Denver Ozone Ranked 11th Worst In US

Judith QuinnАпр 21, 2017

"As we move into an ever warmer climate, cleaning up these pollutants will become ever more challenging, highlighting the critical importance of protecting the Clean Air Act", Wimmer said.

On the downside, although year-round pollution has improved, short-term spikes of severely polluted air have increased.

Orange maintained its "A" rating for having no high particle pollution days.

The cities with the worst year-round particle air pollution were Visalia-Porterville-Hanford, Calif., Bakersfield, Calif., Fresno-Madera, Calif., San Jose-San Francisco-Oakland, Calif., Los Angeles-Long Beach, Calif., Modesto-Merced, Calif., El Centro, Calif., Pittsburgh-New Castle-Weirton, Pa. -Ohio-W.Va., Cleveland-Akron-Canton, Ohio and San Luis Obispo-Paso Robles-Arroyo Grande, Calif. Westchester County had an "F" for high ozone days, the same as previous year.

Particle pollution is a combination of both minuscule liquid and solid particles circulating in the air. Ground-level ozone, a main ingredient of smog, has harmful effects, especially on children, older adults, people with respiratory illnesses, and those who work outdoors.

San Diego County's air quality has dramatically improved since the year 2000. "It's all trapping and not dispersing air pollution that normally would when we have weather conditions".

The report says breathing unhealthy air can put residents at risk for asthma attacks, worsened COPD symptoms and cardiovascular harm.

Ozone - created through chemical reactions from pollutants emitted by vehicles, power plants, gasoline vapors and other sources - is a larger problem for the Northeast than the more insidious particle pollution, which has been linked to a higher risk of cancer death.

While the number of days that the Bay Area as a whole experienced unhealthy levels of particle pollution is not contained in the report, the region is listed as being the nation's sixth-worst for short-term spikes in particulate matter and fourth-worst for year-round totals.

The report, released Wednesday, found that six of the 10 cities with the worst short-term air pollution in the US are in California.

Each year the lung health advocacy group issues a nationwide report card highlighting trends in two main causes of outdoor air pollution: ozone pollution and particle pollution.

According to the 2017 report, one-quarter fewer people live where the air quality hit unhealthy levels in 2013-2015 than in the 2016 report. President Donald Trump has proposed cuts to federal climate science funding and has deregulated industries that are a major source of unsafe emissions. This law has driven improvements in air quality for 47 years, improvements that the "State of the Air" 2017 continues to document.

"Imperial County has five monitors which measure the pollution, whether its ozone and also PM 2.5, PM 10", Lugo said.

In Trump's budget proposal, the agency's budget will be cut by 31% that would include weakening or eliminating the Clean Air Act, which, according to the report, it has been the most important tool in the fight for healthy air by driving emission reductions for more than 47 years.
