How do you study microplastics in a plastic-filled lab?

Apr 30, 2026 · 10m

Summary

Science Friday explores the complexities of measuring microplastics in the human body with Dr. Cassandra Routt from the University of Queensland. She explains how background contamination from lab equipment skews data and describes her stainless-steel "clean lab" designed to eliminate plastic interference. The discussion highlights the need for improved analytical techniques and global collaboration to accurately assess health risks, while noting that reducing plastic use also limits exposure to harmful chemical additives.
