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.

The study was prompted by earlier research by a separate group in Mexico that noted significant differences in brain samples collected from children and young-adult accident victims in smog-laden Mexico City compared with those in Veracruz, which has cleaner air. The brain tissue collected in Mexico City showed more extensive inflammation, oxidized DNA and other pathological markers of Alzheimer’s disease, Morgan said.
