Samples from a remote lake at Snowdon contains micro plastic. Environmentalists says this is a wakeup call. Experts think the particles could have been deposited by rain.
The samples were collected by activist Laura Sanderson. She swam 16 miles (26km) from the source of River Glaslyn – 2,000ft (610m) above sea level – to the sea last April to collect the samples. The analysis was done at School of Natural Sciences at Bangor University. The full extent of the pollution is expected to be far worse.
Micro plastics are anything less than 5mm in size and nano-plastics that are only visible under a microscope. Snowdon is the highest mountain in Wales, at an elevation of 1,085 meters above sea level, and the highest point in the British Isles outside the Scottish Highlands.
