About Hydrogen sulfide (30min)

Hydrogen sulfide is a flammable, colorless gas that smells like rotten eggs. People usually can smell hydrogen sulfide at low concentrations in air ranging from 0.5 to 300 parts per billion (ppb). Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. It can also result from bacterial breakdown of organic matter. Industrial sources of hydrogen sulfide include petroleum refineries, natural gas plants, petrochemical plants, coke oven plants, food processing plants, and tanneries.

The guideline for Hydrogen sulfide is 5ppb (30 min avg) for odour nuisance and 108ppb (24hr avg) for health and wellbeing.

Hydrogen sulfide (30min) is measured in parts per billion.
