Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents. When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog. ... Ozone can also cause itchy, burning eyes.

Does car exhaust damage the ozone layer?
The effects of car pollution are widespread, affecting air, soil and water quality. Nitrous oxide contributes to the depletion of the ozone layer, which shields the Earth from harmful ultraviolet radiation from the sun.
How does factories affect the ozone layer?
Chemicals used as refrigerants, such as chlorofluorocarbons (CFCs), contain chlorine atoms. Releasing chlorine atoms into the atmosphere destroys ozone. A single chlorine atom can destroy thousands of ozone molecules.
How does ozone form from vehicle exhaust?
Automobile exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), by-products of burning gasoline and coal. NOx and VOC combine chemically with oxygen to form ozone during sunny, high-temperature conditions of late spring, summer and early fall.
How does car exhaust affect the environment?
Car exhaust contains gases such as carbon dioxide that contribute to global climate change. Such gases trap heat in the atmosphere, creating a greenhouse effect that contributes to the warming of the Earth's atmosphere, causing widespread climate change.
What do cars release into the air?
Burning fossil fuels like gasoline and diesel releases carbon dioxide, a greenhouse gas, into the atmosphere.
How do cars cause global warming?
Highway vehicles release about 1.6 billion tons of greenhouse gases (GHGs) into the atmosphere each year—mostly in the form of carbon dioxide (CO2)—contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds of GHG. That's roughly 6 to 9 tons of GHG each year for a typical vehicle.
Which pollutant can deplete ozone layer?
Chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).
What does the ozone layer do usually and what happens when it is degraded?
ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. When they break down, they release chlorine or bromine atoms, which then deplete ozone.
What causes high ozone levels?
This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight. Ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach high levels during colder months.
What produces ozone gas?
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
How is ground-level ozone related to vehicle emissions?
Cars and gasoline-burning engines are large sources of volatile organic compounds (VOCs). ... View charts on sources of VOC and NOx emissions in New England. The sun's direct ultraviolet rays convert these emissions into ground-level ozone, which is unhealthy to breathe.
