Additional information

Under the conditions of the test, the 96h-LC50of the test substance Thiazol Blue to Zebra fish (Brachydanio rerio) was greater than the saturation concentration (<0.005620mg/L, LOD) of the filtered test solution of nominalconcentration of 109 mg/L test substance solution. The 96h Lowest Observed Effect Concentration (LOEC) was greater than the saturation concentration of filtered test solution of nominal concentration of 109 mg/L test substancesolution. The 96h No Observed Effect Concentration (NOEC) was the saturation concentration of filtered test solution of nominal concentration of 109 mg/L test substance solution.
