People living near major roadways are about twice as likely to die from heart and lung diseases as those who live farther away from such sources of air pollution, according to a new study of almost 4,500 people. The increased risk for people living within 100 meters of a freeway or within 50 meters of some other major road was apparent to researchers even after adjusting the data for the effects of participants’ smoking, education, occupation, income, and weight.
