Greenpeace volunteers and scientists are collecting water samples from three different points along the Mersey using a filtering device called a manta net.

The samples will then be sent back to the University of Exeter, where they will be analysed using fourier-transform infrared spectroscopy (a cutting-edge infrared plastic detector) and compared with samples from other major rivers across the UK. The results will be collated into a scientific report on the plastic load in UK rivers to be released later this year.

Microplastics – very tiny plastic particles that come from degraded plastics and synthetic clothing – can be toxic to wildlife and fragile ecosystems and represent a vast proportion of the plastics that flow directly from our rivers out into the sea.

Greenpeace is calling on the UK government to tackle our plastic crisis by setting new legally-binding targets in the forthcoming Environment Bill to radically reduce single-use plastics. Greenpeace is also urgently calling on the government to create an independent environmental watchdog to ensure that these and other vital targets are met.

Kirsten Thompson, Lecturer in Ecology at University of Exeter says:

“This is the first nationwide investigation into micro plastic pollution in Britain’s major rivers.

There are a lot of studies showing how much plastic is in our seas and oceans, but very few so far investigating the amounts and types of plastics, especially microplastics, carried along by our rivers.

Documentaries like Blue Planet have shown us just how detrimental plastic pollution is to marine wildlife, but we hope that our research on rivers in England, Scotland, Wales and Northern Ireland will help uncover exactly where  this plastic is coming from and what impact plastic pollution may be having closer to home on creatures like otters, kingfishers and water voles.”

Fiona Nicholls, Greenpeace UK plastics campaigner said:

“More frightening facts seem to emerge about plastic pollution every month. It’s in our water, our food, the air; it’s polluting the most remote parts of our planet. But the scariest fact is that if we carry on with business as usual plastic production is set to quadruple by 2050. It’s clear our rivers and oceans simply can’t stomach this. That’s why Greenpeace is urging the government to ensure that their new Environment Bill sets specific targets for reducing the amount of throwaway plastic being made.”
