Introduction: Purabaya Terminal or commonly referred to as Bungurasih Terminal is a type of A passenger terminal and the main terminal of Surabaya City, which is located outside the southern and western borders of Surabaya City, precisely in the administrative area of Bungurasih Village, Sidoarjo Regency. Purabaya Terminal is a type A terminal with an increased risk of activity vehicles that cause air pollution, resulting in hydrogen sulfide (H2S) and ammonia (NH3) gas which pose a risk to the health of the surrounding community when exposed to vehicle pollution. This study aims to analyze environmental health risk analysis of hydrogen sulfide (H2S) and ammonia (NH3) from vehicle fumes around Purabaya Terminal with a radius of 250 and 500 meters in 2022.
Methods: This research is a type of descriptive research using quantitative analysis methods. The sample in this study was 50 people with a sampling technique using purposive sampling within a radius of 250 and 500 meters.
Results: The highest level of H2S exposure was at point 3, which was 0.004 mg/m3. Meanwhile, the highest level of NH3 exposure was at point 2, which was 0.029 mg/m3.
Conclusion: Based on the research that has been done, it can be concluded that the levels of H2S and NH3 at a radius of 500 meters are smaller than those of a radius of 250 meters.
