＜Report by Rinawati＞
Destination and period: Jakarta, Indonesia, September 26th- October 10th, 2010
Purpose : to collect samples for sources identification of sedimentary and atmospheric PAHs in Jakarta , Indonesia
We collected surface river sediment samples using Ekman Dredge from several rivers that flow through Jakarta. Almost all of the sampling location mainly in northern of Jakarta were polluted rivers with characteristic dirty water, black color, a lot of floating garbage and odor. Jakarta has only one sewage treatment plant that means limited area was covered. Most residents discharge their domestic waste directly to the river or canal. The pollutant not only come from domestic waste but also from industrial area. This makes Jakarta Bay has function as receptor of domestic waste, industrial effluents, urban runoff, port activities and spillage may cause heavy pollution in this area. We also collected potential source material of PAHs such as street dust, tire, soot, and engine oil. Air samples were collected using High Volume Air Sampler (HVAS) from 5 locations where 3 locations for representative of heavily traffic road, 1 location for representative of industrial area, and 1 location for representative of residential area. Due to the poor public service transportation people still prefer to use their private car facilitating their transport. And there is no massive public transport in city. This fact implies Jakarta traffic congestion in main road of Jakarta especially in morning and late afternoon. We suffer traffic congestion every day during our sampling activities. The Overseas Field Training gave valuable experience and lesson to my future.
