WebMRL for hydrogen sulfide is 20 ppb. Per the study evaluating nasal passage damage that established this measure, there were no adverse health effects observed at 460 ppb. No health effects have been found in humans exposed to typical environmental background concentrations of hydrogen sulfide (0.11–0.33 ppb). WebThe gas sensing performance of the cF 3 poPcCo/rGO hybrid gas sensors towards ppb hydrogen sulfide (H 2 S) was measured at room temperature. The results show that the 4-cF 3 poPcCo/rGO sensor has better sensitivity, selectivity and reproducibility than the 3-cF 3 poPcCo/rGO sensor, as well as a perfect linear response to the concentration of H 2 S. costa titch ursache

WebHydrogen sulfide is a colorless gas with a rotten-egg odor. Some people can smell hydrogen sulfide at very low levels, as low as 0.5 parts per billion (ppb) in air. Most hydrogen sulfide in the air comes from natural sources. It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such ...
