Hydrogen cyanide (HCN) is volatile and highly toxic with acute and chronic effects on humans. Gaseous HCN enters the atmosphere from natural processes or industrial activities, which lead to human exposure. Effective intervention in cases of HCN inhalation requires an efficient diagnostic tool. The ...
The invention relates to a method for reducing a health risk to humans or livestock due to exposure of hydrogen cyanide (HCN) released from manure, comprising contacting the manure with an alkaline substance, which alkaline substance is used in an effective amount whereby – when mixed – the ...

Health HazardHydrogen cyanide is a dangerous acute poison by all toxic routes. Acute inhalation may cause death in seconds. Lethal effects due to inhalation of its vapor depend on its concentration in air and time of exposure. Inhalation of 270 ppm HCN in air can be fatal to humans instantly...
Cyanide, specifically hydrogen cyanide (HCN), and hydrogen sulfide (H2S) are two such blood gases of interest. Accurate assessments of the risks each pose are essential to capitalizing on their positive contributions to society and preventing further incidents. While these two compounds have been ...

Management is generally supportive, with promptendotracheal intubationandmechanical ventilationfor severe cases of intoxication. Oxygen enhances sulfide metabolism and benefits hypoxic tissue. Because the mechanism of toxicity is similar to that of cyanide, induction ofmethemoglobinemiawith infusion of 3%sodiu...
Flammability hazard characteristics:It is combustible in case of H hair pore agent; Case of cyanide release of toxic hydrogen cyanide gas; Thermal decomposition of toxic bromide gas. Storage and transportation characteristics:Low temperature and dry storage; and cyanide, Separate storage with cyanide, ...
This inhibition appears to be similar to that produced by carbon monoxide and cyanide (Szabó, 2007). H2S has also been identified as an energy source for many photo- and chemoautotrophic bacteria as well as animals such as the lugworm (Arenicola marina) (Goubern et al., 2007). H2S is ...
