Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore every aspect of our health and wellbeing.

In this episode, they delve into the issue of microplastics - minute fragments of plastic material that have been found in every environment on the planet, as well as in our brains and bodies. How did they get there, are they doing us harm and, if they are, what can we do about it? They speak to Environmental Toxicologist Dr Stephanie Wright from Imperial College, London about the evidence behind the dramatic headlines and why trying to measure the impact of microplastic on health is a challenge.
