Atmospheric Particulate Concentration Measured in an Urban Area Bandung

Atmospheric particulate concentration for total suspended particles (TSP) and for PM10 (particulate matter under 10 micron) was measured in Jalan Braga and ITB campus, Bandung. Six samples were collected over one- or two-day time periods using High Volume Sampler (HVS) for TSP and Low Volume Sampler (LVS) or Anderson Cascade Impactor for PM10. Samples were further analyzed to determine concentrations of metals, sulfate and nitrate. Concentration of NOx (NO and NO2) was also measured hourly and simultaneously during the sampling period. The results from this study show that the atmospheric particulate concentration in Jalan Braga for TSP ranged from 304.04 to 363.17, and for PM10 concentration ranged from 277.02 to 336.44 lg/m3. The lead concentrations were 1.42–2.37 lg/m3 in the TSP and 0.81–1.57 lg/m3 in the PM10. The nitrate concentrations were 5.89–6.51 lg/m3 and 2.27–3.45 lg/m3 for the TSP and PM10, respectively. The hourly NOx concentration varied between 0.14–0.35 ppm. The total elements (metals, sulfate and nitrate) found in the samples contribute from 20 to 25% of the total particulate concentration.
