Indoor air pollution is a major environmental health problem affecting both developed as well as developing countries. It bursts from the sources of dust, gases and smoke, and is propagated mainly by human activities. People’s exposure to indoor air pollution is determined by the concentrations of pollutants in the internal environment and, most importantly, by the time individuals spend in polluted habitat. Internal air quality of the residential environment is affected by many factors and with an effort to conserve energy, modern building plan has favoured airtight structures with less ventilation. Outdoor pollution is more hazardous when it becomes indoor air pollution. According to the recent data over 2 million deaths occur every year because of indoor air pollution. Toxic products, improper ventilation, high temperature and humidity are some of the factors responsible for indoor air pollution in our internal environment.
Sources of Indoor Pollutants Are –
Asbestos: is the main cause of indoor air pollution. Asbestos can be present in different types of materials that are generally used in industries and constructing buildings. They are commonly present in coatings, paints, building materials, ceiling and floor tiles. It has been banned in the US as it is responsible for causing serious health issues such as lung cancer, asbestosis, mesothelioma, and other types of cancers.
Formaldehyde: is another common indoor air pollutant which is present in paints, sealants, and wood floors. It is responsible for the irritation of throat, eyes, and nose and various types of cancer.
Radon: is a gas that naturally occurs in soil and various kinds of bedrocks that can get inside the houses by diffusing through soil. It causes lung cancer.
Tobacco Smoke: causes severe respiratory problems like respiratory irritation, pneumonia, bronchitis, emphysema, heart disease, as well as lung cancer.
Microbes: Microorganisms like bacteria, moulds and viruses can come in indoor areas and responsible for various types of allergies, flu, infections and asthma. They grow well in damp areas as well as in animal dander and make sick.
Objects: such as wood stoves, space heaters, and fireplaces cause respiratory infections, damage and irritation to the lungs.
Chemicals: used in pest control, varnishes, paints, and certain cleaning products emit pollution inside the home and responsible for poor indoor air quality causes bad odours, headache, irritation in eyes, nose, throat, loss of coordination, liver, brain, and kidney damage and cancer.
Pets and pests: Pets, pests, dust mites, cockroaches and mice are the various sources of allergens. These allergens can lead to diseases of the airways, rhinitis, and asthma. But, people who are allergic should avoid exposure to substances to which they are allergic.
How to Improve Indoor Air quality- Quit smoking, stop using woodstoves as well as certain types of space heaters, use of vacuum cleaner with brushes, keep your shoes out of the living area.
