A university is leading a projec that could change the way plants are used to help tackle the growing problem of air pollution.

Middlesex University, in The Burroughs, Hendon, has been chosen as a partner in a project run by the Mayor of London to monitor the effect of green living by creating walls made of plants.

The university’s school of science and technology has designed walls made of plants at a school in Barking and Dagenham.

Environmental health MSc student Alan Nicholls will now test the site to study the effects of the 'green walls' and see if they are useful in reducing harmful particles from the environment.

Senior biosciences lecturer Dr Dirk Wildboer said: "One of the objectives of our research is to be open-minded about it and generate more scientific data to see how good green walls are in mitigating air pollution and if they offer value for money.”

The project is due to be completed by early 2015.
