Reviewing nanomaterials in 2024 – types, migration, toxicity

European Union Observatory for Nanomaterials (EUON) study reports nanomaterials in consumer products including food contact materials (FCMs) still on the rise; find “systematic” migration of nanoparticles from FCMs; silver studied the most; no general conclusions on toxicity; review identifies further research gaps and calls to advance regulatory framework to mitigate potential risks associated with nanoparticles in FCMs

What happens to micro- and nanoplastics in the body?

Study proposes a preliminary physiologically-based toxicokinetic (PBTK) model for micro- and nanoplastics (MNPs); polymer type, size, shape, surface chemistry, surface biofilms, and biocorona determine toxicokinetic rates; models for engineered nanoparticles are not appropriate due to heterogeneity of MNPs; uptake via inhalation and effects of absorbed chemicals need more investigation

Studies examine bio-based active packaging and drivers to mitigate pollution

Literature review explores opportunities of bio-based active materials in food packaging applications and the circular economy; demonstrates high research interest in the topic over last 20 years; finds agro-industrial waste as promising, renewable, and environmentally friendly resource for bio-based materials; study finds circular economy to be the focus of perspective articles to mitigate plastic pollution but mismatch with psychosocial research
