Quantification of hydrogen cyanide in fire effluent

Fire deaths in the Glasgow area: III. The role of hydrogen cyanide.

Cyanide generation during preservation of chlorinated wastewater effluent samples for total cyanide analysis.

Dechlorinating agents and pH adjustment are often used to preserve wastewater samples for cyanide analysis. The effects of four approved preservation protocols on the results of the total cyanide analysis of effluents from four water reclamation plants were examined. The results differed widely, and a clear pattern emerged. Immediate analysis without pH adjustment generally gave total cyanide c...

Metabolism of hydrogen cyanide by higher plants.

A survey has been made of the occurrence and distribution of three enzymes which metabolize cyanide in a variety of higher plants including both cyanogenic and non-cyanogenic species. The enzymes investigated were beta-cyanoalanine synthase, rhodanese and formamide hydrolyase. beta-Cyanoalanine synthase was found to be present in every higher plant tested whereas rhodanese was found to occur fa...
