Studies detecting microplastics throughout human bodies have made for alarming reading in recent years. But last week, the Guardian’s environment editor, Damian Carrington, reported on major doubts among a group of scientists about how some of this research has been conducted. Damian tells Ian Sample how he first heard about the concerns, why the scientists think the discoveries are probably the result of contamination and false positives, and where it leaves the field. He also reflects on how we should now think about our exposure to microplastics. Help support our independent journalism at theguardian.com/sciencepod
