Annual study finds that Phoenix's air quality is deteriorating

Annual study finds that Phoenix's air quality is deteriorating

The Eugene-Springfield area is now the 38th most polluted area in the USA for annual particle pollution, according to the American Lung Association's "State of the Air" 2019 report.

"Increased heat played a major role in the higher number of unhealthy air days" in the 2015-2017 period covered by the report, the American Lung Association states, chiefly blaming climate change.

As it has for the last 19 out of 20 years of the report, Los Angeles remained the most ozone-dense city in the US.

Since 1970, the USA has made significant progress in limiting air pollution - but recent cuts to the Environmental Protection Agency (EPA) threaten to halt decades of work against air pollution, according to the new American Lung Association report.

They say four in 10 Americans live in counties that have air with unhealthy levels of "particle pollution" or ozone. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution.

April's (not really) 'Pink Moon' rises on Good Friday
Tonight, at 7:12 p.m., continue your observance of Good Friday by finding a cozy spot with your loved ones and look up. For April, that meant wild ground phlox would bloom as spring's first blooms, which happened to be pink.


Kern County was No. 2 for most polluted by year-round particle pollution and was the No. 3 most ozone polluted city. The area also ended up at No. 17 for "short-term particle pollution". The report blamed California's destructive wildfires for the shift. California dominated the list of most-polluted cities.

Now more than ever the US must protect the Clean Air Act, according to the report.

Multnomah County scored a C for particle pollution.

"Congress must make certain that the Clean Air Act remains strong, fully implemented and fully enforced", the report said.
