Tropospheric Ozone (O3)

Definition

Tropospheric ozone, also known as ground-level ozone, is a secondary pollutant formed by the reaction of sunlight with nitrogen oxides and volatile organic compounds in the presence of heat. It is harmful to human health and can cause respiratory issues, eye irritation, and reduced lung function.

Analogy

Imagine tropospheric ozone as a mischievous invisible gas that likes to play pranks on your respiratory system. It's like a prankster hiding around corners, waiting to surprise you with coughing fits and irritated eyes.

Photochemical Smog: A type of air pollution resulting from the interaction between sunlight, nitrogen oxides, and volatile organic compounds, leading to the formation of tropospheric ozone.

Stratospheric Ozone Layer: A layer of ozone high up in the Earth's atmosphere that protects us from harmful ultraviolet (UV) radiation.

VOCs (Volatile Organic Compounds): Organic chemicals that easily evaporate at room temperature; they are precursors for tropospheric ozone formation when combined with nitrogen oxides under sunlight.
