Oligomers – presence in FCMs and food, toxicity, challenges
Review summarizes analysis and presence of oligomers in food contact materials (FCMs) made of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polystyrene (PS) including challenges; study suggests ionic strength may influence migration of polyamide (PA) oligomers from PA FCMs

Beyond BPA – Many bisphenols migrate from food packaging
Four studies investigate bisphenol (BP) migration from food packaging and human health effects; demonstrate wide presence of 11 bisphenols in polystyrene take-out food containers from China, Canada, and Poland; report material quality influences BPA migration from polycarbonate cups; indicate higher BPA migration from lined cans than plastic packaging into meat based on probabilistic models; find bisphenols A, F, and S induce genotoxic effects and changes in human endogenous retroviruses (HERVs) expression using human blood cells

Microplastics in placentas: occurrence, sources, and effects
Three studies on microplastics and the human placenta; demonstrate particle presence in several intracellular compartments of placentas for the first time; assume breastfeeding and plastic toy usage as microplastic exposure sources to lactating infants; associate placental plastics with reduced fetal growth

Microplastic exposure through drinking cups and human health impacts
Study finds up to 6000 particles/L to be released from disposable drinking cups; scientists estimate humans ingest 37,613–89,294 microplastics through plastic cups use per year; study suggests consumption from plastic containers changes human gut and oral microbiota composition; review concludes that uptake of microplastics carrying pathogens may impact human health

Microplastics detected in human breastmilk and mice fetal thalamus
Two studies assess fetal and infant exposure to plastic particles and impacts on mouse fetuses; detect microplastics in 26 out of 34 human breastmilk samples; report polystyrene particles negatively impact mouse fetuses

ToMEx – An open access tool to explore microplastic toxicity
Microplastic experts publish Toxicity of Microplastics Explorer (ToMEx), a living database to quickly upload, assess, analyze, and visualize, microplastic toxicity data; aims to inform microplastic research and regulatory decisions on plastic pollution

Pre-consumer and recycled plastic pellets contain hazardous substances
International Pollution Elimination Network and partners publish two studies investigating toxic substances in plastic pellets; virgin plastic pellets recovered from beaches on six continents all contain polychlorinated biphenyls (PCBs) and endocrine-disrupting UV stabilizers; over half of the samples of recycled high-density polyethylene (HDPE) pellets contain at least 11 out of 18 flame retardants and UV stabilizers assessed
