A recent study at the University of New Mexico has found that there could be a spoon’s worth of microplastics in the human brain.

The study found that the extent of the harm to human health is unclear, although an increased inflammation and risk of future adverse cardiovascular events is likely.

Producer Amani spoke to Senior Lecturer of Chemical Sciences at the University of Auckland, Dr Joel Rindelaub, about the prevalence of microplastics in the human body, and what its impacts might be.
