Scientists have made a disturbing discovery: human brains contain microplastics, and at higher concentrations than other organs. Worse, brain levels have jumped 50% in just eight years.
The original paper about microplastics in the brain seems to have a serious methodological flaw that undermines the conclusion that our brains are swimming in microplastics.
“False positives of microplastics are common to almost all methods of detecting them,” Jones says. “This is quite a serious issue in microplastics work.”
Brain tissue contains a large amount of lipids, some of which have similar mass spectra as the plastic polyethylene, Wagner says. “Most of the presumed plastic they found is polyethylene, which to me really indicates that they didn’t really clean up their samples properly.” Jones says he shares these concerns.
This is from other microplastics researchers. See this article. So before we panic about this, let’s wait for some independent replication and more agreement in the scientific community.
Microplastics are a serious concern, and we need to deal with plastic pollution. Let’s just stick to high quality science while we do that.

Thank you for the nuance. Bad data and hyperbole doesn’t help what I agreed is a serious issue.
Psypost is like the the Daily Mail of science journalism. Kind of just dismiss everything I see from them at this point. Thank you for the rebuttal.
