Introduction
Epidemiology
- major sources of microplastics in drinking water include:
- surface runoff, industrial waste, & sewer overflows
- microplastic counts in drinking water range from 0-10,000 particles/liter
- polyethylene terephthalate & polypropylene most commonly detected polymers
Physiology
- humans are unlikely to absorb microplastics > 150 uM
- nM microplastics might be absorbed; effects are unknown
Adverse effects
- no evidence that microplastics in drinking water supply pose a risk to human health at existing levels, but data is lacking[1]
- patients with carotid artery plaque in which containing microplastics & nanoplastics are at increased risk of myocardial infarction, stroke, or all-cause mortality[2]
