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

Study compares toxicity of nanoplastic particles with different sizes and surface charges on human placental cells; demonstrates smaller particles induce higher toxicity; recommend performing nanoplastic risk assessment on reproduction and fetal development

Three studies investigate microplastics in foods; review summarizes particle migration from food packaging into honey and calls for universal analysis methods; research study presents analytical method to detect and identify microplastics in certain foods; survey finds public seems unaware of food packaging as microplastic source and seldomly connects microplastics with human health consequences

European Commission (EC) publishes draft proposal to restrict intentionally-added synthetic polymer microparticles < 5 mm; could ban use of microplastics in cosmetics, cleaning products, pesticides, and sport fields; environmental groups warn of shortcomings

Researchers analyzed microplastics presence in drinking waters; report 7 out of 9 best-selling bottled mineral waters in France contain microplastics; find widespread microplastics contamination of free drinking water refill kiosks across Mexico City

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

Microplastic experts review mammalian in vivo effect studies and develop non-regulatory health-based screening level value for microplastics in drinking water; scientists provide research recommendations to better understand microplastic toxicity, effect levels, and potential health risks to humans and aquatic ecosystems; review discusses nanoplastics’ role in food allergy

Report microplastics occur in lower airways of European citizens with the majority being fibers; evaluate microplastics indoor and outdoor exposure sources; work out established particle domains and paradigms can help predict toxicity of inhaled microplastic particles

Researchers evaluate whether bisphenol A (BPA) and phthalate esters present in microplastics become bioaccessible under simulated physiologically relevant digestion conditions and calculate potential human health risks; conclude that uptake of primary microplastics might pose severe health risks because of the leachability of some endocrine-disrupting additives
