Key study: Test method OECD 203. GLP study. The 96 hours LC50 value for OS-2200 in rainbow trout was > 100 mg/L and the NOAEL was 100mg/L based on the nominal exposure concentration.
Key study: An acute fish test was performed according to EU Method C1
and OECD Guideline 203 under GLP conditions. A limit test was performed
on Rainbow trout (Oncorhynchus mykiss) at 100 mg/L of test item. 10 fish
per vessel were exposed to 0 (control) and 100 mg/L test item under
semi-static conditions for 96 hours. No mortalities or significant
treatment-related effects on the fish were noted. Therefore, the 96
hour-LC50 was determined to be >100 mg/L and the NOEL was 100 mg/L based
on the nominal concentration.
