Short-term toxicity to aquatic invertebrates

Description of key information
Based on read across some components of alkenes C11/13/14 are acutely toxic to aquatic invertebrates at concentrations below their limit of solubility.
Key value for chemical safety assessment
Additional information
Data were read across from dodec-1-ene. The toxicity of dodec-1-ene toDaphnia magnawas investigated in an OECD 202 test (Brixham Environmental Laboratories, 2010). Due to the low solubility of the test substance the study used a solvent carrier. The test substance was mixed with the solvent before being added to the dilution water. It was then stirred for 48 hours under sealed conditions to maximise the exposure concentrations. The test was carried out with sealed test vessels and the solutions were renewed daily to minimise the loss of the test substance.
At the lower loading rates (0.032 - 0.18 mg/l) the measured concentrations were below the limit of detection (0.01 mg/l) throughout the test. No effects were seen at these loading rates. A 55% effect was observed at 0.32 mg/l, the next highest loading rate. Exposure concentrations at this loading rate were detectable throughout the exposure period except during the final 24 hour period when concentrations fell from 0.058 to <0.01 mg/l following the final exchange. The EC50 therefore lies between loading rates of 0.18 and 0.32 mg/l and the analytical monitoring indicates that the exposure concentrations at these loading rates was <0.063 mg/l.
Data were also read across from tetradecene. Christensen (1996) tested the toxicity of tetradecene to Mysidopsis bahia in a guideline study. Due to the low solubility of the test substance used a Suspended Particulate Phase (SPP) approach was used. A single SPP solution formed from 500ml test substance in 4500ml dilution water was diluted to form the various test concentrations. Increased mortality was not seen at the highest tested concentration of 1000000mg/l SPP.
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.
