A study published in the British Medical Journal has claimed that traffic fumes can cause hearts attacks up to 6 hours after exposure. It seems prolonged exposure to pollutant particles and nitrogen dioxide can increase the risk of suffering a heart attack. Although the authors of the paper have identified the risk as small, there is only a 1.3% greater chance of a heart attack after six hours of exposure to the substances it can would still be enough to bring forward a heart attack which was about to happen anyway. It does seem the greater risk is mainly to those who have already been diagnosed with heart problems. I guess what we don’t need the paper to tell us is that traffic fumes are bad for us.
