On Sunday, August 5, 2018, the Arizona Daily Star printed another ozone scare story titled “Tucson’s air pollution violates federal ozone standards for the first time.” (Link)
The story notes that measured ozone at one station, Saguaro Park-East, hit 75 parts per billion, compared to a federal standard of 70 parts per billion, over an eight-hour period. That puts a three-year average at 71 parts per billion which violates Federal standards. While this may have some compliance penalties, the Star story’s main thrust was potential health problems.
Last year, the same monitoring station also exceeded the 70ppb limit. I wrote an article on July 2, 2017, about the previous Star story (“Tucson-area air quality the worst in five years.”) Within my story I note:
“For many years, the EPA has been conducting experiments on the effects of ozone exposure. They place volunteers in a closed room and subject them to 300ppb to 400ppb ozone for two hours while they performed mild exercise. The 6,000 volunteers included children, the elderly, and even asthmatics. The EPA reports that ‘not a single adverse event.. [was] observed.’” (Source)
