Cyanide spills in general were tracked using data from National Analysis of Trends in Emergencies Systems (NATES) for 1974 to 1995 (Environment Canada, 2000). This is shown in Eig. 39.3 and includes spills of cyanide leachates, sodium cyanide, cyanide not otherwise specified (nos), and cyanide/copper tailings. As can be seen in Fig. 39.4, cyanide nos is the largest of the spills and may contain any cations with cyanide or the cyanide ion itself. 

Statistical spill data are extremely useful for setting priorities and identifying project needs for spill prevention and preparedness. This was recognized in 1972, and a database was developed to consolidate all Canadian spill data. This database is known as NATES, short for National Analysis of Trends in Emergencies System. The NATES database now contains data on over 150,000 spill events. About 60% of these spill events are related to oil and petroleum products. About 20% involve wastes and aggregate materials. Only about 10% involve the spillage of pure chemicals.
