Respiratory symptoms, lung function and particulate matter pollution in residential indoor environment in Ile-Ife, Nigeria.

This article is from Nigerian Medical Journal : Journal of the Nigeria Medical Association , volume 55 . Abstract Introduction:: Particulate air pollution is associated with increased incidence of respiratory symptoms and decreased pulmonary, function but the relative impact of pollution from different domestic energy sources is not well-known or studied. Aim:: The study was aimed at assessing the association between particulate concentrations, respiratory symptoms and lung function. Materials and Methods:: It was a cross-sectional study comprised of randomly selected residents of three communities. These communities were selected according to the predominant type of fuel used for household cooking which were: firewood, kerosene and liquefied petroleum gas (LPG). Assessment of the indoor PM10 levels was done by filtration using the Gent stacked filter unit sampler for collection of atmospheric aerosol in two size fractions (PM2.5 and PM10). The Medical Research Council (MRC) questionnaire was administered followed by spirometry test. Results:: The mean PM10 concentration in participants using LPG, kerosene and firewood was 80.8 ± 9.52 μg/m3, 236.9 ± 26.5 μg/m3 and 269 ±93.7 μg/m3,
