The chronic effects of cyanide on oxidative stress indices

This study was conducted in order to elucidate the effects of cyanide (CN−) as sodium cyanide on oxidative parameters in the tissues of birds (Gallus domesticus L.) exposed to CN− directly by gavage and indirectly through their feed. Lipid peroxidation (LPO) level and activities of alase () and superoxide dismutase (SOD) were determined in the kidney, liver, heart, and brain of the

Can You Use Sodium Cyanide When Mining Manganese

Cyanide an overview ScienceDirect Topics. The reaction can be alyzed by iron, copper or manganese. Ore processing in gold and silver mining operations uses dilute solutions of sodium cyanide (100 to 500 ppm), Death usually occurs within an hour, but may take as long as 3 hours if Small amounts of cyanide can be exhaled as HCN (hydrogen cyanide).
