Sorry Angelenos. You Can't have it All.

Los Angeles has the worst smog in the nation, despite California's tight environmental standards and years of progress fighting pollution, according to a new report by the American Lung Association.

The report, released on Wednesday, also said another California city, Fresno, has the highest level of pollution from particles in the air, mostly caused by vehicle exhaust.

"We've made significant improvements, but we still have a long ways to go," said John Balmes, a medical doctor and professor of Environmental Health Sciences at the University of California at Berkeley.

The Los Angeles metropolitan area had the highest levels of ozone pollution, or smog, formed by a combination of sunlight and other pollutants in the atmosphere, according to the report.

The report looked at levels of pollutants in major U.S. cities from 2010 through 2012. Results can be viewed at:

Outside of California, Houston, the Washington-Baltimore-area and Las Vegas had some of the worst problems with ozone pollution, which can create or worsen lung conditions like asthma, the report said.

Atlanta and Pittsburgh registered high levels of particle pollutants, which have also been linked to many health issues, including breathing difficulties and heart attacks.
