Problems in aquatic ecosystems caused by anions-cyanide

Aquatic plants are unaffected by cyanide at concentrations that are lethal to most species of freshwater fish and invertebrates. Under aerobic conditions, microbial activity can degrade cyanide to ammonia, which then oxidizes to nitrate. This process has been shown effective with cyanide concentrations of up to 200 parts per million.
