- Biological contaminants like pollen and mold.
- Tobacco smoke
- Pesticides and household products.
- Gases such as carbon monoxide and random.
- Materials used in the building such as lead, formaldehyde and asbestos.
Sick building syndrome occurs when several people are affected, but no specific source of the illness and disease are found. Indoor air quality problems usually only cause discomfort, and most people feel better as soon as they eliminate the source this pollution. However, some pollutants can cause diseases that show up much later, such as respiratory diseases or cancer. Making sure that your building is well-ventilated and eliminating pollutants can improve the quality of your indoor air.
The pollutants that can affect air quality in a home fall into the following categories:-
Particulate matter includes dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
Gaseous pollutants come from combustion processes. Sources include gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.
