Description of key information

Short-term toxicity to fish


A 96 h LC50 value of 5.3 mg/L was obtained with 95 % confidence limits of 4.6 - 6.1 mg/L.


 


Long-term toxicity to fish


According to Annex XI, paragraph 1.3 results obtained from valid QSAR models may be used instead of testing. A QSAR calculation is available for this endpoint showing that the substance is not chronic toxic to fish.


 


Short-term toxicity to aquatic invertebrates


Immobilisation of the daphnia was observed at nominal concentrations of 8 mg/L and greater. The 48 h EC50 was 8.3 mg/L.


 


Long-term toxicity to aquatic invertebrates


According to Annex XI, paragraph 1.3 results obtained from valid QSAR models may be used instead of testing. A QSAR calculation is available for this endpoint showing that the substance is not chronic toxic to daphnids.


 


Toxicity to aquatic algae and cyanobacteria


The 72 h ErC50 was determined to be 28 mg/L (95 % CL 25 to 32 mg/L); the NOEC and LOEC values based on the growth rate were determined to be 6.25 and 12.5 mg/L, respectively.


 


Toxicity to microorganisms


3-hour EC50 value of 100 to 1000 mg/L. The No Observed Effect Concentration (NOEC) after 3 hours of exposure was 100 mg/L.
