State and local officials are putting their money where their mouth is as they seek the public’s help this summer to combat one dangerous form of air pollution — ground-level ozone.
According to the Arizona Department of Environmental Quality, ground-level ozone — distinguished from the “good” ozone found in Earth’s upper atmosphere — forms when chemicals in pollutants react with sunlight.
“Ground-level ozone, or the ‘bad’ ozone, forms closer to the Earth in the air we breathe. This ozone is not usually emitted directly, but rather forms from chemical reactions between oxides of nitrogen and volatile organic compounds in sunlight,” the agency explained at its website: azdeq.gov.
