    The second "Ozone Alert Day" of 2017 was issued for Thursday, August 3rd, meaning that the lower layer of the ozone has reached or will reach unsafe health levels.

    The first "Ozone Alert Day" of 2017 was June 8th.

    Typically in Tulsa and surrounding areas, the "ozone awareness" season falls from May to September, or the hottest months of the year. What happens during these months, is that the summer-time heat "cooks" ground-level pollutants leading to the "bad" layer of ozone. These pollutants can include chemical reactions from different gasses and the sunlight, emissions from industrial facilities and utilities, motor exhaust and gasoline vapors.

    If the measurements of these pollutants are above a safe level deemed by the EPA, then an Ozone Alert is issued for the area. 

    Long-term or repeated exposure to high levels of ozone may lead to some health problems, especially for the young, elderly, and those with pre-existing respiratory problems. It is possible to experience reduced lung function and increase respiratory discomfort.
