Sea salt around the world is contaminated by plastic, studies show

• We are living on a plastic planet. What does that mean for our health?

Sea salt around the world has been contaminated by plastic pollution, adding to experts' fears that microplastics are becoming ubiquitous in the environment and finding their way into the food chain via the salt in our diets.

Following this week's revelations in the Guardian about levels of plastic contamination in tap water, new studies have shown that tiny particles have been found in sea salt in the UK, France and Spain, as well as China and now the US.
