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
Microplastic effects on colon cells, blood lymphocytes, and gut-liver axis
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
Studies investigate extractable and leachable FCCs, present collision cross section database
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
Projects launched to support GHS implementation in Africa
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
Plastic Health Summit 2021: Urgent need for action on plastics
Scientists, activists, industry and policy makers share findings and future needs that address the plastic pollution crisis; recycling plastics is ineffective strategy; concern over possible health effects of micro- and nanoplastics
Nanoparticles in FCMs: Benefits and limitations
Scientists discuss the use of nanoparticles in food packaging materials, focusing on gaps in knowledge on their migration, toxicity, influence on biopolymer degradability
Developing the science-policy panel on chemicals and pollution
National delegations meet in Thailand to discuss the objectives and responsibilities of the new science-policy panel on chemicals, waste, and pollution prevention; in run up to the meeting group of chemical pollution scientists publish article highlighting ten aspects for delegates to consider; non-profit academic organization International Panel on Chemical Pollution hosts webinar on conflicts of interest in chemicals and waste governance
Plastics in a circular economy: research status, environmental leakage, food safety hazards
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
Bamboo in plastic FCMs not authorized in the EU
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
Review discusses contaminants in canned food
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
