Applicant's summary and conclusion
- Conclusions:
- The range of the EC50 (24h) was 370 -670 mg/l, the EC100(24h) 700 mg/l and the NOEC (24h) 300mg/l. Despite missing measurements of the test substance the test was accepted due to the extensive measurements of the test concentrations in the fish test (showing less than 5% loss over 96 h) and 24 h were accepted due to the high EC50 values. Two tests were performed. One with adjusment of pH value. This test was performed without adjustment of the pH. pH values range from 2.0 to 6.3 at the beginning of the test. At the end of the test the pH was 2.1 to 6.4. The highest tested concentration was 10000 mg/l. The adjusted pH was between 7.5 and 6.3 at the beginning of the test and between 2.1 and 6.4 at the end of the test (24h). The NOEC was 9000 mg/l. The LOEC was 10000 mg/l with 2.5 % inhibition. In the test the stability of the substance was not measured, but the test has been accepted, since in the fish test it was proven, that the substance is stable.
