Test solutions
- Details on test solutions:
- Identity and concentration of auxiliary solvent for dispersal: Preliminary solution were prepared in dimethylformamide at a
concentration of 100mg/10ml solvent. An aliquot of this
solution was then dispersed in dechlorinated tap water to
give this 1mg/l test concentration.

- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 96 h
Test conditions
- Hardness:
- 100 mg CaCO3/L

Any other information on results incl. tables
- Sublethal observations / clinical signs:
The 96-Hour LCso for the test material to rainbow trout (Oncorhynchus mykiss), based on
nominal test concentrations was greater than 1.0 mg/I and correspondingly the No
Observed Effect Concentration was equal to 1.0 mg/I.
The test concentration of 1.0 mg/I was the highest attainable test concentration due to the
limited solubility of the test material in water and auxiliary solvent, and having due regard
for the amount of auxiliary solvent permitted in the test under the OECD Guidelines.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The acute toxicity of the test material to the freshwater fish rainbow trout (Oncorhynchus mykiss) has been investigated and gave a 96-Hour LC50 of greater than 1.0 mg/I. Correspondingly the No Observed Effect Concentration was equal to 1.0 mg/I.
- Executive summary:
The acute toxicity of the test material to the freshwater fish rainbow trout (Oncorhynchus mykiss) has been investigated and gave a 96-Hour LC50 of greater than 1.0 mg/I. Correspondingly the No Observed Effect Concentration was equal to 1.0 mg/I.
