Hydrogen sulfide

Hydrogen sulfide 1 Structures, 2 Names and Identifiers, 3 Chemical and Physical Properties, Hydrogen sulfide appears as a colorless gas having a strong odor of rotten eggs, 4 Spectral Information, 6 Chemical Vendors, 7 Drug and Medication Information, Sulfur 5% to 10% in a petrolatum base is

Hydrogen Sulfide – Overview

Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes, Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed spaces, such as manholes, sewers, and underground telephone vaults, Its presence makes work in confined spaces potentially very dangerous, The health effects of hydrogen sulfide depend on how much H2S

Hydrogen Sulfide

Hydrogen sulfide H₂S is a colorless gas with a strong odor of rotten eggs, Exposure to hydrogen sulfide may cause irritation to the eyes and respiratory system, It can also cause apnea, coma, convulsions; dizziness, headache, weakness, irritability, insomnia; stomach upset, and if liquid: frostbite, Workers may be harmed from exposure to hydrogen sulfide, The level of exposure depends upon

Hydrogen Sulfide – an overview

Hydrogen sulfide is produced by these bacteria and is released to the protected environment, where it reacts with the dissolved iron from the corrosion process to form iron sulfide Martin et al,, 2005, So, it is sometimes necessary to remove hydrogen sulfide from a drilling mud, Techniques using iron compounds that form sparingly soluble sulfides have been developed, e,g,, with iron II oxalate

Hydrogen Sulphide – an overview

Hydrogen sulfide concentrations in ambient air range from 0,11–0,33 ppb and in urban areas are generally <1 ppb, although much higher concentrations often exceeding 90 ppb have been detected in communities located near natural sources or industries releasing hydrogen sulfide, In undisturbed anoxic sediment, hydrogen sulfide levels may be as high as 100 ppb and in disturbed sediments may

Hydrogen Sulfide

Hydrogen sulfide is produced naturally by biological degradation of sulfur-containing products eg, fish, sewage, and manure and produced as a byproduct in many industrial processes ie, paper mills, heavy-water production, petroleum refineries, tanneries, mines, carbon disulfide production, and hot asphalt fumes, It can often be found naturally in sulfur hot springs, volcanoes, and
