Description of key information
n/i-C13 -C15 –aldehydes are acutely toxic to fish. The LC50 (96 hrs) was >0.4 and <0.9 mg/L.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 0.8 mg/L
Additional information
The acute toxicity of n/i-C13 -C15 –aldehydes was tested compliant with GLP in a valid OECD TG 203 (1992) assay using zebra fish (Brachydanio rerio), using Tween 80 as emusifier. The analytically verified concentrations were 0, 0.4, 0.9, and 1.6 mg/L. A solvent control with emulsifier Tween 80 was included.
After 96 hours mortality was 0, 71, and 100% in groups exposed to the low (0.4 mg/L mean measured), intermediate (0.9 mg/L mean measured), and high (1.6 mg/L mean measured) test concentration. The LC50(96 hrs)was >0.4 mg/L and <0.9 mg/L in this study (Hoechst, 1994). For the purpose of assessing the PNEC, the 96 -h LC50 was recalculated by forming the geometric mean of the 96 -h LC0 and LC100. This resulted in a 96 -h LC50 of 0.8 mg/L.
This study is considered to be valid and useful for assessment.
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.
