Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The results show that under valid static test conditions, the 96 h-LC50 of Sal 90 to fish (Rare minnow, Gobiocypris rarus) is greater than the nominal concentration of the 110 mg/L WAF (measured concentration 0.417 mg/L), while the maximum concentration causing no mortality (96 h-LCo) was equal to the nominal concentration of 110 mg/L W AF (measured concentration 0.417 mg/L). i.e.:
96 h-LCso > 110 mg/L WAF (measured concentration 0.417 mg/L);
96 h-LCo = 110 mg/L WAF (measured concentration 0.417 mg/L).
Executive summary:

The results show that under valid static test conditions, the 96 h-LC50 of Sal 90 to fish (Rare minnow, Gobiocypris rarus) is greater than the nominal concentration of the 110 mg/L WAF (measured concentration 0.417 mg/L), while the maximum concentration causing no mortality (96 h-LCo) was equal to the nominal concentration of 110 mg/L W AF (measured concentration 0.417 mg/L). i.e.:

96 h-LCso > 110 mg/L WAF (measured concentration 0.417 mg/L);

96 h-LCo = 110 mg/L WAF (measured concentration 0.417 mg/L).
