Study finds up to 6000 particles/L to be released from disposable drinking cups; scientists estimate humans ingest 37,613–89,294 microplastics through plastic cups use per year; study suggests consumption from plastic containers changes human gut and oral microbiota composition; review concludes that uptake of microplastics carrying pathogens may impact human health
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
Second study finds microplastics in human placenta
Clinical study investigates 10 microplastic types in human placenta and meconium; detects polyethylene, polypropylene, polystyrene, and polyurethane in the samples; highlights that evaluation and control of potential contamination is crucial
Studies detect microplastics in bottled and outdoor drinking water
Researchers analyzed microplastics presence in drinking waters; report 7 out of 9 best-selling bottled mineral waters in France contain microplastics; find widespread microplastics contamination of free drinking water refill kiosks across Mexico City
Biomonitoring provides insights into nonylphenol exposure in Germany
Retrospective analyses of urinary nonylphenol (NP) levels in German students over past 30 years demonstrate omnipresence of NP exposure; scientists recommend using NP metabolites as biomarkers for NP exposure assessment; analysis points to foodstuff as major exposure source
Packaging sustainability during the pandemic
Consultancy McKinsey & Company publishes paper on consumers’ views towards sustainability in packaging, as influenced by COVID 19 pandemic; urges more focus on proactive communication with consumers and supply chain partners, holistic approach to sustainability and hygiene requirements
EFSA CEP Panel updates from October 2022 to February 2023
Minutes available from recent meetings of the working groups on food contact materials (FCMs), bisphenol A (BPA), and recycling plastics, within the European Food Safety Authority’s (EFSA’s) Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel); no further meeting of the BPA working group planned; specific migration limit (SML) for styrene in FCMs upcoming
European Commission introduces EDC subcategories and new hazard classes in CLP revision
Commission amends regulation on classification, labeling, and packaging (CLP) of chemicals and mixtures; endocrine disrupting chemicals now categorized into known or presumed and suspected endocrine disruptors; introduces four hazard classes from REACH
PFAS measuring protocols likely underestimate total concentrations
Study of PFAS concentrations in consumer products finds that US Environmental Protection Agency protocol likely does not “adequately capture PFAS embodied in consumer products”; also finds “large fraction” of surface and groundwaters exceed regulatory concentrations; “future PFAS environmental burden is likely underestimated”
Majority of plastic food contact articles likely endocrine and metabolism disrupting
Two studies investigating chemicals from retail plastic food contact articles find considerable variability in complexity, with subsequent effects on cell-based tests of hormone disruption; many more chemicals measured from PVC and polyurethane than other polymers though the chemical mixtures from majority of the plastic samples are hormone disrupting; further evidence of PVC and PUR can interfere with GPCR-based cell communication
