An air sample is pulled through a calibrated size chamber, and UV of wavelength 254 nm is passed through that gas stream. The intensity of the light source is periodically calibrated, and the intensity received across the chamber is measured. The "Beer Lambert law" is used to infer the amount of ozone present in the chamber, and the "pollution level" is then known. Other methods are being researched.
Ozone is a pollutant. It is at ground level a pollutant.
The ozone at ground level is a pollutant. It acts as a secondary pollutant.
Ozone is good at the stratospheric level. It is a pollutant at ground level.
Ground level ozone is a pollutant. it is generally emitted from vehicles.
Ozone at the ground level acts as a pollutant. It also accounts for the greenhouse effect.
Ozone is good at atmospheric level. It is pollutant in ground level.
Ozone is yes a pollutant at ground level. It causes carious respiratory problems.
Ozone is bad at the ground level. IT is a pollutant.
No, Ozone is not a primary pollutant, it is a pollutant near ground level. However, it keeps many ultraviolet rays from reaching the Earth.
Yes, ozone can. Ozone is a pollutant at ground level.
The ground level ozone is a pollutant. It is release from vehicle exhaust.
The ozone has ill effects at ground level. It is a pollutant.
