Dr Joel Rindelaub: chemical scientist on microplastics being discovered in human brains - The Sunday Session with Francesca Rudkin

New research has revealed microplastics have infiltrated human brain tissue to a 'concerning' degree.

This adds to studies finding tiny shards of plastic in critical organs - as microplastics have been found in lungs, bone marrow, blood vessels, reproductive organs, livers and kidneys, to name a few.

Chemical scientist Dr Joel Rindelaub is unsurprised by this discovery.

"I'm not sure if these will be the final numbers, but there's some pretty good confidence that there's probably plastic in people's brains."
