Study finds metabolism- and endocrine-disrupting chemicals present in plastic food packaging can migrate

A recent study explores the diversity of chemicals migrating from food contact articles into food simulants; 73% of extractable chemicals also migrated to food simulants; only 2% could be matched to currently known plastic chemicals; all migrates activated nuclear receptors, may disrupt metabolism or the endocrine system; migrates from PUR, PVC and LDPE contained more chemicals than other tested polymers and were more toxic

Chronic PS nanoplastics exposure found to impact mitochondrial health, impairing cell metabolism

New study examines long-term effects of polystyrene (PS) nanoplastics on mitochondrial health under realistic exposure conditions; repeated exposure to PS nanoplastics impaired mitochondrial function and cell differentiation process, possibly linked to metabolic disorders, such as diabetes and obesity; other recent studies found that PS micro- and nanoplastics negatively affect immune function, pregnancy outcomes, and gut health in various models

Majority of plastic food contact articles likely endocrine and metabolism disrupting

Two studies investigating chemicals from retail plastic food contact articles find considerable variability in complexity, with subsequent effects on cell-based tests of hormone disruption; many more chemicals measured from PVC and polyurethane than other polymers though the chemical mixtures from majority of the plastic samples are hormone disrupting; further evidence of PVC and PUR can interfere with GPCR-based cell communication
