Ozone is a molecule, a gas at normal atmospheric temperatures. It is harmful for humans to breathe too much in each breath, so when it is in the air we breathe, we call it a pollutant. When it is above our heads, we call it "the ozone layer" and it protects us from UV-B from our Sun. "pollutant" and "pollution" are valueless labels. If you live in a place that only ever gets 7 inches of rainfall each year, and you have a population that requires 8 inches of rainfall a year, they call it a "drought" when they don't get 8 inches of rainfall. Valueless label.
No, Ozone is not a primary pollutant, it is a pollutant near ground level. However, it keeps many ultraviolet rays from reaching the Earth.
Secondary Pollutant
A secondary pollutant is one that is not directly emitted by a point source. Ozone is not directly emitted - it requires the sun to form. It forms as a result of direct pollutants such as NO2 and volatile organic compounds.
Ozone
Both the classic London smog (sulfur dioxide, fog and particulates) and the present photochemical smog (ozone, PAHs, hydrocarbon and nitrogen oxides oxides) are air pollution resulting from primary air emissions like hydrocarbons, sulfur dioxide, nitrogen oxides.
Ozone is a pollutant. It is at ground level a pollutant.
Ozone
Ozone is considered to be the most common air pollutant in the United States.
No, it is not. The ozone in stratosphere is good ozone.
Ozone is good at atmospheric level. It is pollutant in ground level.
ozone
Yes, in the troposphere, ozone is a pollutant.
In general no. Ozone is a product of pollution, and is itself considered a pollutant.
Greenhouse gases destroy ozone. They can cause ozone depletion.
Ozone is produced at ground level which is a pollutant. it is made by thunder and lightening.
At the ground level, yes. It acts as a pollutant.
Yes, it is. But only ground ozone is pollutant.
