Conclusion on classification
Short-term toxicity results for Daphnia and algae are available for the substance. The 48-h EC50 value for Daphnia is 5.1 mg/L and the 48-h ErC50 value for algae is 2.0 mg/L. 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).
Chronic toxicity data are available only for algae. The 48-h ErC10 value is 0.38 mg/L. 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 according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:
- The substance is readily biodegradable and has a chronic toxicity value of 0.1-1 mg/L. Based on this information, the substance needs to be classified for chronic aquatic toxicity as Category 3: H412 according to Table 4.1.0, (b) ii.
- The substance is readily biodegradable, has a log Kow value of >4 and an acute toxicity value of > 1 but ≤ 10 mg/L. Based on this information, the substance has to be classified for chronic aquatic toxicity as Category 2: H411 according to Table 4.1.0, (b) iii.
Overall, it can be concluded that the substance does not need to be classified for acute, but is has to be classified for chronic aquatic toxicity as Category 2: H411 according to EU CLP (EC 1272/2008 and its amendments).
In addition, as the 48h-EC50 for Daphnia magna and the 48-h ErC50 for algae is between 1 -10mg/L, the substance needs to be classified as Acute Cat. 2 (H401) according to GHS.
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).
