FAQs
Ground-level ozone comes from pollution emitted from cars, power plants, industrial boilers, refineries, and chemical plants. Ozone pollution can even come from paints, cleaners, solvents, and motorized lawn equipment.
What are the major air pollutants of ozone? ›
Ozone is good up high, bad nearby. The ozone layer found high in the upper atmosphere shields us from much of the sun's ultraviolet radiation. However, ozone air pollution at ground level where we can breathe it causes serious health problems. Ozone aggressively attacks lung tissue by reacting chemically with it.
What primary pollutants react to ground-level ozone? ›
Ground-level ozone is a colorless and highly irritating gas that forms just above the earth's surface. It is called a "secondary" pollutant because it is produced when two primary pollutants react in sunlight and stagnant air. These two primary pollutants are nitrogen oxides (NOx) and volatile organic compounds (VOCs).
What is the most common name for ground-level ozone pollution? ›
Tropospheric, or ground level ozone, is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC).
What are the six primary sources of ground-level ozone pollution? ›
Ground-level ozone is formed from the reaction of oxygen-containing compounds with other air pollutants in the presence of sunlight. The main sources of ozone are trucks, cars, planes, trains, factories, farms, construction,and dry cleaners.
Is ground-level ozone bad? ›
Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs. Repeated exposure may permanently scar lung tissue.
What are the top 4 air pollutants? ›
Ozone (O3) Nitrogen dioxide (NO2) Carbon monoxide (CO) Sulphur dioxide (SO2)
What are the secondary pollutants of ground-level ozone? ›
Ground-level ozone is a secondary pollutant formed through chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs). Ozone can irritate the eyes, nose and throat, aggravate lung diseases, or increase the risk of premature death in people with heart or lung disease.
What air pollutants is ozone likely to be formed? ›
The most significant things that cause ground-level ozone to form are: NOX and VOCs (from mobile source emissions and industrial processes ), and. UV radiation (from sunlight).
What are the symptoms of being exposed to ozone? ›
Ozone (O₃) is a colorless to blue gas with a pungent odor. Exposure to ozone may cause headaches, coughing, dry throat, shortness of breath, a heavy feeling in chest, and fluid in the lungs. Higher levels of exposure can lead to more severe symptoms. Chronic exposure may lead to asthma.
At abnormally high concentrations (the largest source being emissions from combustion of fossil fuels), it is a pollutant, and a constituent of smog. Its levels have increased significantly since the industrial revolution, as NOx gasses and VOCs are some of the byproducts of combustion.
What are the most common ozone destroying pollutants? ›
What ozone depleting substances are
- chlorofluorocarbons (CFCs)
- hydrochlorofluorocarbons (HCFCs)
- hydrobromoflurocarbons (HBFCs)
- halons.
- methyl bromide.
- carbon tetrachloride.
- methyl chloroform.
What are the 5 main ozone-depleting sources? ›
ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform. ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere.
Why does Colorado have so much ozone? ›
Vehicles that run on gas, other equipment that runs on gas, and industry operations are all large sources of ozone precursors in Colorado.
What air pollutants should be controlled to reduce ground-level ozone? ›
Ground-level ozone comes from pollution emitted from cars, power plants, industrial boilers, refineries, and chemical plants. Ozone pollution can even come from paints, cleaners, solvents, and motorized lawn equipment.
What pollutes the ozone the most? ›
Ground-level ozone comes from pollution emitted from cars, power plants, industrial boilers, refineries, and chemical plants. Ozone pollution can even come from paints, cleaners, solvents, and motorized lawn equipment.
What are the 3 most common ozone-depleting substances? ›
Ozone depleting substances include: chlorofluorocarbons (CFCs) hydrochlorofluorocarbons (HCFCs) hydrobromoflurocarbons (HBFCs)
What are the major air pollutants? ›
Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. Outdoor and indoor air pollution cause respiratory and other diseases and are important sources of morbidity and mortality.
