Why Nanoplastics in Drinking Water Are So Hard to Measure
Nanoplastics have been found in tap and bottled water, but the numbers are hard to trust. The real problem is measurement science, not just contamination.

What Plastics Are Actually in Your Body? The Polymer Breakdown
A 2024 systematic review mapped microplastics in human tissue: polyester leads, fibres dominate, and the particles inside us are smaller than those we track in food.

What's Actually in PVC Water Pipes — and Does It Reach You?
A federal ATSDR review traces the chemicals inside PVC drinking-water pipes. The headline finding: one plasticizer, DEHP, drives most of the risk — but it's nuanced.

When Microplastics Carry Cadmium: A Freshwater Crab Study
A 2026 study found microplastics and cadmium together stress freshwater crabs more than either alone — and that plastic type dictates which organ takes the hit.
