This study aimed to investigate the composition of dust particles in the atmosphere, the chemical nature of the dust samples from EMC station (Environmental Monitoring center) in Serpong. Indonesia And studied the concentration And elemental composition of the air cleaner include PM2.5, PMcoase, PM10 and carbon black (Black Carbon: BC) sampling during October - December 2556 using techniques GENT Stack Filter and identify the composition and concentration of trace elements. by X-Ray Fluorescence techniques, black carbon (BC) measured with Smoke Stain Reflectometer. The technique of reflection. And analyzing the composition and concentration of elements by ED-XRF Epsilon 5 techniques particles caused by X - ray (PIXE) Al, Si, S, K, Ca, Ti, Cr, Fe, Mn, Na, Ni. , Zn, and Pb, the results showed that the highest concentrations of PM10 and PM 2.5 34.34 μg / m³ and 14.60 μg / m³, respectively, an average of PM 2.5 and PM 10 was 34.34 μg / m³ and 14.60 μg / m³, respectively. The average concentrations of BC is between 1.56-3.62 μg / m³ and found heavy metals with the highest concentration of lead. (Pb), which have a concentration of 0.67μg / m³.
