Five studies on microplastic presence and effects on central nervous system (CNS) and reproductive organs; study finds microplastics of some but not all polymer types enter human CNS, especially after blood-brain barrier impairment; review concludes microplastics induce neurotoxicity; scientists demonstrate presence of microplastics in female reproductive tissue and male para-tumor and tumor prostate samples; associate microplastic presence with sperm dysfunction

Scientists find cyclic polyethylene terephthalate (PET) oligomers migrate into fatty food simulants but not olive oil; levels higher from recycled compared to virgin PET; comprehensive extraction and migration experiments of Tritan™ products find oligomer migration from bottles of no toxicological concern but microwaveable containers were non-suitable for food heating

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

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

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
