unusual facts about Hydrogen sulfide



Anaerobic oxidation of methane

In benthic marine areas with strong methane releases from fossil reservoirs (e.g. at cold seeps, mud volcanoes or gas hydrate deposits) AOM can be so high that chemosynthetic organisms like filamentous sulfur bacteria (see Beggiatoa) or animals (clams, tube worms) with symbiont sulfide-oxidizing bacteria can thrive on the large amounts of hydrogen sulfide that are produced during AOM.

Donald Canfield

The Canfield ocean, a sulfidic partially oxic ocean existing between the Archean and Ediacaran periods, takes its name from his seminal paper.

Environmental issues in the Niger Delta

Gas flares have potentially harmful effects on the health and livelihood of the communities in their vicinity, as they release a variety of poisonous chemicals including nitrogen dioxides, sulphur dioxide, volatile organic compounds like benzene, toluene, xylene and hydrogen sulfide, as well as carcinogens like benzapyrene and dioxins.

Pitting Resistance Equivalent Number

Furthermore a PREN-value ≥ 40 for duplex steels is called for in the DIN EN ISO 15156 as well as the American NACE - a standard for use in hydrogen sulfide environments known in the oil and gas extraction industries.

Stephen Alvarez

In Mexico he photographed a poisonous hydrogen sulfide cave, Cueva de Villa Luz, where scientists study clues to the origins of life.
