Scientists analyze 140 Canadian samples of food packaging and thermal labels; first to demonstrate that bisphenol S (BPS) and alternative chemicals found in food labels migrate through packaging materials into food; study assesses levels of BPS and other bisphenols in 79 canned Turkish foods; detect BPS in six samples in levels up to 0.036 mg/kg food
Global Food Contact Conference 2022: updates from Asia
Smithers conference covers global developments in food contact regulations and materials; speakers on day two review recent and upcoming changes to food packaging regulations in China, Japan, India, and Southeast Asia
UV-328 listed as POP under the Stockholm Convention
11th meeting of the Conference of the Parties to the Stockholm Convention lists UV absorber as Persistent Organic Pollutant (POP); first non-halogenated POP under the Convention; also listing of flame retardant dechlorane plus and pesticide methoxychlor in Annex A
Recent studies on EDCs and cardiovascular health
Emerging evidence and systematic analyses highlight adverse effects of bisphenols and phthalates on cardiovascular health; meta-analysis of US National Health and Nutrition Examination Survey data from 2003-2016 finds significant association of cardiovascular disease with bisphenol A; prenatal exposure particularly detrimental; calls for more mechanistic research, evaluation of cardiovascular safety profiles for substitution chemicals
Studies report on bisphenol exposure and health effects
Review summarizes plastic-associated bisphenol A (BPA) sources, exposure, and human health risks; dietary bisphenol exposure via packaged food consumption in Saudi Arabia is potential human health concern; review discusses bisphenols’ effects on the cardiovascular system and recommends human-relevant studies with bisphenols other than BPA; consensus scoring analysis identifies endocrine-disrupting food contact chemicals potentially interacting with nuclear receptors
PFAS research snapshot Q4 2023: presence, migration, health concerns, and regrettable substitution
Scientists detect two per- and polyfluoroalkyl substances (PFAS) in plastic food storage bags; study assesses PFAS in 119 single-use food packaging and tableware samples from around the world and detectes PFAS in 54%; two reviews raise awareness of PFAS impact on human liver health and safety issues connected with the PFAS substitutes – polyfluoroalkyl phosphate esters (PAPs); scientist calls for more research to assess combined environmental effect of microplastics and PFAS
Micro- and nanoplastics are released from different food contact articles
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
