Conclusion on classification

Short-term toxicity tests for fish, daphnia and algae are available for the substance. The lowest EC50 value was a 48h-EC50 of 1.5 mg/l for daphnia. 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 is also available for algae with a 72h-EC10 value of 6 mg/l and a fish NOEC of 0.17 mg/l (calculated using the critical body burden approach). According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for fish according to Table 4.1.0, (b) i, 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 not readily biodegradable and has a chronic toxicity value of > 0.1 but ≤ 1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 2 according to Table 4.1.0, (b) i.


- The substance is not readily biodegradable, has a log Kow value of 4.2 and an acute toxicity value of > 1 but ≤ 10 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 2 according to Table 4.1.0, (b) iii.


Overall, it can be concluded that the substance needs to be classified as Chronic Cat. 2 (H411) according to EU CLP (EC No. 1272/2008 and its amendments). In addition, as the 48h-EC50 for Daphnia magna, the 96h-LC50 for fish and the 72-h ErC50 for algae are between 1 -10 mg/L, the substance needs to be classified as Acute Cat. 2 (H401) according to GHS.
