No fish in the control died during test period (mortality should be ≤ 10% or 1 fish if seven used). Oxygen concentration did not drop below actual minimum 90% (should be >60%). Analytical dose verification confirmed the exposure to the test item.
The acute toxicity of the test item to juvenile fish of the species rainbow trout (Oncorhynchus mykiss) was determined under GLP in a 96 hour static test according to the OECD TG 203, adopted 2019. The validity criteria were met. On the basis of the pre-test results, a limit test was performed in accordance with the test guideline to demonstrate that the test item has no toxic effect on the test organisms up to and including the nominal concentration of 100 mg/L during an exposure period of 96 hours. A control was tested in parallel. Seven fish were used in the treatment group and the control. The fish were observed for visible abnormalities and mortality at approximately 2 and 5 hours after the start of exposure and twice every 24 hours period thereafter.
No remarkable observations were made concerning the appearance of the test medium. Test medium was clear throughout the entire test duration. The measured concentration of the test item in the test medium was 106 and 105 % of the nominal value at the start and the end of the test, respectively. The test item showed no toxicity under the conditions of the test.
96-hour LC50 >100 mg/L, rainbow trout
The acute toxicity of the substance to the freshwater fish rainbow trout (Oncorhynchus mykiss) was studied under GLP to OECD TG 203 over a period of 96 hours. The substance did not exhibit any adverse effects on the test organisms and the 96-hour LC50 value was greater than 100 mg/L.
