I am a marine science student doing a study on the treatment of cyanide in the marine environment. Would like to know what a good treatment for a major spill would be, how long the area would remain toxic and if possible the effects of the treatment on life (if any left in the area). The type of spill I am researching is cyanide from mining practices. Any help on these question or any information regarding cyanide would be greatly appreciated. I have refered to the internet and scientific journals with no real luck. Thanks for the time.
