Kids who live in neighborhoods with heavy traffic pollution have lower IQs and score worse on other tests of intelligence and memory than children who breathe cleaner air, a new study shows.

The effect of pollution on intelligence was similar to that seen in children whose mothers smoked 10 cigarettes a day while pregnant, or in kids who have been exposed to lead, said Dr. Shakira Franco Suglia of the Harvard School of Public Health in Boston, the study's lead author.
