Scrubbing the Air with Trees- London’s BRIDGE Program

Estimating the removal of atmospheric particulate pollution by the urban tree canopy of London, under current and future environments (Abstract, Matthew Tallis,  Gail Taylor, Danielle Sinnett, Peter Freer-Smith, Landscape and Urban Planning, Sep. 1, 2011)

From London comes research on the capability of trees in an urban setting to remove PM10 from the air through accumulation of it on their leaves or needles. The article under review also presents a method to estimate how future implications of climate change on air pollution may be mitigated using urban tree growth. Previous research on the link between trees and pollution suggested that some trees when exposed to heavy pollution, particularly near heavy traffic, add volatile organic chemicals to the pollution.
