State of the Air 2014 for Arlington (top graph shows high particle pollution days and bottom graph shows high ozone pollution, or smog, days)Arlington’s air again received an “F” grade for smog from the American Lung Association’s annual “State of the Air” report, with days of high ozone pollution increasing over last year.

ALA’s last report in 2013 said that Arlington experienced an annual average of less than 10 days of smog that were “unhealthy for sensitive populations.” In the most recent study period, that number jumped to 11.2 days per year. A weighted average of four days is considered a passing grade.

However, the Lung Association says that Arlington received an “A” in its particle pollution grade, registering no 24-hour periods of unhealthy levels of particle pollution. Last year it received a “B” grade.

The D.C. area was the 8th-most polluted metropolitan area in the country, according to this year’s report, up from 9th last year and 14th in 2011. Los Angeles was again the most smog-filled metropolitan area.
