indoor pollution factsIMPORTANT
Some people react to indoor air contamination by coughing or sneezing and things like that, but the symptoms go away as soon as they leave the building. For others, there are more serious effects, especially if they are exposed to the contamination for a longer period.

Indoor Air Pollution

‘Indoor air’ is air within a building such as your home, classroom, office, shopping center, hospital or gym. We say ‘Indoor Air Pollution’ if indoor air is contaminated by smoke, chemicals, smells or particles.

Unlike outdoor air pollution, the effect of indoor air pollution is health related and less of an environmental issue. In colder regions, building and heating methods make use of airtight spaces, less ventilation and energy efficient heating. Sometimes synthetic building materials, smells from household care and furnishing chemicals can all be trapped indoors. As less fresh air gets indoors, the concentration of pollutants such as pollen, tobacco smoke, mold, pesticides, radon, asbestos and carbon monoxide trapped inside the building increases and people breathe that in.

Common indoor air pollutants include:

Tobacco smoke:
This is smoke burning cigarettes or exhaled smoke by people smoking.
Biological Pollutants:
These include allergens such as pollen from plants, hair from pets, fungi and some bacteria.
This is a gas that is naturally emitted from the ground. Radon can be trapped in basements of building and homes. The gas is known to cause cancer after exposure over a period.
Carbon Monoxide:
This is a poisonous gas with no color or smell. Carbon monoxide is produced when fuels such as gas, oil, coal or wood do not burn fully.
