Bottled Water Has More Microplastics Than Tap — But How Much?

A 2024 study measured microplastics in Spain's top-selling bottled water. The dose is tiny, but two to three orders of magnitude higher than tap water.

Can a Laser Spot Microplastics in Water in Real Time?

Lab methods can't test in the field. This sensor concept uses three laser-diode lines to screen microplastics in water—here's how it works, and its limits.

How Reliable Is the Data on Microplastics in Drinking Water?

A WHO-led review scored 50 studies on microplastics in water. Only four passed every quality check — which is why exposure claims deserve caution.

How Much Microplastic Is in Bottled Water? What One Study Found

A 2018 study tested 259 bottles across 11 brands and nine countries. 93% showed microplastic contamination — and the packaging itself appears to be a source.

Nanoplastics in Bottled Water: What One Liter Actually Holds

A 2024 PNAS study counted about 240,000 plastic particles per liter of bottled water — and roughly 90% were nanoplastics too small for older methods to see.
