Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The following results were determined for the test item 'Reaction mass of biphenyl-2-yl diphenyl phosphate and triphenyl phosphate and bis(biphenyl-2-yl) phenyl phosphate and tris 2-biphenylyl phosphate' (species: Daphnia magna):

24h-NOEC = 13 mg/L measured conc. (100 mg/L nominal conc.)
48h-NOEC = 13 mg/L measured conc. (100 mg/L nominal conc.)
24h-EC50i > 13 mg/L measured conc. (100 mg/L nominal conc.)
48h-EC50i > 13 mg/L measured conc. (100 mg/L nominal conc.)

The test substance showed no toxic effects up to its limit of solubility in water.
