Abstract

IntroductionUse of solid fuel for cooking is a major source of household air pollution in developing countries. Of the many pollutants emitted during solid fuel combustion, Particulate Matter (PM)is considered to be one of the most hazardous pollutants. We monitored PM fractions emitted during solid fuel and Liquefied Petroleum Gas(LPG) combustion in kitchens of Sri Lankan households.\n\nMethodsHouseholds of children in a longitudinal study in Ragama, Sri Lanka was the study population. At the age of 36 months of children, a sample of households were visited and different aerodynamic diameters of PM (PM1, PM2.5, PM10) were monitored during the main cooking session for 3 hours. Basic characteristics of kitchen (e.g., availability of chimney, functionality of chimney, etc.) were assessed by a questionnaire. Cooking energy, other sources of household air pollution, size of open spaces in the kitchen (e.g., windows), etc. were assessed at the time of PM monitoring.\n\nResultsQuestionnaire was administered for mothers in 426 households. Out of them, 245 (57.5%)and 116 (27.2%) households used LPG and wood as the primary cooking fuel respectively. During the cooking period, PM2.5 concentrations of households uses only wood fuel and co...Continue Reading
