The World Health Organization is to launch a review into the potential risks of plastic in drinking water.
It will assess the latest research into the spread and impact of so-called microplastics – particles that are small enough to be ingested.
It comes after journalism organisation Orb Media found plastic particles in many major brands of bottled water.
There is no evidence that microplastics can undermine human health but the WHO wants to assess the state of knowledge.
