Microplastics and human health—an urgent problem
Summary
This short commentary draws attention to the ubiquity of microplastic contamination in tap water globally — with studies finding plastics in over 80% of samples worldwide — and urges the medical community to treat microplastics as an urgent public health concern. Sources include synthetic clothing fibers, tire dust, road paint, and the breakdown of larger plastic items.
Microplastics come from many sources: synthetic clothing fibres, dust from tyres, road paints, and the breakdown of larger items. Orb Media's recent investigation has brought the issue of microplastics in the environment into sharp focus. The analysis of tap water samples from around the world found that a high proportion of drinking water is contaminated with microscopic fragments of plastic (83% of samples collected worldwide, but up to 94% in the USA). Microplastic contamination seems more widespread than we perhaps knew, and they are regularly being ingested by people worldwide.
