- mortality (fish)
Any other information on results incl. tables
- Sublethal observations / clinical signs:
Test conditions met all validity criteria, given by the mentioned guidelines.
There was less than 5% mortality within the 48-hour settling-in period and <= 10% mortality in the control(s). Dissolved oxygen saturation was greater or equal to 60% throughout the test and pH variation was <= 1.0 units.
The limit test showed that at 10.0 mg test item / L.
The test item did not cause any mortality to Rainbow trout (Oncorhynchus mykiss). The 96h-LC50 is greater than 10.0 mg / L.
There were no mortalities or sublethal effects noted at this concentration after 96 hours. The 96 h NOEC is >= 10.0 mg / L.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Executive summary:
The limit test showed that at 10.0 mg test item / L did not cause any mortality to Rainbow trout (Oncorhynchus mykiss).
