【 摘 要 】

This paper presents a study on black carbon and ionic species concentrations in PM₁₀, sampled from the urban area of Makassar in the Province of South Sulawesi, Indonesia. The samples were collected on a weekly basis within a period of one year from February 2012 to January 2013. Results showed that the mean concentration of PM₁₀ black carbon was 2.01 ± 0.93 μg/m³, while ionic species concentrations were found in descending order; SO₄²⁻>NO₃⁻>Cl⁻>NH₄⁺, with mean concentrations of 1.44 ± 1.04 μg/m³, 1.11 ± 1.06 μg/m³, 0.87 ± 0.91 μg/m³, 0.49 ± 0.64 μg/m³, respectively. Black carbon concentration was higher during the dry months, which may be attributed to uncontrolled biomass burning during hot and dry weather conditions. Similarly, SO₄²⁻ and NH₄⁺ concentrations were higher during the dry month seasons. On the contrary, Cl⁻ concentration was higher during the wet months, influenced by the marine environment surrounding the area.
