Potassium Cyanide - an overview ScienceDirect Topics
No signs of cyanide poisoning were observed; the gold concentration in whole blood was reported as 6011 μg/L 13 h after the ingestion, and the 24-h urinary gold was 429 μg/L (Wu et al., 2001). Similarly, in case of suicide by ingestion of gold potassium cyanide (2 g gold), it was concluded that effects were due to gold rather than to cyanide ( Wright and Vesey, 1986 ).
