Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
No mortality of fish was observed in limit test. Therefore, exact values of LC50 and LC100 could not be calculated and the values of LC are given in the form of a range. The NOEC values are identified by direct observation.
The nominal concentration of the test substance was used for all evaluations and results.

LC50 - 24h,48, 72h ,96h > 100 mg/L
LC100 - 24h,48, 72h ,96h > 100 mg/L
NOEC - 24h,48, 72h ,96h = 100 mg/L
