All rights reserved.Atmospheric particulate concentrations for fine (particulate matter less than 2.5 micron) and coarse particles (particle with diameter 2.5-10 micron) were measured in 2 locations which are Tegalega and Dago Pakar Bandung. Tegalega represents an urban mixed site while Dago Pakar represents rural site. Samples on each location were collected over one or two days-time periods during dry and wet season using Dichotomous sampler and Low Volume Sampler (LVS). Meteorological conditions were also measured simultaneously in the sampling locations. Samples were further analyzed to determine concentrations of particulate mass, elements, sulfate, nitrate and ammonium. The results from this study show that the concentrations of the particulate mass were higher during the dry season than in the wet season for both locations, mixed and background sites. The average fine particles concentrations at mixed site were 37 and 49 μg/m3 for the wet and dry seasons respectively. The average coarse particles concentrations were 27 and 33 μg/m3 for wet and dry seasons respectively. The average mass concentrations of fine particles at the rural site were 30 and 45 μg/m3 for wet and dry seasons respectively, while for the coarse particles the concentrations were 13 for wet season and 17 μg/m3 in dry season. Concentration of Black Carbon, sulfate, nitrate, and ammonium mostly existed in the fine fraction while crustal elements dominated the coarse fraction. Black Carbon, Sulfate, nitrate and ammonium contributed about 55 % to the total mass of the fine particles at Mixed site (Tegalega) and about 52 % at rural site (Dago Pakar) in dry season. Fine particulate contribute about 57 % to the PM10 in Tegalega and about 73% in Dago Pakar (rural site). This indicates that fine particles may come from other places (transported) in the rural area.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]ammonium,Black carbon,Coarse particles,Fine particles,PM10,PM2.5,sulfate,Total suspended particles[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]ammonium,Black Carbon (BC),coarse particle,elements,fine particle,nitrate,PM10,PM2.5,sulfate,total suspended particle (TSP)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research project was funded by Swedish International Development Cooperation Agency (SIDA) through Asian Regional Research Program on Environmental Technology coordinated by Asian Institute of Technology (AIT).
