Executive summary:

Study was performed according to OECD 203 guidance under GLP condition as a limit test. The total duration of the test was 96 hours. The test with Oncorhynchus mykiss (previous name: Salmo gairdneri) was performed under static condition. The measured test concertation over the first and last 24 hours of the exposure period were 101 - 89.4 mg/l and 105 - 104 mg/l respectively. During whole testing period no mortalities or sublethal effects were seen. The LC 50 based on fish mortality was established as more than 100mg/L. The NOEC (no observed effect concertation) was established as 100 mg/L (based on fish mortality).
