Abstract
Objectives: The development of broiler farm sector contributed to the air pollution in the form of odor due to the formation of hydrogen sulfide gas (H2S). Purpose: This study aims to analyze the level of risk of H2S exposure in the community near broiler farms PT.Ciomas Padang. Methods: The study used Environmental Health Risk Assesment (EHRA) method. Population consists of 160 people and 66 sample respondents with accidental sampling technique. Four point air samples taken on the settlement around broiler farms PT. Ciomas used gas sampler impinger. Results: Four point air samples were lower than odor threshold (0.02 ppm or 0,027 mg/m3) , H2S concentration was 0,015 mg/m3, 0,018 mg/m3, 0,022 mg/m3 and 0,023 mg/m3. The calculation of the largest realtime intake and lifetime intake found at location C. The average realtime intake value was 0,00135 mg/kg/day and intake lifetime was 0,00406 mg/kg/day. RQ value of realtime and lifetime, obtained all point of measurement has RQ>1 which means that H2S exposure is unsafe and risk management is necessary. Conclusion: The required risk management by limiting safe concentration and limiting the duration of exposure. Other efforts that can be done is by adding lime and prebiotic on chicken manure to reduce the release of H2S gas and cleaning the dirt under the cage once a week.
