Pollution in London • 4,000 Londoners a year die prematurely from causes related to air pollution. • Around 113 people die prematurely in Wandsworth every year from causes related to air pollution. • Air pollution contributes to many health problems including asthma, heart disease and lung disease and lung cancer.
• 80% of PM10s come from vehicles • Lancet July 2010 – there is a statistically significant association between risk for lung cancer and PM10 and 2.5
