Description of key information
Additional information
Short-term toxicity to fish:
Under the conditions of this acute fish toxicity study the observed endpoints for the effect of Incorez 397 were the followings: 96h LC50 value: 27.79 mg test item/L; 96h NOEC value: 6.25 mg test item/L and 96h LOEC value: 12.5 mg test item/L.
Short-term toxicity to aquatic invertebrates:
Under the conditions of this acute daphnia toxicity study the observed endpoints for the effect of Incorez 397 were the followings: 48h EC50 value: 68.79 mg test item/L; 48h NOEC value: 25 mg test item/L and 48h LOEC value: 50 mg test item/L. All reported biological results are related to the nominal concentrations.
Toxicity to aquatic algae and cyanobacteria:
Under the conditions of this acute algal growth inhibition test on Pseudokirchneriella subcapitata the observed endpoints for the effect of Incorez 397 based on the growth rate were the followings: 72h EC50 value: 14.80 mg test item/L; 48h NOEC value: 6.13 mg test item/L and 96h LOEC value: 12.22 mg test item/L. All calculations were based on the geometric mean of measured concentrations.
Toxicity to microorganisms:
The toxicity to microorganisms of Incorez 397 was tested according to OECD guideline 209 and EU method C.11. Activated sludge was exposed at nominal concentrations of 62.5, 125, 250, 500 and 1000 mg /L. The EC50 was determined to be 375.38 mg/L and the EC10 was 94.96 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
