H2S occurs naturally in crude petroleum, natural gas, volcanic gases, hot springs, and can also result from bacterial breakdown of organic matter. Industrial sources of H2S include petroleum refineries, natural gas plants, petrochemical plants, coke oven plants, food processing plants, and tanneries.

Elemental Instruments, a division of Ohio Lumex, offers a range of hydrogen sulfide analyzers that provide online, real-time measurements to control the emissions, protect environment and plant equipment.

Hydrogen sulfide (H2S) is a flammable, toxic, colorless gas that is often characterized as having a ''rotten egg'' smell. People can typically smell hydrogen sulfide at low concentrations in air, ranging from 0.0005 to 0.3 parts per million (ppm). Brief exposure to high levels of H2S can cause death, while lower, long-term exposure can lead to eye irritation, fatigue, and headaches.
