New debate questions how solid the evidence is for microplastics in human tissues
TL;DR Summary
A growing critique argues that many studies claiming microplastics in human bodies may be flawed, due to Py-GC-MS measurement flaws that can mistake tissue fats for plastics, and inadequate contamination controls. Critics point to 18 papers with questionable methods, highlighting that the field is nascent and that hard proof of health impacts is still lacking, though the possibility of plastics in humans isn’t fully ruled out.
