Alleged Benefits of Tropospheric Ozone Don’t Hold Up, February 13, 2002
Opponents of the eight-hour ozone NAAQS have made unsupported claims that air pollution may have a beneficial effect on human health due to its alleged ability to reduce exposure to ultraviolet radiation from the sun.
In comments filed with EPA, the American Lung Association® points out that the data purporting to quantify tropospheric ozone benefits fails to meet the minimum standards of reliability and scientific adequacy.
“One tropospheric ozone benefits quantification calculation was presented orally by U.S. Department of Energy staff, and was never published or peer reviewed either internally at EPA or externally. The other quantification analysis of tropospheric ozone benefits is a draft that was never published,” states the comments.
The American Lung Association® supports EPA’s proposed decision to reject weakening of the 1997 0.08 ppm NAAQS based on alleged benefits of tropospheric ozone. A copy of the comments is attached.
