When arteries become clogged by traffic air pollution

Living near a busy road can cause heart disease, research claims.
Long-term exposure to air particles from traffic pollution can cause clogging of the arteries, known as atherosclerosis, according to a study. Studying 5,000 participants with an average age of 60, researchers - who presented their findings at a conference in Rome, Italy - looked for a link between heart disease and proximity to major roads.
They determined that the closer you lived to heavy-traffic roads, the higher your level of calcium around the heart - potentially causing a condition known as aortic calcification. For every 300ft you are closer to major traffic, levels increased by 10 per cent, the study found.
