With Middlesex University as academic partner, the Mayor of London’s Air Quality Fund sponsors a three-year research study on the effect of plants on improving air quality The University’s School of Science and Technology has built walls made of plants at Warren School, a secondary school in the borough of Barking and Dagenham. These will be used to study the efficiency of ‘green walls’ reducing harmful particles from the environment. It is estimated that in Greater London more than 4,000 deaths per year are caused by microscopic airborne particles emitted in exhaust fumes.
Earlier studies have proved that green walls help reduce these harmful pollutants as these particles stick to the leaves of plants. The Middlesex green wall project will contribute to the body of data surrounding this theory.
