Ensia article informs about plastic water piping material PEX; discusses what is known and unknown about the material’s composition and what leaches out into water
Microplastics in aquatic environment
Microplastics2018 conference addresses sources, fate, effects of microplastics in waste water and aquatic ecosystems
Opinion: Plastic packaging should be simplified
Cradle to Cradle scientist Michael Braungart calls for fewer and simplified polymers to create material cycles rather than waste
Oligomer migration from PET and Tritan™
Scientists find cyclic polyethylene terephthalate (PET) oligomers migrate into fatty food simulants but not olive oil; levels higher from recycled compared to virgin PET; comprehensive extraction and migration experiments of Tritan™ products find oligomer migration from bottles of no toxicological concern but microwaveable containers were non-suitable for food heating
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
US Senate passes bills to increase recycling accessibility, data
United States Senate unanimously passes the Recycling Infrastructure and Accessibility Act, Recycling and Composting Accountability Act; both receive wide support from industry and environmental groups; must pass House of Representatives to become national policy
FPF comments on EU’s broad PFAS restriction proposal
The Food Packaging Forum (FPF) provides the European Chemicals Agency (ECHA) scientific information on per- and polyfluoroalkyl substances (PFAS) in food contact materials (FCMs) ahead of Risk Assessment Committee meeting; emphasizes concerns about PFAS’ persistence as a multiplier of toxicity; provides data on PFAS detected in and migrating from FCMs
Aggregate exposure assessment for BPA
Scientists discuss aggregate exposure assessment for bisphenol A; source-to-dose (forward) and biomonitoring-based (backward) calculation resulted in similar estimates; 90% of exposure comes from diet and the remaining 10% mainly from dermal exposure
Non-target screening of silicone rubber extracts
Scientists perform non-target screening of compounds extracted from infant silicone teats; identify 140 compounds in 12 categories; more than a third of substances need safety evaluation
Study reveals knowledge gaps on PET oligomers migrating from FCMs
Scientists investigate available research on hazard and exposure of 34 oligomers in PET for food contact; 74% of them found to migrate; only 38% have been tested for their safety using computer models, while only one was tested for safety in organisms; authors call for further research and better risk assessment
