A world record not to be proud of.
The River Thames has some of the highest recorded levels of microplastics for any river in the world.
Scientists have estimated that 94,000 microplastics per second flow down the river in places.
The quantity exceeds that measured in other European rivers, such as the Danube and Rhine.
Tiny bits of plastic have been found inside the bodies of crabs living in the Thames.
And wet wipes flushed down the toilet are accumulating in large numbers on the shoreline.
Researchers at Royal Holloway, University of London, are calling for stricter regulations on the labelling and disposal of plastic products.
They warn that careless disposal of plastic gloves and masks during the coronavirus pandemic might make the problem of plastic pollution worse.
"Taken together these studies show how many different types of plastic, from microplastics in the water through to larger items of debris physically altering the foreshore, can potentially affect a wide range of organisms in the River Thames," said Prof Dave Morritt from Royal Holloway.
"The increased use of single-use plastic items, and the inappropriate disposal of such items, including masks and gloves, along with plastic-containing cleaning products, during the current Covid-19 pandemic, may well exacerbate this problem."
The scientists point out that the Thames is cleaner than it used to be with respect to some pollutants, such as trace metals.
Where does the plastic come from?
Fibres from washing machine outflows and potentially from sewage outfalls, plus fragments from the breakup of larger plastics, such as packaging items and bottles, which are washed into the river.
Katharine Rowley of Royal Holloway said it's unclear why there's such a high density of plastic in the River Thames, but called for people to think about the plastic they use and throw away.
"People can make much more of a difference than they might think," she said.
What is the plastic doing to wildlife in the river?
Some animals living in the river are ingesting microplastics, including two species of crab.
Crabs contained tangled plastic in their stomachs, including fibres and microplastics from sanitary pads, balloons, elastic bands and carrier bags.
"Upon bringing these crabs back to the labs at Natural History Museum, it was shocking to find that they were full of plastic," said study researcher, Alex McGoran.
"Tangles of plastic were particularly prevalent in the invasive Chinese mitten crab and we still don't fully understand the reason for this."
Clams near the wet wipe "reefs" contained synthetic polymers, some of which may have originated from the wet wipes and other pollutants found on the site such as sanitary items.
