Applicant's summary and conclusion

Conclusions:
The mortality of Oryzias latipes was 0, 0 and 100% after 96 -hour exposure to Sodium surfacitin at 1, 10 and 100 mg/L, respectively. The 50%-lethal concentrateion (LC50) range of Sodium surfactin was 10 -100 mg/L after 24 -, 48 -, 72- and 96-hour exposure.
Executive summary:

The mortality of Oryzias latipes was 0, 0 and 100% after 96 -hour exposure to Sodium surfacitin at 1, 10 and 100 mg/L, respectively. The 50%-lethal concentrateion (LC50) range of Sodium surfactin was 10 -100 mg/L after 24 -, 48 -, 72- and 96-hour exposure.
