The study was a first to attempt to look at how chronic health problems are linked to the degree of pollution across the neighborhoods of a major U.S. city, lead author, Michael Jerrett said.
The study, which will be published in the November issue of Epidemiology, found the risk of death rose by 11 to 17 percent from the cleanest parts of Los Angeles to the most polluted areas of Riverside and San Bernardino counties to the east.
The risk of fatal heart disease rose by between 25 percent to 39 percent as the concentration of fine particles in the neighborhood's air rose by a measure of 10 micrograms per cubic meter of air, the study showed.
Data from monitoring sites within Los Angeles show that the concentration of such airborne particles -- tiny specks of solids and droplets of acids and other chemicals -- rises by almost 20 micrograms per cubic meter as commuters head east from L.A.'s wealthier, westside neighborhoods.
