INTERVIEW

Pervasive plastic contamination and unreliable methods have clouded the science on microplastics in the human body. In an interview, Australian scientist Cassandra Rauert, who built a plastics-free lab to study human exposure, explores the challenges for researchers.

Scientists have been documenting the presence of microplastics in our oceans and soils, in air, drinking water, and food for more than a decade. More recently, peer-reviewed studies have revealed the presence of microplastics in the human body. But how much plastic do we consume, where is it coming from, and what is it doing to us?

Cassandra Rauert, an environmental chemist at the University of Queensland, in Australia, conducts research to better understand the impacts of such exposures. Her work has shown that current techniques used for detecting plastic in humans are vulnerable to contamination from lab equipment.…
