Hydrogen sulfide (H 2 S) is a flammable, colorless gas that smells like rotten eggs. People usually can smell hydrogen sulfide at low concentrations in air, ranging from 0.0005 to 0.3 parts hydrogen sulfide per million parts of air (ppm). At high concentrations, a person might lose their ability to smell it.

Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes. Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed spaces, such as manholes, sewers, and underground telephone vaults. Its presence makes work in confined spaces potentially very dangerous.

Aug 10, 2022· Principle. An iron compound and a sulfur compound are included in the test medium to test for the production of hydrogen sulfide gas. Hydrogen sulfide is produced if the sulfur compound is reduced by the bacterial strain. This test thus determines whether the microbe reduces sulfur-containing compounds to sulfides during the process of metabolism.

Sep 10, 2022· What is Hydrogen Sulfide (H2S) Test? This test determines whether sulfur-containing chemicals are converted to sulphides during the microbe's metabolic activity. When sulphide is generated, it reacts with iron compounds to form FeS, a black precipitate. Multiple iron-containing media permit the detection of hydrogen sulphide generation. …
