Health Risk Assessment of Indoor Air Quality in Developing Countries

The health effects of many pollutants such as particulate matter, carbon monoxide, oxides of sulfur and nitrogen, and polycyclic aromatic hydrocarbons Reparable particulate matter is now regarded as the single best indicator pollutant for review the overall health-damaging potential of most types of combustion, including that of biomass. Rural societies use fuel wood and biomass fuel for cooking and heating, which is not only expensive but also produces smokes that influences their health and pollute indoor environment. Usually, cow dung is generally put in the courtyard of rural households, which harbors insects, flies and produce vulgar smell that affects the health of the dwellers. A preliminary review of the literature reflects that there exist a substantial amount of literature and existing data in the form of published report on indoor air pollution. The overall research design is exploratory the review is related to the indoor air pollutant status among the developing countries. The main diseases according to above literature were asthma, respiratory tract infections, chronic pulmonary diseases, lungs cancer etc. the studies were conducted in the developing countries such as Pakistan, India, Bangladesh, Uganda, Africa, Sri Lank, China, Ethiopia, Nepal.. So it concluded that developing countries had major problem of health hazards because use of biomass fuel for the purposes of cooking.
