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 2016 in Annex I were accurately followed.
Short-term (acute) aquatic hazard:
For classification, acute toxicity data are available for aquatic invertebrates (Daphnia) and algae:
Daphnia: EC50 (48h) = 0.114 mg/L
Algae: EC50 (72h, growth rate) = 0.0695 mg/L
The criteria in Table 4.1.0 (a) of Annex I of the CLP Regulation were applied.
The lowest EC50 value was observed for algae, which is hence the most sensitive species. According to Table 4.1.0 (a) the substance should be classified for acute aquatic hazard, as the lowest EC50 value, EC50 (72h) for algae = 0.0695 mg/L, is smaller than the cut-off for classification of 1 mg/L. Hence, the test item should be classified as Acute aquatic toxic 1.
Since the lowest EC50 value is below < 1 mg/L, the multiplying factor for acute toxicity was determined according to Table 4.1.3. The lowest EC50 is 0.0695 mg/L, which is > 0.01 and < 0.1 mg/L. Hence, a multiplying factor of 10 should be applied.
Long-term (chronic) aquatic hazard:
For chronic classification, there are only chronic data available for one trophic level, algae. As described in Figure 4.1.1 in the CLP regulation (EC No 1272/2008, version 2016), the most stringent outcome of classification according to Table 4.1.0 (b) (i) or (ii) and (iii) should be used.
Table 4.1.0 (b) (ii):
The substance is readily biodegradable, hence Table 4.1.0 (b) (ii) applies.
The EC10 (72h, growth rate) for algae was 0.0153 mg/L, which is less than 0.1 mg/L, the lowest cut-off for classification. Therefore, the substance should be classified as Chronic aquatic toxic, category 1.
Table 4.1.0 (b) (iii):
Classification based on available acute data available for 1 other trophic level (Daphnia) and environmental fate data:
Daphnia (48h) EC50 = 0.114 mg/L
Log Kow < -2
The substance is not readily biodegradable.
Based on the criteria Table 4.1.0 (b) (iii), the substance should be classified as Chronic aquatic toxic, category 1 since the EC50 for Daphnia is < 1 mg/L and the substance is not readily biodegradable.
Most stringent classification:
The conclusion of both assessments is that the substance should be classified for Chronic aquatic hazard, category 1.
Since the EC10 value is below < 0.1 mg/L, the multiplying factor for chronic toxicity was determined according to Table 4.1.3. The substance is not readily biodegradable and the lowest ErC10 is 0.0153 mg/L, which is > 0.01 and < 0.1 mg/L. Hence, a multiplying factor of 1 should be applied.
