Carbon monoxide
Nitrogen dioxide
These are the highest, most dangerous indoor air pollutants; However, there are still some other less hazardous but still harmful ones.

Tobacco smoke

Smoking tobacco is the major cause of most indoor emissions which lead to various health effects. Second-hand tobacco smoke is associated with coronary heart disease and irritation, respiratory system diseases in adults. In children, it causes mid-ear infections and sudden death syndrome.


Lead is a common metal in our households as it is used to manufacture a lot of things. It was majorly used for paint manufacturing, but it has since been banned. This is because it has adverse effects on people’s health due to indoor air pollution. To children, even the smallest exposure to lead is a major concern to their slowly developing bodies.

Organophosphate Pesticides

This chemical is a composition of the pesticides we use at our homes to get rid of insects. This indoor pollutant leads to the damage of the nervous system.

Indoor exposure to this pollutants is common since it can be ingested or inhaled from the surfaces, the quantities available indoors might not be big enough to give adverse effects immediately, but it does in the long run upon inhalation of these chemicals.

Volatile Organic Compounds

These are present in the majority of consumer products and decomposing materials. The major categories are benzene, naphthalene, and formaldehyde. Volatile organic compounds will react with the ozone layer to form harmful indoor gasses. Similarly, when some holes hold items are dispose of, their decaying leads to the emission of yet another gas that pollutes indoor air. The levels of volatile organic compounds in a home may serve as an indicator of the quality of the air that is contained indoors.
