Tiny shards of plastic are increasingly infiltrating our brains, study says – CTV
Aug. 26, 2024
Human brain samples collected at autopsy in early 2024 contained more tiny shards of plastic(opens in a new tab) than samples collected eight years prior, according to a preprint posted online in May. A preprint is a study which has not yet been peer-reviewed and published in a journal.
“The concentrations we saw in the brain tissue of normal individuals, who had an average age of around 45 or 50 years old, were 4,800 micrograms per gram, or 0.5 per cent by weight,” said lead study author Matthew Campen, a regents’ professor of pharmaceutical sciences at the University of New Mexico in Albuquerque.
“Compared to autopsy brain samples from 2016, that’s about 50 per cent higher,” Campen said. “That would mean that our brains today are 99.5 per cent brain and the rest is plastic.”
