The invisible chemistry of the air inside your home
In short: We often focus on outdoor smog, but the air indoors contains a complex mix of natural, human-made, and combustion-based pollutants. This video breaks down the primary culprits found in indoor environments.
The lesson categorizes indoor pollutants into three distinct origins. Natural sources include substances like radon, dust, and mold. Human-made pollutants are often chemical in nature, such as formaldehyde and Volatile Organic Compounds (VOCs).
Additionally, pollutants resulting from combustion processes contribute significant risks, including tobacco smoke, particulates, sulfur dioxide, nitrogen oxides, and carbon monoxide.
