Microplastics early ’25 science round-up: presence in humans and health impacts

February 14, 2025

Scientists detect more micro- and nanoplastics (MNP) in the human brain than in liver and kidney, higher levels in brains of dementia patients; find MNPs obstruct blood vessels, lead to neurobehavioral abnormalities; MNPs in women’s follicular fluid associated with lower fertilization rates; maternal MNP exposure impairs fertility of female mice offspring; “bioplastic” MNPs induce male reproductive toxicity in mice

Microplastics in blood linked to impaired blood clotting, study finds

January 14, 2025

South Korean study assesses link between microplastics in blood and plastic container use as well as blood coagulation disruptions; finds mostly polystyrene, polypropylene, and polyethylene microplastics in blood; links higher microplastic levels to use of plastic containers, impaired blood clotting and increased inflammation, suggesting potential cardiovascular risks

Microplastics found along the maternal-fetal axis, impacting placenta

December 13, 2024

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
