Although free cyanide breaks down rapidly when exposed to sunlight, the less toxic products, such as cyanates and thiocyanates, may persist in the environment for many years.
All three sugary cassava landraces were found to have low free cyanide content (<3mg [kg.
Under normal physiological conditions, tissues of cyanophoric plants do not contain free cyanide; rather they contain cyanogenic glycosides, which upon hydrolysis by endogenous glycosidase yield free cyanide which could be toxic to the consumer [8, 9].

But sometimes free cyanide (cyanide ions and hydrogen cyanide) breaks down slowly--for example in water that is ice-covered and so protected from direct sun.
The influence of free cyanide is crucial as for each 1 gram per litre of free sodium cyanide increase reduces the efficiency of the solution by approximately 2%.
