Canadian government initiates survey of quaternary ammonium compounds aiming to establish national inventory
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
Ubiquitous exposure to phenolic food contact substances
New study investigates phenolic compounds in pregnant women, finds phenols in more than 90% of specimens, specific phenol exposure may depend on ethnic group
Chemicals in coatings of coffee to go cups
German TV program investigates composition of plastic inner coatings of coffee to go cups; finds samples to contain diisodecyl phthalate and long-chain hydrocarbons
Migration of mineral oils and DIPN from paperboard into dry foods
Swiss and Italian researchers publish new study comparing the effect of different testing and storage conditions on migration behavior of MOSH, MOAH and DIPN from paperboard into non-fatty dry foodstuffs. Observed levels of migration were in the part per million (ppm) range (mg/kg food). Migration levels were highest for egg pasta packaged in paperboard and enclosed in an outer polypropylene bag.
Georgia aligning food contact policy with EU
New EU candidate, Georgia, lowers specific migration limit of lead and cadmium from ceramic food contact articles; brings nation in line with EU Ceramic Articles Directive
Metals in paints on chopsticks
Scientists investigate metals in paints on chopsticks; total concentrations variable with some high values reported, resulting in ‘unacceptable’ health risks for exposure due to incidental paint ingestion or metal migration into food
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
