Improving Indoor Air Quality for Poor Families : A Controlled Experiment in Bangladesh

摘要: The World Health Organization's 2004 Global and Regional Burden of Disease Report estimates that acute respiratory infections from indoor air pollution (pollution burning wood, animal dung, other bio-fuels) kill a million children annually in developing countries, inflicting particularly heavy toll on poor families South Asia Africa. This paper reports an experiment studied the use construction materials, space configurations, cooking locations, household ventilation practices (use doors windows) as potentially-important determinants pollution. Results controlled experiments Bangladesh are analyzed to test whether changes these can have significant effects Analysis data shows, for example, area diffuses into living spaces rapidly completely. Furthermore, it is important factor interaction between outdoor Among fuels, seasonal conditions seem affect relative severity biomass fuels. However, there no ambiguity about their collective impact. All far dirtier than clean analysis concludes if with fuels not possible, then building kitchen porous material providing proper areas will yield better health environment.
