A new study suggests that living close to busy freeways is related to your chance of getting heart disease. The study found a statistical correlation between exposure to diesel particulate matter — the exhaust from big trucks — and the thickening of plaque on the arteries, a pre-cursor of heart disease. The researchers concede, however, that their conclusions are weakened by a small sample size, and they report that the connection between the heart condition and exposure to pollution was greater among low-income people, suggesting that other factors, including diet or stress, could also be in play.
