Researchers report cooking in non-stick Teflon cookware may lead to the release of thousands of micro- and nanoplastics; find 3 to 43 plastic particles prone to be released from Chinese polypropylene takeaway containers; detect around 1,500 microplastics/liter in Iranian bottled water; review points out that micro- and nanoplastic detection methods in food need validation and standardization
Two in vitro studies analyze plastic particle effects using human cells; find polystyrene (PS) particles change metabolism of human colon cells similar to a carcinogen; PS nanoplastics may have cytotoxic and genotoxic potential on human blood lymphocytes; mouse study indicates microplastics increase risk of insulin resistance; researchers calculate particle ingestion from takeaway containers
Scientists develop collisions cross section (CCS) database for leachable and extractable food contact chemicals (FCCs) to help in chemical identification during targeted and untargeted analysis; database covers 1038 CCS values; study tentatively identifies >100 migrants from 24 plastic food packaging articles including 11 that are of potential concern or are priority hazardous substances
Kenya, Ghana, Cote d’Ivoire, Nigeria, and Rwanda implementing Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in national policy; Sierra Leone and Malawi partner with the UN Environment Program (UNEP) to study chemical and waste management within the countries to design long term policies and projects
Recent studies perform semi-systematic review of published circular economy literature focusing on plastics over past 21 years, develop framework for plastics in circular economy; find Dutch food packaging plastic waste polluting oceans, question effectiveness of recycling; summarize chemical and microbial hazards related to circular food production systems
European Commission’s Working Group concludes that bamboo-based additives are not authorized per se for use in plastic food contact materials in the EU; business operators to explicitly demonstrate safety by migration testing; migration of melamine, formaldehyde of high concern; additional concerns about misleading labeling and advertising
Scientists summarize literature on chemicals in can-packaged food including metals, plastic-associated chemicals, and furans; report generally low contaminant levels but a lack of non-targeted and suspect screenings; find canning steps, internal and external factors to influence contaminant levels
2021 Smithers Pira conference covers global developments in food contact regulations and materials including a session on the risk assessment of non-intentionally added substances (NIAS); Marco Zhong outlines efforts China is taking to assess NIAS in recycled and biodegradable materials for safe food contact application; Marinella Vitulli focuses on applied testing schemes for NIAS identification, stresses that the right analytical approach is key
Zero Waste Europe and Eunomia investigate the circularity of single-use container glass in Germany, France, the UK and US; Germany has the highest collection rates for glass and the highest proportion of recycled glass in containers; US is the lowest due to lack of collection facilities and mixed collection of glass with other packaging types; collecting glass separately and by color is the most effective way to increase circularity
New method for the detection of contaminants in in recycled paper and paperboard. Significant levels of BPA, DEHP and nonylphenols found in commercial retail samples of recycled paperboard food contact materials.
