Abstract

The obtained spatial distributions of NO2 and SO2 show that the highest concentration appears near the high traffic main highway, and then higher concentrations in business center and industrial areas. The highest “oneday” NO2, appeared at a site near toll highway in central Jakarta, was 446.1μg/m3; 16 observation points including this site exceeded 92.5μg/m3, the Jakarta ambient air quality standard (Jakarta AAQS). On the other hand, “one day” SO2 concentrations were below the Jakarta AAQS 260μ/m3, though these at two sites were over the WHO AAQS 125μg/m3. Vertical profile, up to 110 m high, of air pollution was also studied using a high building in business center of Jakarta. The “one day” NO2 concentration were 119.8, 101.3, 87.6, and 100.4μg/m3 at 10, 30, 55, and 110 m high, respectively, and similarly those for SO2 were 7.3, 1.8, 6.5, and 16.2μg/m3. It is interesting that the SO2 increases with height, suggesting huge point sources of power plants located along the coast in the north-eastern part of Jakarta may be resulted in this profile under the sea breeze condition. At the symposium, the results will be discussed together with CTM calculation.
