Microplastic Found In Britain’s “Most Iconic” Rivers & Lakes – FoE

New research by Bangor University and Friends of the Earth claims to have found microplastic pollution in some of Britain’s most iconic and remote rivers and lakes. 

The study, which is believed to be the first of its kind, looked at ten sites – including lakes in the Lake District, waterways in the Loch Lomond and Trossachs National Park, a wetland and Welsh reservoir – and found microplastics in all of them, according to the report.

Friends of the Earth and Dr Christian Dunn, of Bangor University (who led the research) say the findings suggest that microplastics should now be considered as an emergent contaminant – and that routine monitoring of all UK waters must now take place.

Friends of the Earth is urging MPs to support new legislation, currently before Parliament, to phase out plastic pollution within 25 years – including an end to non-essential single-use plastic by 2025.

Dr Christian Dunn, of Bangor University – “Plastic is polluting our rivers, lakes and wetlands in a similar way as pollutants such as so-called ‘emerging contaminants’ like pharmaceutical waste, personal care products and pesticides.”

Using a fluorescence lighting system, researchers were able to identify and count microplastic pollutants (less than 5 mm in size) – such as plastic fragments, fibres and film – per litre of water.

The preliminary findings suggest microplastic pollution levels ranging from over a 1,000 pieces of plastic per litre in the river Tame in Greater Manchester, to 2.4 pieces per litre in Loch Lomond.

Last year, a report by Eunomia for Friends of the Earth, estimated that microplastic pollution is entering UK waterways from a number of sources every year. The key sources of pollution include car tyres (7,000-19,000 tonnes), clothing (150-2,900 tonnes), plastic pellets used to make plastic items (200-5,900 tonnes) and paints on buildings and road markings (1,400-3,700 tonnes), it says.

Friends of the Earth and Dr Christian Dunn says further work is now essential to “fully investigate” any health risks from microplastics – to humans and ecosystems – so that “safe” levels can be ascertained, and removal and mitigation processes can be put in place.

Although there have been a number of studies on plastic pollution in the marine environment and some on the sediment of waterways, less research has been conducted on microplastic pollution in actual water samples from inland systems in the UK, the study claims.

The researchers says the methodology used in this study offers a “simple, low-cost way of collecting and analysing samples, allowing regular nationwide monitoring of waterways”.

The waterways surveyed (including pieces of plastic per litre of water) were:
• River Thames, London (84.1)
• Chester reedbed (7.6)
• Ullswater, Lake District (29.5)
• River Irwell, Salford, Greater Manchester (84.8)
• River Tame, Tameside, Greater Manchester (>1,000)
• River Blackwater, Essex (15.1)
• Falls of Dochart, Loch Lomond & Trossachs National Park (3.3)
• Loch Lomond, Loch Lomond & Trossachs National Park (2.4)
• Afon Cegin – river; North Wales (76.9)
• Llyn Cefni – reservoir; Anglesey, Wales (43.2 )

“Startling”

Dr Christian Dunn, of Bangor University, said: “It was more than a little startling to discover microplastics were present in even the most remote sites we tested, and quite depressing they were there in some of our country’s most iconic locations. I’m sure Wordsworth would not be happy to discover his beloved Ullswater in the Lake District was polluted with plastic.

“These initial findings, from our team at Bangor University with Friends of the Earth, show that we have to start taking the issue of plastic in our inland waters seriously.

“Plastic is polluting our rivers, lakes and wetlands in a similar way as pollutants such as so-called ‘emerging contaminants’ like pharmaceutical waste, personal care products and pesticides.

Julian Kirby, plastics campaigner at Friends of the Earth – “MPs must get behind new legislation, currently before Parliament, that would commit the government to drastically reduce the flow of plastic pollution that’s blighting our environment.”

“As with all emerging contaminants we don’t yet fully know the dangers they present to wildlife and ecosystems, or even human health, and to what levels they occur in all our water systems.

“But it’s now clear that microplastics should be considered a serious emerging contaminant and there needs to be a concerted effort to regularly monitor all our inland waters for them.

“Our method provides a straightforward and low-cost way of doing this so we now need to roll it out and see if our preliminary results are just the tip of the iceberg.”
