About half of the world’s population, mostly in rural areas of Asia, Sub-Saharan Africa and Latin America, still rely on unprocessed biomass as their primary source of domestic energy. Nearly 2 billion kg of biomass such as wood, animal dung and agricultural wastes are burned everyday in developing countries, and it accounts for more than 80% of domestic energy in India. A survey conducted jointly by National Council of Applied Economic Research and World Bank in 1996 has reported that about 578 million tons of biomass is used annually in India as a source of domestic energy of which wood constitutes 52%, animal dung 21% and agricultural refuse 20%. The annual consumption of wood is 302.1 million tons, dung cake 120.6 million tons and crop residues 115 million tons. In general, rural domestic sector in India uses 1.2-2.1 kg of biomass/capita/day [1].
In West Bengal, a state of eastern India, 45.6 million tons of biomass is used annually for cooking and room heating. Firewood remains the mainstay of biomass fuel in the state with an annual usage of 23.3 million tons/year, followed by agricultural wastes (11.9 million tons/ year) and dung cakes (10.3 million tons/year). Biomass fuel use as a source of domestic energy is even more in Bangladesh and Nepal where 88% and 80% of the population respectively are dependent on biomass fuels for household cooking. The percentage of users is marginally lower in Pakistan (72%) and Sri Lanka (67%) [2].
Poverty is the major cause of biomass fuel use. People living in rural areas of developing countries are generally poor who can ill afford cleaner fuel such as liquefied petroleum gas (LPG) with their modest income. Instead, they rely on biomass which are cheaper (or free of cost) and readily available. No wonder, there are only a handful of LPG users in rural India, and in most of the cases the LPG owners also use biomass (mixed user) to reduce fuel cost.
Biomass fuels are at the high end of the fuel ladder in terms of pollution emissions, and at the low end in terms of combustion efficiency. Biomass burning during daily household cooking usually in un-vented kitchen emits very high levels of smoke that contains a wide range of potentially hazardous pollutants. They include particulates; carbon monoxide (CO); oxides of nitrogen and sulfur; polycyclic aromatic hydrocarbons including carcinogens such as benzo(a)pyrene (PAHs), volatile organic compounds (VOCs) including benzene, a human leukemogen and trace metals including Fe, Cu, Ni, Cr and Pb [3-5].
Airborne particles with a diameter of less than 10 μm (PM10) are hazardous because they can be inhaled deep inside the lungs and serve as a vehicle for toxic matters that usually adsorb onto their surface. Burning biomass emits more PM10 than LPG or electricity. For example, particle concentrations in the kitchen vary from 200 to 5,000 μg/m3 of air during cooking with biomass fuels [6,7] in contrast to 200-380 μg/m3 during cooking with LPG or electricity [8]. Moreover, fine (aerodynamic diameter <2.5 μm, PM2.5) and ultrafine particles (diameter <0.1 μm), constitute a bulk of the biomass smoke [9] and most of the mass is due to the presence of fine particles i.e. PM2.5 which are more harmful for human health than PM10 [10]. Biomass smoke is considered even more harmful than diesel, because it contains 10-times more mass concentration of respirable particles having diameter of 0.5- 0.8 μm compared to diesel [11].
In rural India, the biomass-using ovens are not vented outside, kitchens are often poorly ventilated, and half of the poor, rural families do not have separate kitchen. These factors contribute significantly to high particulate level in cooking areas. A typical biomass-using Indian kitchen, the 24-hr average concentration of PM10 ranged from 500- 2000 μg/m3 during cooking [12] and the level of IAP depends on the type of fuel, stove and housing [6,7]. This implies that women who used to cook with biomass are inhaling approximately about 23,000 μg (23.0 mg) of PM10 per day, quite in contrast to a normal baseline of 1,728 μg (1.7 mg) per day. This is highly significant from health perspective because for every 20 μg/m3 of PM10 rise in ambient air, daily mortality increases by 1%.
Indoor air pollution (IAP) also varies with type of biomass used for cooking or room heating. Compared with wood, combustion of dung cakes and briquette emitted significantly higher carbon monoxide and particulate matter. Exposure to this high pollution load from burning biomass fuels is regarded as one of the most important environmental and public health problems in developing countries especially in women who cook with these fuels and in young children who attend to the fires or stay close to their mothers during cooking. It has been estimated that IAP from biomass use in developing countries is responsible for 4-5 percent of global burden of disease for both deaths and DALYs (disability adjusted lost life years) from acute respiratory infections (ARI), chronic obstructive pulmonary disease (COPD), tuberculosis, asthma, genetic damage [13,14] lung cancer [15], ischemic heart disease and blindness. India registers over 600,000 premature deaths per year due to biomass fuel combustion. Smoke inhalation has been reported to be an important cause of acute lung injury with high mortality rate. Increasing evidence suggests that screening and early detection may improve the outcome of lung cancer.
