Description of key information
Reliable acute studies based on international guidelines are available for the two aquatic trophic levels (aquatic invertebrate and algae) to assess the toxicity of the test substance OF14 AT.
No acute toxic effect of the test substance to the aquatic invertebrate Daphnia magna has been observed under the experimental conditions, with 0% of immobilization for all the test concentrations including the highest one (2343 mg/L). Thus, the 48h-EC50 has been determined to be higher than 2343 mg/L.
In the study assessing the acute toxicity of OF14 AT to the algae P. subcapitata, a concentration effect relationship has been observed and statistically analyzed to obtain effect concentrations. Thus, under the test conditions, the 72 h ErC50 was determined to be 245.9 mg/L and the 72 h ErC10 has been determined to be 33.1 mg/L.
Additional information
Justification for non classification as hazardous for environment:
Hydrophilic substance.
Acute aquatic toxicity data E(L)C50 > 100 mg/L.
No adequate chronic toxicity data available.
Log kow < 0.3, indicating low potential for bioaccumulation.
> 70% degradation in 28 days based on ThOD, indicating that it fulfils the criteria for rapid degradation.
Acute (short-term) aquatic hazard: not classified.
Long-term aquatic hazard: not classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
