Ozone Pollution

What is Ozone?

Ozone also known as trioxygen with the formula O3 is a naturally occurring gas related to oxygen. Formed and reacts under the action of light and that is present in two layers of the atmosphere. High up in the atmosphere, ozone forms a layer that shields the Earth from ultraviolet (UV) rays. 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) in the presence of sunlight.

Bad Ozone

Smog is a distinctive and easily recognizable form of urban air pollution. What we usually referred as smog is “bad” ozone. Ozone as a pollutant is formed by the combination of precursor pollutants such as emission from cars, factories, power or chemical plants with volatile organic compounds and the light from the sun (UV). While we are responsible for creating street-level or lower atmosphere ozone, the gas is hazardous to our health

Health Implications

Ozone is particularly harmful to our respiratory system it can create or worsen respiratory diseases, damage your lungs, and ultimately cause death. Ozone will have a different impact on different individuals. Scientific research shows ozone is harmful to asthmatic people, especially children, who can start expressing symptoms after only one hour of peak exposure. It can increase incidence and prevalence of nocturnal cough, respiratory infections, and asthma attacks.
