Applicant's summary and conclusion

Conclusions:
For the short-term toxicity to fish a LC50 value of 79.17 mg/L could be calculated by ECOSAR. This value is in line with the information in the Annex III Inventory (ECHA list). Here it is mentioned, that the Danish QSAR database contains information indicating that the substance has a 96h LC50 to fish of 79.07 mg/L.
