Microplastics are infiltrating brain tissue, studies show 

‘There’s nowhere left untouched’

Twenty-four brain samples collected in early 2024 measured on average about 0.5% plastic by weight.

A growing body of scientific evidence shows that microplastics are accumulating in critical human organs, including the brain, leading researchers to call for more urgent actions to rein in plastic pollution.

Studies have detected tiny shards and specks of plastics in human lungs, placentas, reproductive organs, livers, kidneys, knee and elbow joints, blood vessels and bone marrow.

Given the research findings, “it is now imperative to declare a global emergency” to deal with plastic pollution, said Sedat Gündoğdu, who studies microplastics at Cukurova University in Turkey.

Humans are exposed to microplastics – defined as fragments smaller than 5mm in diameter – and the chemicals used to make plastics from widespread plastic pollution in air, water and even food
