Thiocyanate is noteworthy for its dual role as both a pollutant and a product of natural metabolic processes. In moderate concentrations, it poses minimal risk; however, elevated levels can lead to significant environmental and health ramifications. The compound is particularly concerning in aquatic systems, where it can exhibit toxicity to aquatic organisms. Studies show that high concentrations of thiocyanate can lead to bioaccumulation, affecting fish species and disrupting aquatic ecosystems. Investigating thiocyanate levels, therefore, becomes essential for maintaining ecological balance and ensuring the health of both freshwater and marine environments.
