Scientists investigate plastic particles released from store-bought food packaging as well as human and mice health impacts of exposure; report single-use plastic products release >1012 nano-sized particles during use; find microplastics to suppress lysosomal activity in mouse macrophages; first detection of microplastics within human lung tissue samples; in vitro neurotoxicity study finds microplastics negatively impact human forebrain organoid development
Microplastics in aquatic environment
Microplastics2018 conference addresses sources, fate, effects of microplastics in waste water and aquatic ecosystems
Studies investigate extractable and leachable FCCs, present collision cross section database
Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
FPF Workshop 2020: Hazardous chemicals in FCMs
Stefan Merkel presents recent work of German Institute for Risk Assessment (BfR); Lisa Zimmermann discusses bioassay-based toxicity assessment of conventional plastics, bioplastics, and plant-based materials; Andrew Turner emphasizes presence of toxic brominated flame retardants in recycled plastics, uses of hazardous heavy metals in colored decorations applied to glass articles
Roadmap for EU FCM policy revision
EU Commission’s DG SANTE publishes Inception Impact Assessment as roadmap for revision of EU regulations on food contact materials; outlines eight main “issues” identified during ongoing evaluation, possible policy options to be considered by planned Impact Assessment; commenting period open until January 29, 2021
Studies assess composition and safety of chemicals in recycled HDPE
Scientists analyze volatile compounds in recycled high-density polyethylene (HDPE); detect 53 chemicals in two post-consumer HDPE milk bottles including plastic additives and non-intentionally added substances (NIAS); risk assessment shows samples do not comply with plastic food packaging regulation; report re-granulation process in mechanical recycling to remove most but not all odor and volatile organic compounds
Opinion: Walgreens should pull toxic products
Petition calls upon US drugstore chain to remove toxic chemicals from products, member of Montana Conservation Voters criticizes lacking chemicals policy
Chemical metabolism in young and elderly
Scientists review studies demonstrating differences in drug pharmacokinetics between young and elderly people, recommend use of varying uncertainty factors for acceptable daily exposure calculations due to sensitivity differences
Microplastics detected in human breastmilk and mice fetal thalamus
Two studies assess fetal and infant exposure to plastic particles and impacts on mouse fetuses; detect microplastics in 26 out of 34 human breastmilk samples; report polystyrene particles negatively impact mouse fetuses
New PLA production technology
Dutch scientists develop technology to make production of bioplastic PLA faster and cheaper
