Hydrogen Sulphide (H2S)

Hydrogen sulphide is a colourless gas with a rotten egg odour. Its presence in natural gas makes the gas "sour." Some sources include:

  • natural gas processing plants
  • petroleum refining
  • animal feedlots.
Alberta's one-hour guideline for hydrogen sulphide is 0.010 parts per million (ppm).
