‘Superplant’ shrub absorbs 20pc more pollution than other hedges

The Daily Telegraph and iNEWS report one metre of dense hedge will mop up the same amount of pollution that a car emits over a 500-mile drive. Plant scientists at the Royal Horticultural Society have advised growers choose bushy, hairy-leafed alternatives, as these have been found to remove more air pollution.

Researchers tested three hedges for pollution removal in traffic hostpots;  Cotoneaster franchetii, Thuya plicata (Western red cedar) and Crataegus monogyna (hawthorn). They found that the cotoneaster franchetti was by far the most effective at cleaning the air, and that in just seven days a one metre length of well-managed dense hedge will mop up the same amount of pollution that a car emits over a 500 mile drive. 

Raw sewage dumped into English and Welsh beaches ‘2,900 times this year’

The Guardian reports water companies discharged raw sewage into bathing water beaches almost 3,000 times in the past year, polluting the environment and risking public health, new analysis shows. The study by Surfers Against Sewage, which publishes data on sewage releases as they occur, examines the notifications by water companies of effluent discharges over 12 months. 

No river in England is free from chemical pollution, government report finds

The Daly Telegraph,  BBC NewsThe Guardian, and The Financial Times report all of England’s rivers have failed their pollution quality tests, meaning the country’s waterways are some of the dirtiest in Europe. The report from Defra found that no river in England is free from chemical pollution. New sampling methods from the Environment Agency found that in all surface water sampled, persistent chemicals were present and being consumed or absorbed by aquatic life.

Pollution: Birds ‘ingesting hundreds of bits of plastic a day’

BBC News reports birds living on river banks are ingesting plastic at the rate of hundreds of tiny fragments a day, according to a new study. Scientists say this is the first clear evidence that plastic pollutants in rivers are finding their way into wildlife and moving up the food chain. Pieces of plastic 5mm or smaller (microplastics), including polyester, polypropylene and nylon, are known to pollute rivers. Researchers at Cardiff University looked at plastic pollutants found in a bird known as a dipper, which wades or dives into rivers in search of underwater insects.
