Document Summary
8. 4% of the total burden of disease in low and middle-income countries is the result of 3 environmental conditions: unsafe water, hygiene and excreta disposal; outdoor air pollution and indoor air pollution. Environment: external physical, chemical and microbiological exposures and processes that impinge upon individuals and groups and are beyond the immediate control of individuals. Use of solid fuel (fossil fuel, coal, biomass fuels of cow dung, wood, logging wastes and crop waste) for cooking and heating. These fuels do not completely combust instead they leave behind breathable particles of a variety of gases and chemical products. Kerosene or gas is safe (poor people can"t afford to switch) Improved disposal of human waste is associated with reductions in diarrheal disease, intestinal parasites and trachoma. Indoor air pollution: mostly affect women and young children. Falls disproportionately on children who suffer such a large share of the global burden of disease from diarrhea. Diarrhea is also associated from poor personal hygiene.
