Abstract

Measurements of PM10 and water-soluble ions were carried out on indoor and outdoor PM10 (particles < 10 μm in aerodynamic diameter) aerosols sampled at selected primary schools of Kuala Lumpur (S1) and Putrajaya (S2), respectively. Samples were collected using a low volume sampler on Teflon filters. The water-soluble ions chloride (Cl-), nitrate (NO3 -), sulfate (SO4 2-), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+) and ammonium (NH4 +) was analyzed using ion chromatography. The results showed that the indoor PM10 mass concentrations in S1 and S2 were 96.6 and 69.5 μg/m3, while the outdoor PM10 mass concentrations were 80.1 and 85.2 μg/m 3, respectively. This indicated that NO3 - were the most dominant ions, followed by SO4 2-, Ca 2+, K+ and Na+, while Cl-, Mg 2+ and Na+ were present at low concentrations. Pearson's correlation test applied to all the data showed high correlation between SO 4 2- and NO3 -, indicating a common anthropogenic origin. In addition, the correlations between Na+ and Ca2+ indicated crustal origins that significantly contributed to human exposure.
