Additional information
Hazard to aquatic organisms was assessed based on the following key studies for each trophic level tested, and consisted of the following:
Fish:
96h LC50 (Pimephales promelas) = 255.3 mg/L; ASTM E729-80; Markarian (1983)
Invertebrates:
21d NOEC (Daphnia magna) = 10 mg/L; OECD 211; Wetton & McKenzie (2004)
48h EC50 (Daphnia magna) = 113.6 mg/L; ASTM E729-80; Markarian & Karp (1983)
48h EC50 (Acartia tonsa) = 60 mg/L; PARCOM Ring Test Proposal; Weideborg (1996)
Algae:
72h EC50 (Skeletonema costatum) = 175 mg/L; 72h NOEC = 10 mg/L; ISO 10253; Weidebor (1996)
72h EC50 (Desmodus subspicatus) = >97 mg/L; 72g NOEC = 97 mg/L; EU Method C.3; Anon. (1990)
Microorganisms:
3h NOEC (ASRIT) = 100 mg/L; OECD 209; Chemex (2001)
Conclusion on classification
The substance does not meet any of the criteria for environmental classification in accordance with Regulation 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
