SUMMARY OF AVAILABLE DATA (key values)
Acute toxicity to aquatic organisms (pelagic):
- Fish (Brachydanio rerio): 96h-LC50 = 2.66 mg active content/L (as a LC50 value expressed in solid content was not reported, the LC50 value expressed in active content was used as a worst-case for the assessment);
- Crustaceans (Acartia tonsa): 48h-EC50 = 6.62 mg solid content/L;
- Algae (Skeletonema costatum): 72h-EC50 = 2.69 mg solid content/L.
Chronic toxicity to aquatic organisms (pelagic):
- Fish (Pimephales promelas): 32d-EC10 = 0.075 mg solid content/L;
- Crustaceans (Daphnia magna): 21d-NOEC = 1.39 mg solid content/L;
- Algae (Skeletonema costatum): 72h-NOEC = 0.9 mg solid content/L;
- Microorganisms: 3h-EC10 > 1328 mg solid content/L.
Toxicity to sediment organisms:
- Crustaceans (Corophium volutator): 10d-EC50 = 8302 mg solid content/kg sediment dw.
Toxicity to terrestrial organisms:
No data.
All effective concentration are expressed in solid content and are relevant for the REACh-registered substance (= active content + minor constituents + impurities).
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.
