Each year over 17 million people die due to cardiovascular diseases. Behavioural risk factors such as smoking and a poor diet are known to increase the risk of dying from CVD but air pollution is not considered such a risk because of uncertainty as to how exposure to air pollution can be modified.
Last year, The Royal College of Physicians of Edinburgh recommended that air quality monitors should be placed at all Scottish city primary schools for a period of at least one year, followed by a similar monitoring of all urban secondary schools.
