Peatland fires occur regularly in Central Kalimantan. Smoke particles generated by peatland fires are in the PM2.5 size range. Inorganic component such as metals and other elements in PM2.5 emitted from peatland fires contribute to air pollution. This study was conducted in Palangka Raya to measure PM2.5 concentration at two types of sampling locations namely Source and Receptor (Kalampangan; Jekan Raya), identify concentration and contribution of 20 trace elements (Na, Mg, Al, Si, S, Cl, Cd, K, Ca Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Pb) to PM2.5, identify potential source with enrichment factor approach, and analyze health risk assessment. According to this study average of PM2.5 concentration at Source (2,986±1,472 ?g/Nm³), Kalampangan (168±91 ?g/Nm³), and Jekan Raya (272±83 ?g/Nm³). Zn, S, Pb, Na, Al, and K were found as six dominant elements in PM2.5 from source and receptor sampling. Average contribution of trace elements to PM2.5 at Source (0.21±0.03%), Kalampangan (0.28±0.06%), and Jekan Raya (0.38±0.09%). S, Cl, Cd, Co, Cu, Zn, As, and Pb were categorized as enriched elements. Peatland fire emissions were indicated as major source of these elements in Receptor. HI?1 for both of Receptor sampling means that exposure to metals which cause non carcinogenic effect (Cd, Cr, Mn, Co, Ni, and As) cannot cause non cancer health effects. ELCR both of Receptor sampling are in the range of 1,0×10-6 (1 in 1.000.000) to 1,0×10-4 (1 in 10.000) means that exposure to metals which cause carcinogenic effect (Cr, Cd, Co, Ni, As, and Pb) cannot cause cancer health effects.
