Good Water (4456) Hydrogen Sulfide Test Kit
Hydrogen Sulfide: Resulting from the anaerobic decomposition of organic matter, hydrogen sulfide is present in many water supplies
Sewage and industrial wastes are other sources of sulfide pollution
Sulfide reacts with colorimetric reagents to form a blue color, which is measured with a color disc.
Highly toxic, this compound has a characteristic rotten egg odor, which can be detected long before harmful concentrations are reached
