Living in a city or near a busy highway could put people at risks for stroke and even memory loss, according to a new study in the Archives of Internal Medicine.

It found a higher risk of stroke after "moderate" compared to good air quality days in Boston-area residents, especially when traffic-related pollution was high.

They add one of the most important findings was that, even at levels that are considered to be safe by the EPA, doctors were seeing important health effects.

Another study in the same journal found a faster long-term decline in thinking and memory skills in women living in higher pollution areas of the U.S.
