; authors highlight importance of assessing human microplastics exposure and hazards for the gut
