“…Most published methods for determination of cyanide exposure perform the analysis on blood samples. For humans, determination of cyanide exposure has been attempted from blood (34,37,45,49,51,55,59,82,95,, urine (49-53, 64, 142), saliva (54,55,64,70), expired air (56)(57)(58)(59)(60), and tissue (post-mortem) (51,129,140,143,144) samples. Blood may be the most versatile biological sample used to determine exposure to cyanide, because the analyses of cyanide, thiocyanate, ATCA, and cyanide-protein adducts can each be performed on blood samples.…”
