The American Lung Associations State of the Air 2012 report finds that Denver metro area and northern Front Range counties received mixed grades for smog and soot, compared to last year's air quality report.

It can cause immediate health problems and continue days later. Ozone can cause wheezing, coughing, asthma attacks and premature death.When comparing the 2012 State of the Air Report to last years grades for ozone pollution:
Adams Countys grade improved from a D to a C.
Arapahoe Countys grade did not change from a C.
Boulder Countys grade improved from an F to a D.
Denver Countys grade improved from a C to a B.
Douglas Countys grade did not change from an F.
Jefferson Countys grade did not change from an F.
Larimer Countys grade did not change from an F.
Weld Countys grade did not change from a C.
"Particle pollution can be deadly," Swalnick said, referring to soot in the air. "When you breathe particle pollution, you are inhaling a toxic mix of chemicals, metals, aerosols, ash and diesel exhaust. It can cause asthma attacks, heart attacks, strokes, emergency room visits and even premature death. There is absolutely no question regarding the need to protect public health from particle pollution."When comparing the 2012 State of the Air Report to last years grades for 24-hour particulate pollution:
Adams Countys grade improved from a C to an A.
Arapahoe Countys grade improved from a B to an A.
Boulder Countys grade did not change from a B.
Denver Countys grade improved from a C to an A.
Douglas Countys grade improved from a B to an A.
Larimer Countys grade did not change from an A.
Weld Countys grade improved from a C to a B.
Fort Collins-Loveland tied for 12th among the country's cleanest cities for short-term particulate pollution. All counties in Colorado passed for annual levels of particulate pollution."The Denver metro area has significantly reduced ozone pollution levels in recent years thanks to the commitment of industry, local governments and individual citizens to produce less ozone-causing emissions," said Ken Lloyd, executive director of the Regional Air Quality Council. "However, an increased effort will be required to continue to improve our air and to meet current and upcoming standards. There is something that everyone can do to contribute."This year's report details the trend that standards set under the Clean Air Act to clean up major air pollution sources -- including coal-fired power plants, diesel engines, and sport utility vehicles -- are working to drastically cut ozone and particle pollution from the air, the association said.However, the association stressed that more than 40 percent of people in the United States live in areas where air pollution continues to threaten their health.Those at greatest risk from air pollution include infants, children, older adults, people with asthma and other lung diseases, as well as people with heart disease or diabetes, people with low incomes and those who work or exercise outdoors.
