Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and alga). The lowest acute is a 96-h LC50 of 11.8 mg/L in fish (Pimephales promelas). Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified as acute aquatic toxic according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).
Long-term aquatic toxicity data are available only from a study with algae Pseudokirchnerialla subcapitata in which a NOErC value of 5.95 mg/L (> 1 mg/L) was derived. Furthermore, the substance is classified as readily biodegradable. The log Kow is 2.1 (no experimentally determined BCF value is available). According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) ii, as well as the acute value for Daphnia and fish according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:
- The substance has a chronic toxicity value of > 1 mg/L. Based on this information, the substance does not need to be classified according to Table 4.1.0, (b) ii.
- The lowest acute toxicity value falls between > 1 but ≤ 10 mg/L. The substance is rapidly degradable. Based on this information, the substance does not need to be classified according to Table 4.1.0, (b) iii.
Overall, it can be concluded that the substance does not need to be classified according to EU CLP (EC 1272/2008 and its amendments).
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.
