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
Synergistic interaction in real-life mixtures might not be so rare, scientist finds
“How frequent is rare?” researcher asks, emphasizes that based on current knowledge it is “premature” to neglect chemical synergism in real-life mixtures due to being “rare” and limit focus to additive behavior of chemicals; calls for further research and considering synergism in debates on mixtures risk assessment
What happens to micro- and nanoplastics in the body?
Study proposes a preliminary physiologically-based toxicokinetic (PBTK) model for micro- and nanoplastics (MNPs); polymer type, size, shape, surface chemistry, surface biofilms, and biocorona determine toxicokinetic rates; models for engineered nanoparticles are not appropriate due to heterogeneity of MNPs; uptake via inhalation and effects of absorbed chemicals need more investigation
State of the science and regulation – microplastics and nanoplastics
California State Policy Evidence Consortium and DG Environment publish reports on the abundance, health effects and (potential) regulations on microplastics and nanoplastics, respectively; first finds most regulations come from California or EU and concern banning microbeads or mandating more research; second argues against a lower size cutoff of nanoplastics since the smaller the plastic particles, the more likely they can cross biological membranes
Updated risk assessment highlights the need for stricter regulation on MOH in food
European Food Safety Authority (EFSA) updates risk assessment on mineral oil hydrocarbons (MOH) in food; highest MOH levels found in vegetable oils; notes that data gaps exist, especially in mineral oil aromatic hydrocarbons (MOAH) impact on toddlers; “extremely likely” that dietary exposure to MOAH is a concern for toddlers; EFSA recommendations aim to guide EU policy on allowable MOH levels in food
Stakeholders prepare for the second Plastics Treaty negotiation
United Nations Environment Program (UNEP), industry organizations, scientific research groups, and civil society organizations publish flurry of reports and policy briefs in preparation for second meeting of the Intergovernmental Negotiating Committee on Plastic Pollution (INC-2); meeting takes place in Paris, France May 29 – June 2, 2023
Ban on BPA in European food contact materials moves forward another step
EU expert committee passes ban of bisphenol A in food contact materials; ban will likely be enacted by the end of 2024 with a transition period before coming into force
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
BFFP: 13 key investments to combat plastic pollution
Break Free From Plastic (BFFP) recommends 13 key investments for US federal action; includes funding for multi re-use facility infrastructure, Environmental Protection Agency , research, government, and educational institutions; discourages further investments in chemical recycling, waste-to-energy/fuel technologies, carbon sequestration, downcycling, production, distribution and export of plastics
