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)
Study analyzes unknown chemicals in recycled plastic
Scientists develop automated non-target approach to identify and risk assess unknown chemicals in food contact plastics; detect over 300 chemical features and tentatively identify 83 compounds in a recycled polyethylene film used as proof-of-concept
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
JRC Symposium compares microplastic analysis methods
European Commission’s Joint Research Centre (JRC) symposium summarizes current approaches for microplastic monitoring; research institutions present results of 4 inter-laboratory microplastic analysis comparison studies; no ‘one-size-fits-all’ analytical method, presenters emphasize need for harmonization; Commission outlines policy needs
Study finds UV stabilizers with endocrine-disrupting potential in plastics
Research study identifies 8 of 13 benzotriazole UV stabilizers (BUVSs) as endocrine disruptors; finds 8 of 9 tested BUVSs in polyolefin packaging
Bisphenols in thermal paper extracts and drinking bottle migrates
Scientific studies analyze bisphenol content in thermal papers and migrates from reusable drinking bottles; of 14 analyzed bisphenols 4 detected in thermal receipts and 3 in bottles migrates at low concentrations; dishwashing but not handwashing prior to use reduces bisphenol A (BPA) leaching from Tritan
Study characterizes chemicals present within recycled products
Scientific study characterizes chemicals contained in 210 consumer products made of recycled or virgin material regarding identity, functional use, structural class, and origin and prioritizes chemicals; 65% of chemicals with greater concentrations in recycled materials, along with a higher number of flame retardants, biocides, dyes, and fragrances in recycled materials
NIAS migration from plastic wine corks
Scientific study uses non-targeted chemical analysis to provide an overview of chemicals migrating from 8 wine corks made of ethylene-vinyl acetate; identifies 50 compounds, 84% non-intentionally added substances (NIAS); finds one cork not suitable as food contact material
Review investigates challenges of assessing NIAS in plastic FCMs
Literature review summarizes challenges regarding non-intentionally added substances (NIAS) in plastic food contact materials (FCMs); describes 52 studies with their applied methodologies for NIAS extraction and identification, plastic types analyzed, and NIAS detected; highlights NIAS assessment as a challenge for scientific community and industry due to lack of hazard data, a missing harmonized methodology, and outdated regulatory guidelines
Whistleblowers claim EPA is hiding chemical risks
The Intercept reports four career staff members of the US Environmental Protection Agency (EPA) claim that the agency is hiding risks discovered in toxicological assessments of chemicals; plans additional follow-up articles to further investigate the claims
