Scientists perform target and non-target screening of recycled plastics and provide recommendations on methods; detect >280 organic chemicals and metals in 21 plastic flakes and pellets used in recycling; analyze several recycled polymers and find polyethylene terephthalate (PET) the only one currently complying with European circular economy requirements; compare analytical methods to assess the chemical composition of recyclates giving their strenghts and limitations
EFSA study: Bioaccumulation and toxicity of mineral oils
New EFSA scientific study tests different mixtures of mineral oil saturated hydrocarbons (MOSH), relevant to human diet, in rats; bioaccumulation at low dose MOSH exposure in humans possibly underestimated; MOSH appear persistent in adipose tissue
US states continue to develop local PFAS regulations
Maryland bans intentionally added PFAS in paper and board packaging, disposable plastic gloves by January 2024; Washington State accelerates PFAS Chemical Action Plan, Department of Ecology reported to be hiring more staff to undertake the accelerated timeline; Washingtonians say food related products should be main concern of state’s Safer Products for Washington Program; Vermont considers banning bisphenols in food packaging
Standardizing Benchmark Dose (BMD) calculations
New study assesses reliability of standardized Benchmark Dose calculations, more dose groups and lower number of animals make for better BMD model
EFSA opinion on PFOA and PFOS in food
EFSA scientific opinion suggests revision of tolerable intake values for two perfluoroalkyl substances
Plastic recycling: company commitments and chemical safety challenges
Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers
2nd Safe and Sustainable by Design Stakeholder Workshop
Parabens increase BPA exposure
Parabens inhibit several biotransformation enzymes involved in steroid hormone metabolism and chemical detoxification; study in mice shows that co-exposure with butyl paraben results in elevated internal levels of estradiol and BPA
EFSA publishes mixtures methodology
European Food Safety Authority launches guidance on assessment of ‘combined effects’ of chemical mixtures in food and feed
Beyond BPA – Many bisphenols migrate from food packaging
Four studies investigate bisphenol (BP) migration from food packaging and human health effects; demonstrate wide presence of 11 bisphenols in polystyrene take-out food containers from China, Canada, and Poland; report material quality influences BPA migration from polycarbonate cups; indicate higher BPA migration from lined cans than plastic packaging into meat based on probabilistic models; find bisphenols A, F, and S induce genotoxic effects and changes in human endogenous retroviruses (HERVs) expression using human blood cells
