  Case Report: Fatality from potassium gold cyanide poisoning

  2019726 · Potassium gold cyanide (KAuCN 2 ) is a readily available occupational compound used in metal plating and gold mining. KAuCN 2 is an uncommon exposure that can result in multiorgan dysfunction and death. The toxic effects of KAuCN 2 may result from both cyanide and gold toxicity. Management of both gold and cyanide toxicity should be …
