Freeway air pollution linked to brain damage in mice

It is well known that air pollution from cars and trucks on Southern California freeways -- a combination of soot, pavement dust and other toxic substances -- can cause respiratory disease, heart attacks, cancer and premature death. Now, exposure to pollution particles roughly one-thousandth the width of a human hair has been linked to brain damage in mice, including signs associated with memory loss and Alzheimer’s disease, according to a USC study in the journal Environmental Health Perspectives.
