Hydrogen toxic effects

Caution Because tellurium compounds have toxic effects similar to those of arsenic compounds care should be taken not to bring tellurium tetrachloride and its reaction products into contact with the skin. Avoid breathing fumes and dust of tellurium compounds. In addition, hydrogen chloride is evolved in Step A, and pyrophoric Raney nickel is used in Step B. Therefore all manipulations described in this procedure must be carried out in an efficient fume hood. 

There appears to be some evidence that ethanol can increase the effects of hydrogen sulfide. In 6 cases, less hydrogen sulfide was needed for toxic effects to be observed when workers had consumed alcohol 16-24 hours earlier (Poda 1966).

A number of compounds act in synergy with cyanide to produce toxic effects. In smoke, hydrogen cyanide may interact with other toxicants (Birky and Clarke 1981). High blood cyanide levels were found in fire victims however, the carboxyhemoglobin levels were also high. Thus, it is difficult to assess the... 

On exposure to blue-green light, isomerisation of one or both double bonds takes place, forming trans,cis-bilirubin and trans,trans-bilirubin. In these compounds, hydrogen bonding to water molecules takes place, so that the molecule becomes increasingly water-soluble and can be excreted, relieving the baby of its toxic effect. 

The toxic effects of mustard gas are primarily related to its alkylating ability. In an aqueous environment, mustard gas rearranges and loses one or two molecules of hydrogen chloride then, mustard gas, minus its chlorides, becomes firmly attached through one or both of its P-carbon atoms to tissue components, altering their functional and physio-chemical properties. Cytotoxic effects have...
