E-mail: mila_dirga@yahoo.com,julisoemirat@gniail.cotn Abstract Co~nplaintsfrom irritation of skin, cough, bad odor, and nausea was suffered by 100% of a village (KS) inhabitant, in Western Java. The location of KS being upon a hill, just across factories along the coast. The KS inhabitants blarne the factories for emitting gaseous pollutants, which cause them to suffer the mentioned symptoms. This study was done to investigate the possible relationship of health effects and air pollutants and to estimate the health risk. It designed as a retrospective case-control study and the health risk measured as odd ratio. The results then verified by the air quality study. KS inhabitants who were exposed more likely suffireil :he h e ~ l i l tffFz;s i as co~lrpareilto K C wlro were 11v1exposed, bul the concentrations ofpollutants were all below the standard except PM. In conclusion, the health risk from air pollutants in KS as the exposed area were much higher than the unexposed area, and the study presents premature ex'idence of health effect and air pollutant exposure association particularly PM. Introduction Complaints from irritation of skin and eyes. cough, bad odor and nausea were experienced by nearly 100% of KS inhabitants, located in Gerem District, Cilegon. Cilegon has been the home of heavy industry and a ma-jor coasta: industrial city in Banten province, lndonesia. The location of KS being upon hill, just across the industrial site for emitting gaseous pollutants. The inhabitants blamed these industries which caused them to suffered the mentioned symptoms. S.

Industries are major source of air pollution, which emit air pollutants, namely nitrogen oxides (Nod, volatile organic contpounds (VOCs), carbon monoxide (CO), carbon dioxide (COI), sulfur dioxide (S01) and particulate matter (PM). Exposure to ambient air pollutants influenced by industrial emissions has been linked to anumber of different hea!th outcomcs, starting from modest transient changes in the respiratory tract and impaired pulmonary function and continuing to restricted activitylreduced perfomlance, .. . visits to the hospital emergency department, admission to hospital and death [I]. Therefore, an objective study was needed to evaluate whether thcrc was a correlation between air pollutants exposure in the ambient air and the health effects. This paper present fi~rtherinvestigation of the health risk from air pollution exposure in KS. In t h i s study, a retrospective epidemiological study was clearly the first step in assessing the adverse health effects that could result from contact with environmental pollutants. I n addition, local air quality study was conducted to verify the results of the epidemiological study, since the health outcome is directly related to air concentration of the pollutants [2]. Monitoring of ambient air quality could provide data to ascertainair pollu60n concentrations in a specific area [j].However, air quality monitoring system in this area of study was no! available because of economically unfeasibility. Hcnce, air quality model was used in this study to estimate ambient concentrations as a crucial stcp in assessing pvtential risk to human health due to inhalation of ambient air [3]. Methods Area of Study - KS is a village in Gerem District, Cilegon. Cilegon is located in the western of Java island, Bantcn province, Indonesia (Fig. 1). According to the geographical location, Cilegnn have tropical climate, consist of the rainy season (January to May) with average rainfall is 50-150 mm and dry season (June to December) with average rainfall is 100-150 mm. Daily temperature is about 3 1.4"C and 254°C at night time, and average wind speed range to 3.7 d s e c until 4.8 d s c c [4].

Ranten Povince Sitc Map Epidemiologic Study The epidemiologic study was carried out to estimate the health risk from air pollutants in the area of study. This study was conducted after the symptoms receded, the peop!e at the time of study were healthy and no longer suffer any symptoms. Hence, the epidemiologic study design was a retrospective case-control study. Basicly, there were two comparable yroops :vhich consist oC an cxposeu group (defined as the cases) and unexposed group (defined as the controls). The two groups should similar particularly in social-economic level, so that the differences found between the hvo groups only in t e n s of exposure to environmental pollutants. The data were obtained from questionnaire and interviewed face to face, as well as obser\.ation of exposure status in subject without assignment and without following individual subjects for change in disease status. The collected data be composed of variables related to socioecono~nicand health status. The obtained data then would be sun>niarized in contingency matrix 2-by-2 as illustrated in Table 1 151.

Dirsawati et al. ~~- ~- ~- ~ -- ~- In this study, the cases were KS inhabitants viho expmed by air pollution and experienced the heathsyrnptoms. The selected control were KC village inhabitants, which similar in social-economic level and assumed not exposed by the ambient air w h i c h influenced by the industrial emissions since it was located just behind the hill where KS was. Sampling was based on purposive sampling. The subjects consist of 72 cases and 62 controls, determined by Slovin Equation as follows [6,7]: Where: N = Population number n = Samples number = E n o r tolerance = 1 -confidence interval (desired) e Risk is classically defined as the probability that a specific outcome or diseasewill develop within a stated period of time [R]. I n this study, the. health risk was quantified by Odds Ratio (OR), which estimated indirectly by comparing disease iiequency for the exposed population and unexposed population and calcrllated as the number of exposed individuals divided by the number of unexposed individuals in each group [9]. OR defined how much more likely it is that someone who is expnsed !o the fictc: under study will develop the outcome as compared to someone who is not exposed [lo]. Based on Table 1, mathematical equation for calculating O R as follows [I 01: . . ~ ajb OR=-=c/d ~. u.d b.c (2) Air Quality Study The Gaussian Dispersion hlodel was applied to pred~ctair concentration at receptors.

The model calculates thc concetitration X at any receptor location (X, Y, Z) from a continous source with an effective stack height [I?]. ~ Health risk lion1 air pollutants. an epidemic in Western Java Indonesia -~ ~ ~ . 205 ~ ~ The input for the Gaussian Dispersion Model consists of emission information, meteorological data and receptor information. The predicted pollutants consists of HC, NO,, CO, SO2 and PM. Emission information were obtained directly from single stack measurements and the results were evaluated against the emission standard (Tablc 2). Other parameter sening for the madel were exhaust gas velocity (4.7 mlsec), exhaust gas temperature (217°C). inner stack diameter (1.20 m), stack height (40 m) and pressure (75.979 mmHg). Table 2.

It shows the direction from which the wind was blowing, the length of varioas segclents of :kc spokes show the percent oitime the wind was of the designated speed [12]. A receptor grid for off-site receptor was set - u p using Cartesian grid with a 500 m grid sp~cingout to distance of 2.0 km from the center of the industrial site. The distance from the stacks to the KS was & 1,5 krn and to the KC was +_ 2,0 km .

Tlre predicted air concentrations were expressed as 115'rn3. The result was illustrated as a contour map of concentration distribution ofpollutant released from a point source called isopletlrs [12]. The uncertainty of the modeling result was assessed by direct comparison with the measurements results. The ineasured pollutants comprise HC, NO,, CO, Sg2aiid PM as well. M. Dirgawati et al.

But the concentrations o f all gaseous pollutants were below ambient air standard and in cont~ast the concentrations o f PM were exceeded the ambient airstandard. There was likely that the health effect suffered by inhabitants in the exposed area were caused by irritants gas which absorbed in PM. I Conclusion The health risk from air pollutants in the exposed area were much higher than the unexposed area. The environmental epidemiologic study presents premature evidence that there was association between health effect and air pollutant exposure particularly PM. Further research would be n ~ e d e d to investigate the atmospheric PM in the area o f study. It was recommended that the factories on one hand, should reduce their emissions. On the other hand: an appropriate continuous ambient air pollution m ~ n i t o r i n gdevice should bc installed to be able to evaluate better the zmbient air and provide some warning of impending health problem. Further environmental epiden~iologicresearch would be needed to accurately measure the health risk from air pollutants. References 1. W I 0 . (2006).
