King's research highlights that air pollution fell by 89% for the London Marathon
Posted on 24/04/2018
Measurements taken by researchers at King's College London during the London Marathon highlighted an 89% drop in air pollution levels in the capital.
By testing for levels of nitrogen oxides (NOx) for a 12 hour period on Sunday 22 April, then comparing these levels with previous Sunday levels for the same length of time, the research shows the impact that a wide-scale ban on polluting vehicles could have on the city.
The research comes two months before Clean Air Day 2018, which seeks to highlight the effects of air pollution, and adds to King's College London's ongoing work to tackle the problem of air pollution in London, including being one of six universities to run a recently announced monitoring supersite.
The new 'supersites' will have advanced air quality monitoring instruments with the ability to detect harmful air pollutants and their sources in greater detail than ever before. Researchers will be able to gather high-quality data on the content of harmful urban air pollution and where the gases and particles that pollute our air are coming from.
David Green from the Environmental Research Group, who will lead on the project, said: “The Environmental Research Group has been running the only two research ‘supersites’ in the UK - in Kensington and Westminster. The proposed new site in London will help measure the physical and chemical composition of particles, the toxic gases in the atmosphere’s greenhouse such as carbon dioxide and methane.”
