A general belief is that pollution is confined to outdoors only and that our indoors areas are safe from any pollutions. Contrary to this belief, it has been established that indoor air pollution is as much of an issue as that of outdoor pollution. Indoor air pollution basically refers to the presence of harmful biological, physical and chemical agents being present in our homes, offices and other public places. There are various sources that contribute to indoor pollution at our houses and offices. Biological toxins such as pollen and mold, smoke arising out of tobacco or any other toxic materials, pesticides and other household chemicals, building materials such as asbestos, lead and gases are the main causes for indoor air pollution.
Solvents and chemicals used for perfumes, body sprays, furniture polish, moth repellents, and insecticides are a few other indoor air pollutants. These materials affect various parts of our body such as our nose, throat and eyes by creating headache, nausea and other complications. Smoking contributes the highest levels of indoor pollution in most houses where one or more members indulge in regular smoking. This not only affects the person who smokes, but also the other family members are affected as they too inhale the harmful substances released by the tobacco smoke.
In developed countries, houses are constructed airtight to prevent outdoor pollution from entering into the house. However, due to inadequate air circulation and lack of proper ventilation, the air inside the homes still becomes polluted. Smoking, pets and usage of household chemicals increase indoor pollution. In rural areas, especially in developing countries, people still rely on traditional fuels such as firewood, cow dung and charcoal for cooking. These fuels generate huge amounts of smoke and other polluting agents; becoming the main cause for indoor pollution in rural areas. The main victims of indoor pollution in rural areas are women and children as they spend most of their time inside their houses.
According to a WHO report, indoor pollution is the most serious environmental crisis in the developing countries. The most dangerous pollutants released from bio-fuels are carbon monoxide, particulates, formaldehyde and polycyclic organic agents. The problem is that most of the rural areas do not have proper monitoring mechanisms to check indoor pollution. This can be eradicated only if it can be properly controlled and houses are well ventilated.
