H2S is the most dangerous. In humans, one or two breaths of air, with as little as 600 parts permillion (ppm) H2S, can cause a person to lose consciousness. Deaths are not uncommon when people enter poorly ventilated spaces such as deep wells, underground tanks or sewer systems. Hydrogen sulfide is a central participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth. [82] In the absence of oxygen , sulfur-reducing and sulfate-reducing bacteria derive energy from oxidizing hydrogen or organic molecules by reducing elemental sulfur or sulfate to hydrogen sulfide.
