Population growth, changes in consumption patternsandlifestyles of peoplehave increased theamount of waste, types, anddiversitycharacteristics of waste. The increasing volumeof wasterequiriesmanagement in order to minimize negative impacts not only to health but also to the environment.The study aims to investigate the health risk of the scavengers in the final waste disposal site at Tamangapa of Manggala District of Makassar City. The study was carried out in Tamangapa final waste disposal site with observational design in the form of environmental risk analysis approach. It also used 14 environmental samples existing in seven measuring points with three sampling times: in the morning, at noon, and in the afternoon and it involves 60 human samples. The data were analysed with ARKL method and Excel Tabulation.The study indicates that the average concentration of sulfur dioxide (SO2) in ambient air in the site is 25.53 μg/Nm3 in the morning, 31.16 μg/ Nm3 at noon, and 24.34 μg/Nm3 in the afternoon. Meanwhile, the average of concentrations of Nitrogen Dioxide (NO2) in the ambient air in the final waste disposal site is 37.10 μg/Nm3 in the morning, 47.79 μg/Nm3 at noon, and 34, 44 μg/Nm3 in the afternoon. In the mean time, the amount of risk (RQ) of Nitrogen Dioxide is 0.0864 mg/kg/day in the morning, 0.1147 mg/kg/day at noon, and 0.0850 mg/kg/day in the afternoon
