Microplastics are turning up everywhere; in our lungs, blood, even our brains. They’re tiny, toxic, and almost impossible to avoid. So what can we do about them? Today, Emma Kennedy speaks to Dr Antaya March and Prof Fay Couceiro from the University of Portsmouth to find out what this means for our health and the long term consequences of ignoring this tiny problem.
