A TEAM of scientists from Scotland and France have found microplastics in a secluded area of the Pyrenees mountains.

The area, which is around 75 miles from its nearest major city and four miles from the closest village, is thought to have 365 tiny plastic fragments or fibres on every square metre of land.

The researchers stressed the microplastics must have been carried through the air to reach the location between France and Spain.

Steve Allen, from the University of Strathclyde said: “The fact that it can travel in the air is very worrying.

“It’s likely to be basically everywhere.

"Plastic litter is an increasing global issue and one of the key environmental challenges we face on global scale."

Allen added the likely culprit for the fragments was single-use plastics such as polystyrene or plastic bottles.

The study, published in the Nature Geoscience journal, looked at fibres up to 750 micrometres long, and fragments up to 300 micrometres in diameter.

Some of the fibres included were 10 micrometres in diameter – a size which can be inhaled by humans.
