3 Health studies on ozone are “iffy” at best. I have read many scientific papers on the impacts of ozone on humans and most do not include very important factors such as daily allergy reports, how long the people were actually outside during a high ozone event and whether they are smokers, etc. I have never been negatively impacted by any of the San Antonio high ozone events. My challenge in breathing comes during high pollen events, smoke from agricultural burning in Mexico and Central America and Saharan dust.Cities in the south are unfairly labeled “non-attainment “, due to our geographic location.
4. Since most high ozone events occur during hot days with clear skies, cities in the south should be allowed more high ozone event days than those in the north. There many more days of 80 degrees plus temperatures in southern states than northern states. Our odds of having a high ozone event are greater, even if we have the same emissions as cities to our north.
