JRC Symposium compares microplastic analysis methods

Excerpt: 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as a challenge for scientific community and industry due to lack of hazard data, a missing harmonized methodology, and outdated regulatory guidelines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

Global Food Contact Conference: NIAS evaluation in recycled packaging

2021 Smithers Pira conference covers global developments in food contact regulations and materials including a session on the risk assessment of non-intentionally added substances (NIAS); Marco Zhong outlines efforts China is taking to assess NIAS in recycled and biodegradable materials for safe food contact application; Marinella Vitulli focuses on applied testing schemes for NIAS identification, stresses that the right analytical approach is key

In vitro toxicity of bioplastics and plant-based materials

Scientists investigate in vitro toxicity of extracts from bioplastics and plant-based food contact articles; find strongest toxicity induced by cellulose- and starch-based products; emphasize similar toxicity profiles among bio-based, biodegradable, and conventional plastics

Salinity of fatty food could influence migration

JRC scientists investigate influence of salinity level of food simulants on migration; argue that not only fatty content but also salinity of food needs to be considered when choosing migration testing conditions for polar migrants
