Applicant's summary and conclusion

Conclusions:
Based on the nominal concentrations the mean lethal concentration LC50(96 h) is >4600 mg/L. The no observed effect concentration NOEC(96 h) is 100 mg/L.
Based on the analytically detected concentrations the mean lethal concentration LC50(96 h) is > 640 mg/L. The no observed effect concentration NOEC(96 h) is 100.5 mg/L.
