Article published in peer-reviewed journal Chemosphere analyzes biodegradable paper straws for presence of per- and polyfluoroalkyl substances (PFAS); tests 38 products, finds PFAS in 36, most frequently detects perfluorobutanoic acid, perfluorooctanoic acid and perfluorohexanoic acid; challenges claim of biodegradability of plant-based straws
JRC proposes improved testing strategies
EU’s Joint Research Centre (JRC) publishes study identifying chemical testing strategies that require fewer tests, reduce need for animal testing; based on data on biocide and plant protection products, could be expanded for use across other product types
Properties of rPET-containing bottles
Scientists examine effects of recycled PET (rPET) on bottles’ properties, propose generic model to calculate acceptable rPET content for different scenarios; bottles from mono-collection systems have less particle contamination, more favorable optical properties, lower accumulation of contaminants, and therefore recommended to allow higher recycled content
PFAS-Tox Database launched
Collaborative group of universities and NGOs publishes PFAS-Tox Database; publicly available resource provides systematic evidence map covering 742 toxicity studies on 29 per- and polyfluoroalkyl substances (PFAS); features dozens of studies on ‘purportedly safer’ PFAS; findings show adverse health impacts studied for wide range of PFAS; experts call for class-based management of all PFAS
Review discusses contaminants in canned food
Scientists summarize literature on chemicals in can-packaged food including metals, plastic-associated chemicals, and furans; report generally low contaminant levels but a lack of non-targeted and suspect screenings; find canning steps, internal and external factors to influence contaminant levels
US EPA announces national recycling strategy
New strategy sets out five objectives including improving markets for recycled commodities, increasing collection, and standardizing measurements; sets nationwide recycling rate target of 50% by 2030; agency to work with stakeholders over coming months on implementation
FDA report on nanotechnology
US Food and Drug Administration reports on advancements in the field of nanotechnology, its role in advancing public health through better regulation; focus on interdisciplinary collaborations and regulatory science research
PFAS alternatives for paper food packaging
Article in Comprehensive Reviews in Food Science and Food Safety discusses alternatives for per- and polyfluoroalkyl substances (PFAS) in paper food packaging; considers lamination with waxes and polymer films, alternative surface sizing and coatings; views finding cost-effective, fully biodegradable, and environmentally friendly alternatives challenging
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
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
