Small increases in air pollution that are well below current safety limits can raise the risk of lung cancer and heart attacks, according to two new studies.
Researchers found that long term exposure to microscopic particles of soot at levels similar to those found in suburban areas of Britain can increase the risk of lung cancer by up to 36 per cent.
The short term impact of the same levels of these sooty particles, which are produced by diesel exhausts, also increased the risk of being admitted to hospital or dying from heart failure by two per cent.
The particles, which are more than 100 times small than a human hair, can become lodged in the lungs and pass through into the blood stream, causing inflammation.
The scientists behind the two studies say that their findings indicate that current safety limits on air pollution are still too high and need to be lowered.
