London: The River Thames in London has some of the highest recorded levels of microplastics for any river in the world, scientists have estimated, adding 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, the BBC reported on Tuesday. Flushable wet wipes were found in high abundance on the shoreline forming wet wipe reefs.
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, the BBC quoted Professor Dave Morritt from Royal Holloway, as saying.
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.
Tiny bits of plastic have been found inside the bodies of crabs living in the Thames. Crabs contained tangled plastic in their stomachs, including fibres and microplastics from sanitary pads, balloons, elastic bands and carrier bags, the researchers said.
