H2S Vial Bacteriological kit use for checking microbiological quality of water.Scientists from the University of Exeter discovered that cell exposure to small amounts of hydrogen sulfide gas can prevent mitochondrial damage. When the cell is stressed with disease, enzymes are drawn into the cell to produce small amounts of hydrogen sulfide. This study could have further implications on preventing strokes, heart disease and arthritis. many metal ions react with hydrogen sulfide to give the corresponding metal sulfides. This conversion is widely exploited.
