University of Minnesota Center for Drug Design and Minneapolis VA Medical Center researchers have discovered a new fast-acting antidote to cyanide poisoning. This antidote works in less than three minutes meeting the United States Department of Defense "three minute solution" standard. The antidote is also unique because it can be taken orally (current antidotes must be given intravenously) and may be administered up to an hour prior to cyanide exposure. This is the best antidote known to date because of it’s quick reaction time to cyanide, a poison that acts equally as fast. This antidote was tested and approved in 2007.

Cyanides refers to the family of salts that, such as sodium cyanide and potassium cyanide. The organic salt of cyanides are called nitriles. HCN is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals In 1782, A Swedish chemist, Scheele, heated the pigment with diluted sulfuric acid and he got a combustible gas that formed acid when dissolved in water, which he called "Berlin Blue Acid", what is now hydrogen cyanide. The name "cyanide" was used from Greek word of "Kyanos“, which means blue.

AURUL, an Australian/Romanian Joint Venture was created to extract ferrous metals from waste piles of rock or area mines using cyanide. On January 30 th, 2000 at approximately 10 p.m. almost 100,000 cubic meters of high- concentrated cyanide water was dumped into the Zazar and Lapos waterways, which was connected to the Szamos River. As a result, the river suffered an extremely large loss of fish stock, and the polluted water also posed a serious threat to human health for everyone living in the area. Microscopic examination of water samples taken from the Szamos showed that 90-95% of zooplanktons died.
