Ozone
Ozone Ozone (O₃) is a gas formed in the atmosphere through chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOₓ) in the presence of sunlight. It plays a dual role in the environment: in the stratosphere, ozone forms the ozone layer, which protects life on Earth by absorbing harmful ultraviolet radiation. However, at…

Nitrogen Oxides
Nitrogen Oxides Nitrogen Oxides (NOx) is a group of reactive gases primarily composed of nitric oxide (NO), a colorless, odorless gas, and nitrogen dioxide (NO₂), a reddish-brown gas with a pungent odour. NO forms during high-temperature combustion processes and reacts with oxygen or ozone in the air to create NO₂. NOx contributes to air pollution,…
