Abstract


Quantitative information on mass and elemental concentrations and sources of indoor aerosols, examining the relationship between indoor and outdoor particulate matter (PM) in Ibadan City were provided. Mass concentrations of PM2.5 and PM2.5-10 and elemental composition were determined using standard weight and Instrumental Neutron Activation Analysis (k0 - INAA) method. Nine elements viz: As, Br, Cu, K, La, Na, Sb, Sm and Zn were detected in the fractionated PM samples. The mean mass concentrations of PM loadings obtained for firewood, kerosene and cooking gas environments were 50.0, 22.2 and 22.7 ug/m3 for PM2.5 and 20.1, 24.3 and 9.0 ug/m3 for PM2.5-10 respectively. It was observed that the mean elemental concentration of potassium (K) in the fine fraction is approximately twice the values in the coarse fractions for kerosene residence and four times firewood residence. The high concentrations of Potassium in both fractions indicate that firewood is predominantly present in the study area. This has detrimental implications on the health of the populace.

Keywords: Particulate matter (PM), Indoor air pollution, Cooking fuel.
