Description of key information
Additional information
Short term toxicity to fish
The acute toxicity of the test substance to fish was assessed in two studies conducted on Pimephales promelas, which revealed LC50 values of 6.7 mg/L and 10.8 mg/L, respectively. For risk assessment and C+L a key value of 6.7 mg/L was used.
Toxicity to aquatic invertebrates
In the acute immobilisation test with Daphnia magna (STRAUS), the 48 h-EC50 value of the test substance was found to be 27.1 mg/L.
Toxicity to Algae
In a 72 hours toxicity test with the freshwater green algae Pseudokirchneriella subcapitata the EC50 value based on growth rate was determined to be 24.1 mg/L, the EC10 value was found to be 8.08 mg/L.
Toxicity to microorganisms
The toxicity control in the Ready biodegradability test showed no inhibition of the microbial activity at a substance concentration of 3.1 mg/L. According to the ECHA Guidance document R7b, no further test on the toxicity to microorganisms has to be conducted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
