European member states agree to recognize perfluorobutane sulfonic acid (PFBS) as a substance of very high concern (SVHC); cite equivalent concern to carcinogenic, mutagenic, reprotoxic substances, high mobility in environment
New form of PLA seen as beneficial for application in hot food packaging
Researchers develop a more thermally resistant form of polylactic acid (PLA) plastic; provides clear, tough, and heat resistant material with the potential to expand PLA market application and reduce price
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
Cost of EU chemicals regulation
European Commission publishes study assessing the cost of regulation on EU’s chemical industry; CHEM Trust and Cefic release commentaries
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
UV-328 qualifies for screening as POP
Persistent Organic Pollutants Review Committee (POPRC) meeting finds antioxidant UV-328 (TINUVIN-328) fulfills all four criteria for screening as Persistent Organic Pollutant (POP) under the Stockholm Convention; next step is the preparation of a draft risk profile for the widely used plastic additive
Dietary intake of BPA in the US
New study estimates BPA intake of US adults via diet, canned vegetables are a major contributor to exposure
