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
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
BPS and other color developers migrate from food labels into food
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
