Preliminary study on the oxygen consumption rate and
asphyxiant point of Wuchang bream in Poyang Lake.
Cyanide and hydrogen sulfide are chemical
asphyxiants that disrupt cellular oxidative phosphorylation.
An extensive, entirely predictable inventory of weapons and munitions can be reconstructed from isolated references to 'obus', 'fusants', 'marmites', 'grenades', 'mitrailleuses', 'pieces contre avions', 'revolver', 'canons', 'gaz
asphyxiant', 'fils de fer'.
"The gas is an
asphyxiant , and can kill if it is breathed in when there is a fairly high concentration of it around."
Ms Julie Mason, spokeswoman for the plant's owners and operators British Energy, said the alarm was raised when higher than normal levels of carbon dioxide, which is an
asphyxiant, were detected by safety devices in the basement.
An odorless, colorless chemical
asphyxiant, it is both toxic and flammable.
Carbon dioxide is an
asphyxiant gas and not classified as toxic or harmful in accordance with the Globally Harmonized System of Classification and Labelling of Chemicals Standards of the United Nations Economic Commission for Europe within the meaning of the Organisation for Economic Co-operation and Development (OECD) Guidelines for the Testing of Chemicals.
Light hydrocarbon gases: a narcotic,
asphyxiant, or flammable hazard?
Under normal conditions at ambient temperature, C[O.sub.2] is a colorless, odorless gas and a simple
asphyxiant that displaces oxygen when inhaled.
Carbon monoxide (CO), a colorless and odorless gas, is classified as a pulmonary
asphyxiant. High level exposures can cause toxic effects or death in humans and animals (1); CO poisoning reportedly is responsible for as many as 4,000 deaths per year in the United States (2).
