Conclusion on classification

In order to determine the classification for hazardous properties related to the aquatic environment, the criteria of the Regulation (EC) No 1272/2008 (CLP) version 2019 in Annex I were accurately followed.

Short-term (acute) aquatic hazard:

For classification, acute toxicity data are available for fish, aquatic invertebrates (Daphnia) and algae. The lowest LC50 or EC50 values observed for the different trophic levels in water are:

Fish: LC50 (96h) = >36.7 mg/L

Daphnia: LC50 (48h) = 56 mg/L

Freshwater algae: EC50 (72h, growth rate) = 83 mg/L

The criteria in Table 4.1.0 (a) of Annex I of the CLP Regulation were applied.

The lowest LC50 or EC50 value was observed for fish, which are hence the most sensitive species. According to Table 4.1.0 (a) the substance should not be classified for acute aquatic hazard, as the lowest EC50 value, is larger than the cut-off for classification of 1 mg/L.

Long-term (chronic) aquatic hazard:

No long-term testing was performed on fish or Daphnia. Therefore, as indicated in Figure 4.1.1, the most stringent classification needs to be taken of:

(1) Table 4.1.0 (b) (i):

Substance not readily biodegradable

Algae (72h): EC10 = 20 mg/L

Conclusion: Not classified since the measured EC10 value is far above the cut-off value of 1 mg/L.

(2) Table 4.1.0 (b) (iii)

Substance not readily biodegradable

BCF ≤ 500

Fish: LC50 (96h) = >36.7 mg/L

Daphnia: LC50 (48h) = 56 mg/L

Conclusion: Since the substance is not readily biodegradable and the lowest measured EC 50 is 36.7 mg/L (in range of > 10 and ≤ 100 mg/L), the substance is to be classified as chronic, category 3.

Conclusion on long-term aquatic hazard: The substance is to be classified as chronic 3.
