In the environment, thiocyanate is typically found in water, soil, and various organisms. Its presence can be attributed to multiple sources, including the combustion of fossil fuels, agricultural runoff, and industrial effluents. One of the most common ways thiocyanate enters the ecosystem is through the breakdown of cyanogenic compounds, which are prevalent in certain plants. For example, crops like cassava and lima beans can release thiocyanate during digestion or processing. This transition from harmless plant components to potential contaminants highlights the need for monitoring thiocyanate levels in agricultural and aquatic systems.
