London’s pollution killed 9,500 people in 2010, the first study to quantify the full danger showed, prompting Mayor Boris Johnson to renew his calls for abandoning the expansion of Heathrow Airport on air quality grounds.
About 5,900 deaths were the result of nitrogen dioxide, a pollutant produced by diesel engines, according to the report released Wednesday by King’s College London for the mayor’s office. The remainder were due to particulate pollution known as PM2.5s.
