What is Indoor Air Pollution?
Indoor Air Pollution refers to the presence of harmful or excessive quantities of substances within buildings, homes, or enclosed spaces. It is often found to be 2-5 times more concentrated than outdoor air pollution, posing significant health risks.
Historical Background
Awareness of indoor air pollution as a distinct health concern grew with studies linking specific indoor pollutants to respiratory and other health issues. In developing countries, the use of biomass fuels for cooking and heating has historically been a major contributor, while in developed nations, synthetic building materials and reduced ventilation in energy-efficient buildings became concerns.
