Nanomaterials in FCMs: Open questions on migration and safety

Scientists review migration of nanomaterials from polymer-based FCMs, question suitability of migration testing conditions and diffusion-based models for estimation of nanomaterials migration, point to knowledge gaps regarding actions in human body

Non-target screening of silicone rubber extracts

Scientists perform non-target screening of compounds extracted from infant silicone teats; identify 140 compounds in 12 categories; more than a third of substances need safety evaluation

BfR’s research on nanomaterials

German Institute for Risk Assessment (BfR) summarizes its research on health and environmental safety of nanomaterials and other novel materials; nanoparticle detection optimized in different matrices; animal-free toxicity testing implemented

Health risks of ‘BPA-free’ baby bottles

Scientists evaluate health risks of migrants from ‘BPA-free’ baby bottles made of PP, PA, PES, silicone, Tritan™, stainless steel; silicone bottle, several PP bottles of ‘high concern’; Tritan™ bottle, several more PP bottles of ‘concern’

Migration from aged polycarbonate plastics

Scientists examine influence of ageing on the migration of oligomers and coloring agents from polycarbonate tableware; higher migration of degradation products from older and damaged plastics, colorants from newer products

Chemicals of concern in the circular economy

Scientists find one-fifth of brominated flame retardants’ content in recycling streams is transferred to new products; discuss trade-offs between consumer safety and resource efficiency; European officials maintain toxics can be managed within the circular economy

Analyzing NIAS in paperboard FCMs

Scientists use effect directed analysis to detect and identify aryl hydrocarbon receptor-active substances potentially migrating from pizza box made of recycled paperboard

PAAs in colored paper napkins

Scientists analyze primary aromatic amines in colored paper napkins from Europe; find sum PAA concentrations exceeding 10 µg/L limit, carcinogenic PAAs exceeding 2 µg/L limit; red, orange, yellow, and multi-colored napkins with highest load

Long-term migration from polyester coating

Scientists analyze long-term migration from polyester can coating, find hydrolysis of oligomers after long storage; modification of testing protocols suggested

Food simulant affects nanoparticles

Scientists evaluate changes in size and dissolution of silver nanoparticles in food simulants; nanoparticles dissolve in acidic simulant but remain stable in water and alcoholic food simulant
