Effect-directed analysis study identifies hazardous substances in FCMs

Researchers analyze coffee‑to‑go cups and takeout containers for their in vitro toxicity and the identities of the chemicals responsible for the observed effects; detect cytotoxic, genotoxic, and endocrine‑disrupting effects and prioritize hazardous chemicals

Widely used plastic chemicals activate retinoid-X-receptor, scientists find

Study combines in silico, in vitro, and in vivo methods to identify food contact chemicals interfering with retinoid-X-receptor (RXR), potentially leading to adverse biological outcomes by endocrine disruption; predicts 104 RXR-interacting chemicals, dominated by 58 butylphenols; three of six tested tert-butylphenols potentiate thyroid hormone signaling at nanomolar levels; identifies structural features that enhance RXR binding

Microplastics found along the maternal-fetal axis, impacting placenta

Scientists detect microplastics in maternal blood, fetal appendages, and umbilical vein blood; find no association between particle levels measured in different tissues; polystyrene microplastics induce time-dependent cytotoxicity, oxidative stress, and metabolic alterations in placental explants; reviews discuss microplastic association with different diseases

Researchers argue US regulatory frameworks are outdated, lag behind advancements in toxicology

In an opinion piece in Frontiers in Toxicology experts argue that multiple assumptions made by EPA and FDA are outdated; wrongly assume chemicals are quickly eliminated from the body, testing chemicals individually reflects real-world exposure scenarios; authors call for integrating modern scientific principles like mixture toxicology and endocrinology

Recent studies show that MNPs can negatively impact reproductive health

Studies confirm micro- and nanoplastics (MNPs) in human endometrial tissue, amniotic fluid, placentas, and feces of pregnant people; MNP presence in the endometrium is linked with recurrent miscarriages in humans, apoptosis in organoids, and reduced fertility in mice; higher MNPs exposure from seafood and bottled water consumption

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

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

Study detects DNA-reactive, mutagenic substances in recycled PE, PP, and PS

119 plastic samples including polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET) tested for mutagenicity; no DNA-reactive, mutagenic substances in PET but in 51 of the other samples, making them unsafe, especially for food contact applications; recycling process identified as source; dataset of over 600 organic chemicals in recycled high-density PE pellets published
