Abstrak: As an industrial area, Tangerang district has high upper respiratory tract infection (URI or URTI) and tuberculosis cases. Sulfur dioxide (SO2) is one of industrial waste gases causing those diseases, the concentration tends to increase along dry season. By employing a model, a research related to the air pollutant exposure and public health can be more practical and efficient. This study aims to analyze the exposure of SO2 to the residents around Tangerang district in dry season including distribution of SO2 concentration emitted using Chimere model, the mass of pollutants inhaled by individual, Inhalation Transfer Factor (ITF), and Population Inhalation Transfer Factor (PITF). Results of Chimere model showed that SO2 concentration along dry season reached 0.2-2.7 μg m-3 and the mass of pollutants inhaled by individual ranging from 0.16–21 μg hr-1. ITF and PITF estimations for PT X in unstable atmospheric condition (A) were 2.7x10-8 and 9x10-5 respectively, whereas 1.2x10-9 and 4x10-5 in stable atmospheric condition (F) respectively. ITF and PITF estimations for PT Y in unstable atmospheric condition (A) were 4x10-8 and 1.3x10-4, whereas in stable atmospheric condition (F) were 1.9x10-8 and 6.5x10-4 respectively. Those PITF values were categorized as urban ambient air ranging from ~10-6- ~10-3.

Judul: Potensi Deposisi Asam di Wilayah Industri Kabupaten Tangerang dan Sekitarnya Menggunakan Chimere Model
Abstrak: Increased industrial activity and transportation become the sources of pollutanand potentially degrade ambient air quality. One of the effect of air quality degradation is acid rain phenomenon. Purpose of this study is to determine the concentration of air pollutants (SO2 and NO2)and its potential for acid deposition. Tangerang is one of the cities that has the potential to decrease air quality due to the many industrial areas as well as the density of the motor vehicle. Potential acid deposition in this region were analyzed using Chimere program model. The results showed concentrations of SO2 maximum is27.50 ugm-3and NO2 gases maximum is 60ugm-3. This value is far below the Indonesian National Air Quality Standard of 60 ugm-3for SO2 and 100 ugm-3for NO2 in 365ugm-3. The average of NO2dry deposition fluxes in the five observation days is 5.3525x1015 molecule cm-2 s-1 and SO2 is 3.7573 x1015 molecule cm-2 s-1. While the average value of NO2wet deposition fluxes is 0 molecule cm-2 s-1 and SO2 is 4.8553x1010moleculecm-2 s-1. Estimated pH of rain on average in the study area is4.6, that indicate acid rain.
