HuffPost article addresses draft CLARITY-BPA report, various approaches to toxicity testing by regulatory and academic scientists, impact on future chemical risk assessments
Fluorotelomers in bio-based paper FCMs
Fluorotelomer alcohols measured in paper FCMs; high levels found in ‘eco-friendly’ bio-based paper packaging; metabolic transformation to hazardous perfluorinated acids possible
Urinary bisphenol A levels may influence onset of menarche
Study finds moderate concentrations of urinary BPA associated with overall delayed menarche in adolescent girls
New method to evaluate effects of electron beam treatment on chemical migration in PP films
New two-dimensional gas chromatography method assesses effects of electron beam treatment of polypropylene films on composition of chemical migration extracts.

Genotoxic chemicals in coatings
Scientists compile inventory of compounds potentially used in coatings; 1,976 substances have no (recent) toxicological evaluation; subset analyzed by in silico tools and literature search, 10 compounds designated as ‘high concern’
What happens to micro- and nanoplastics in the body?
Study proposes a preliminary physiologically-based toxicokinetic (PBTK) model for micro- and nanoplastics (MNPs); polymer type, size, shape, surface chemistry, surface biofilms, and biocorona determine toxicokinetic rates; models for engineered nanoparticles are not appropriate due to heterogeneity of MNPs; uptake via inhalation and effects of absorbed chemicals need more investigation
New FPF study and database: Food contact chemicals in humans
New research from the Food Packaging Forum looks at food contact chemicals (FCCs) that have been detected in humans; compares known FCCs with human biomonitoring programs, metabolome/exposome databases and the scientific literature; 3,601 FCCs have evidence of presence in humans, including chemicals with hazardous properties; comes with interactive dashboard to browse all data
State of the science and regulation – microplastics and nanoplastics
California State Policy Evidence Consortium and DG Environment publish reports on the abundance, health effects and (potential) regulations on microplastics and nanoplastics, respectively; first finds most regulations come from California or EU and concern banning microbeads or mandating more research; second argues against a lower size cutoff of nanoplastics since the smaller the plastic particles, the more likely they can cross biological membranes
Toward a guidance to assess safety of food packaging coatings
Interlaboratory study evaluates protocol for consistent safety assessment of coated metal packaging materials; guidance comprises sample preparation, chemical and biological analysis; finds technical differences affect outcome; emphasizes need for aligned protocol to avoid inconsistencies
