Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers
New research on chemical migration from plastic, paper, can coating, and reusables
Recent reports investigate whitening agents’ migration from disposable plastic containers; characterize 153 chemicals migrating from paper packaging and show estimated dietary exposure for children to per- and polyfluorinated alkyl substances (PFAS) exceed safety threshold; detect brominated flame retardants in repeat-use food contact articles; review metal can coating literature concerning coatings types, chemical migrants, detection methods, dietary exposure, and regulatory
Studies investigate circular economy barriers, consumer perceptions
Recent set of articles in peer-reviewed scientific journals review current barriers in flexible plastics to achieving circular economy, recommends regulatory policies be tailored to individual steps in supply chain; consumers easily confused by plastic waste management system, recycling processes, biodegradability claims; researchers instead propose food system shift towards decentralization, shorter supply chains
Measuring plastic particles released from food packaging and in human lungs
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
BPA still in food cans
Extensive analysis in the U.S. and Canada finds most food cans still coated with BPA-based epoxy; BPA-free alternatives may be questionable
Scientists evaluate inhaled microplastics
Report microplastics occur in lower airways of European citizens with the majority being fibers; evaluate microplastics indoor and outdoor exposure sources; work out established particle domains and paradigms can help predict toxicity of inhaled microplastic particles
Monomers migrate from plastics, some are EDCs
In a comprehensive review, researchers from the University of South Africa discuss the monomer migration from plastic food packaging, focusing on known endocrine-disrupting chemicals (EDCs); migration process, potential health impacts discussed
Studies report on oligomer migration from food packaging
Scientists perform migration experiments for oligomer analysis; one study detects eight chemicals including six non-intentionally added oligomers to migrate from multilayer biodegradable teacups; second study reports on oligomer migration from polycarbonate tableware as ‘hidden source’ of bisphenol A (BPA)
A vision for safer food contact materials: Public health concerns as drivers for improved testing
Scientists investigate chemicals in plant-based materials
Review summarizes chemicals present in and migrating from food contact articles made with wood, bamboo, and other plant-based materials; researchers identify and quantify 25 non-volatile compounds from bamboo, palm leaf, wood and wheat pulp dishes; tentatively identify 115 non-volatile chemicals in extracts from six plant fiber/plastic composites; detect phthalates in Brazilian dry foods in cellulose-based packaging
