Toxicity of thiocyanate to fish, plankton, worm, and aquatic ecosystem
Bioassays were conducted to examine the toxicity of thiocyanate to fish, plankton, and worms under different climatic conditions. Tilapia Oreochromis mossambicus, the crustacean Moina micrura, and the oligochaete worm Branchiura sowerbyi were used. The temperature conditions were 20, 25, ad 28 degre...

Summary: | Bioassays were conducted to examine the toxicity of thiocyanate to fish, plankton, and worms under different climatic conditions. Tilapia Oreochromis mossambicus, the crustacean Moina micrura, and the oligochaete worm Branchiura sowerbyi were used. The temperature conditions were 20, 25, ad 28 degree C. Results showed that fish were most susceptible and worms were least susceptible to thiocyanate, but all three species were more susceptible at higher water temperatures. At higher thiocyanate doses, fish exhibited convulsions, gasping, and flaring of the operculae. Dissolved oxygen, primary productivity, and plankton populations were reduced severely at thiocyanate concentrations ranging 0.77 1.02 mg/l. |
