H2S gas produced from the decomposition of waste with bad odor lead to subjective complaint forscavenger at Benowo, Surabaya the landfill when they are exposed too long. Preliminary survey on subjectivecomplaint showed that there were three people experienced dizziness, 4 people experience eye irritation, 2 withcoughing, and 6 people did not experience any complaint.
