Meta Description: Approximately half the world’s population and up to 90% of rural households in developing countries rely on biomass fuels in the form of wood, coal, animal dung, and crop residues. As many deleterious substances are produced from food materials via cooking, various types of pollutants are also emitted due to the incomplete combustion of these fuels.
These pollutants include Particulate matter (PM) and the associated components (metals, Polycyclic aromatic hydrocarbons (PAH), etc) as well as numerous gaseous constituents (e.g., carbon monoxide, formaldehyde, nitrogen dioxide, volatile organic compounds). As such, the use of household biomass fuel can act as the source of Indoor air pollution (IAP) through which various forms of pollutants are released.
Exposure to IAP may be responsible for nearly 2 million excess deaths in developing countries and for some 4% of the global burden of disease. Children are particularly vulnerable to IAP because their metabolic pathways are underdeveloped and immature. It is thus imperative to acquire the basic knowledge concerning the diverse health risks associated with cooking emissions in relation with the use of coal and biomass fuels.
