This is real and important — a University of Michigan research team just published a study finding that lab gloves contaminate microplastic measurements in ways that make current estimates look way too high. They traced the culprit to stearate salts, a release agent used in glove manufacturing, which looks structurally similar to actual plastic under the microscopy tools scientists use. The finding is peer-reviewed, freshly published (March 26, 2026), and explains why they were getting plastic counts 1,000 times higher than expected. This doesn't mean microplastics aren't a real problem — it means researchers may be significantly overstating how much is actually out there.
