Can Py-GC-MS detect polyethylene and PVC in human blood?

Plastic Detection in Blood1 min readUpdated June 7, 2026

What the Evidence Shows

We analyzed the available evidence and found that current methods using pyrolysis–gas chromatography–mass spectrometry (Py-GC-MS) cannot reliably detect polyethylene or PVC in human blood. The issue isn’t that the technique is broken—it’s that the chemicals naturally present in blood, along with...
