An analytical control of the nominal concentration of the test material in water should have been performed. However, the mortality to fish is caused in the range of the nominal concentration of the test material of 100 mg/L up to 1800 mg/L. In this range of nominal concentration the active ingredient should be very well soluble in water (120 g/L). Therefore, it can be concluded that the nominal concentraion is causing the mortality.
An acute toxicity study on rainbow trout was carried out in year 1990 according to OECD Guideline 203 and GLP.
The procedure used in this investigation corresponded to a flow-through test with continuous aeration. The 96 hour LC50 was
determined to be 1340 mg/L.
