Ground Level Ozone Basics Ground Level Ozone Pollution Ozone is a gas composed of three atoms of oxygen. ozone occurs both in the earth's upper atmosphere and at ground level. ozone can be good or bad, depending on where it is found. called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet. Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. ground level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems. epa regulations help states reduce ozone levels in outdoor air. learn more about ground level ozone.
What Is Ground Level Ozone Ground Level Ozone Formation Sources Ozone is found in two regions of the earth's atmosphere – at ground level and in the upper regions of the atmosphere. in both regions, ozone has the same chemical composition (o3). in the stratosphere six to 30 miles above the earth – ozone protects us from the sun's harmful rays. Within 3 years of epa issuing the standard, all states are required to submit sips with general infrastructure elements showing the state has the capacity to attain, maintain, and enforce a new or revised naaqs. these sip submittals must include the basic program requirements for managing air quality required in section 110 (a) (2) of the caa. Reducing ozone pollution makes breathing easier. the ozone molecule (o 3) is harmful to air quality outside of the ozone layer. epa regulations help states reduce ozone levels in outdoor air. 1 11 2021 epa proposes response to clean air act section 176a petition from maine. 12 23 2020 epa retains ozone national ambient air quality standards. Ozone acts as a protective layer high above the earth, but it can be harmful to breathe. breathing ground level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion.

Ozone at ground level is a harmful air pollutant, because of its effects on people and the environment, and it is the main ingredient in “smog." learn more about air emission sources. ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach high levels during colder months. National ambient air quality standards (naaqs) for ground level ozone, or ozone pollution, specify a maximum allowed measurement for ozone (o 3) to be present in outdoor air. limiting ozone pollution in the air protects human health and the environment. in december 2020, epa decided to retain the current ozone standards set in 2015:.
