Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A large body of work shows that exposure to road traffic and air pollution may be a trigger of adverse cardiovascular events such as angina, myocardial infarction, and heart failure, with long-term exposure increasing the lifetime risk of death from coronary heart disease. The research by the University of Edinburgh measured the impact of diesel exhaust fumes on healthy volunteers at levels that would be found in heavily polluted cities.
