Microplastic experts review mammalian in vivo effect studies and develop non-regulatory health-based screening level value for microplastics in drinking water; scientists provide research recommendations to better understand microplastic toxicity, effect levels, and potential health risks to humans and aquatic ecosystems; review discusses nanoplastics’ role in food allergy
Chemical characterization of post-consumer and recycled plastics
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
Stakeholders discuss global plastic treaty
Friends of Europe hosts online debate bringing together stakeholder groups from industry, regulatory agencies, and NGOs; considers how to achieve a circular plastics economy, discusses the necessity of a global plastic treaty, prevention of plastic waste trade and illegal waste dumping, extended producer responsibility schemes (EPRs), need for unified EU plastic waste market; discussions build on report by European Environment Agency, case study by Zero Waste Europe and report by Ellen MacArthur Foundation
Styrene concentrations in German and Italian refrigerated dairy products
Scientists assess styrene levels in polystyrene food packaging, migration into refrigerated dairy products, in 50% ethanol, as well as factors influencing migration; report styrene migration of 5 to 30 µg/kg food at the best before date; find food contact area, temperature and time rather than fat content influence styrene migration
Intelligent packaging: Applications overview
Scientists review basic principles and market applications of intelligent food packaging; discuss the obstacles to a broader market penetration
Plastic recycling: Future scenarios and behavioral influences
Five articles discuss future recycling and/or consumer waste sorting; outline future recycling technologies and recycled plastic applications; identify gaps between recycling technologies and targets of multi-material multilayer plastic packaging; find consumers wrongly dispose bioplastics and that packaging design affects sorting behavior; show single-use bag bans able to increase recycling contamination
Studies review human exposures and effects of micro- and nanoplastics
Three studies investigate micro- and nanoplastics – source, organ deposition, and reproductive effects; detect up to 240,000 plastic particles/L in bottled water with 90% being nanoplastics; find microplastics in human lung, intestine, and kidney tissues; polyethylene particles found to affect placental function in mice
Scientists propose and apply NIAS identification approaches
Review provides guidance to select analytical technique for non-intentionally added substances (NIAS) identification and quantification in food contact materials (FCMs); scientific studies analyze NIAS migrating from FCMs; develop model to predict collision cross-section values to identify NIAS in FCMs; detect polyethylene terephthalate (PET) oligomers in post-mortem blood samples
BPA may be linked to autism spectrum disorder
New study shows BPA is metabolized to lesser extent in children with autism spectrum disorder
FPF Workshop 2020: Values and transparency in science
Kevin Elliott discusses how values can influence scientific judgements or be themselves affected by them; transparency plays an important role in responding to challenges caused by value-laden judgements; contents and venues chosen for transparent communication need to be adjusted according to each stakeholder’s needs
