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
US EPA extends PV29 TSCA evaluation comment period
US Environmental Protection Agency (EPA) extends comment period for draft risk evaluation of C.I. Pigment Violet 29 (PV29) under its TSCA regulation; new draft adds previously confidential business data, solubility testing data, workplace air monitoring; concludes 11 of 14 conditions of use for PV29 pose unreasonable risk; toxicity debate ongoing also in Europe; EPA extends comment period for the revised draft until December 19, 2020
Phthalate exposure and health impacts
Four scientific articles report on phthalate exposure sources and impacts; diet partly explains urinary phthalate levels in adolescents and children surveyed in the US and New Zealand; review of reviews summarizes human health impacts; finds studies on women “generally underrepresented”; study indicates three phthalates affect human oral health
UN publishes Plastics Treaty zero draft
The «zero draft» is a starting point for discussion and amendments ahead of November’s Plastics Treaty negotiation in Kenya; each proposed treaty element includes options of varying ambition; Part II focuses on elements of plastics’ life cycle, including chemicals and polymers of concern; Option 1 imposes strict limitations, Option 2 mandates minimal usage, Option 3 leaves it to national action plans; Annex A provides potential criteria for determining chemicals and polymers of concern, along with options for development and usage within the Treaty
Studies present new generic and specific modeling approaches for FCCs migration
Scientists develop nonlinear model for predicting food contact chemical (FCC) migration and apply it to FCCs of high toxicological concern; emphasize usefulness of their model to speed up migration assessment of FCCs; different group of scientists proposes an innovative modeling approach to assess release of a specific additives and elements from plastic food packaging and steel processing tools
Canada intends to approach PFAS as single class
Canadian government announces intention to consider per- and polyfluoroalkyl substances (PFAS) as single class; will continue to support PFAS related research, collect information on how to implement approach, review implementation of other jurisdictions; plans to publish overview report in 2023; approach open for stakeholder feedback about challenges and opportunities
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
EFSA stakeholder workshop on small particles and nanoparticles in food
European Food Safety Authority (EFSA) presentations provide guidance on small particles in food and feed applications (i) evaluating the potential presence of particles in ‘conventional’ materials and (ii) how to perform nano-specific risk assessment; stakeholders share experience and discuss practices to implement guidance cost-effectively
Research defines PFAS planetary boundary and calculates human health costs
Scientists suggest per- and polyfluoroalkyl substances (PFAS) in environmental media represent a new planetary boundary that has been exceeded; calculate that regulatory action on PFAS use and remediation may provide substantial economic benefits through reduction of health-related costs
Study links phthalate exposure and thyroid function in humans
Scientific study investigates effect of plasticizer exposure during pregnancy on thyroid function; outcomes suggest several phthalate metabolites disrupt thyroid hormone levels; finds association of phthalate-alternative DINCH with thyroxine levels
