Hazard for predators

Secondary poisoning

Hazard assessment conclusion:
no potential to cause toxic effects if accumulated (in higher organisms) via the food chain

Additional information

Although the substance is not readily biodegradable and has a partition coefficient of > 3, the substance is not classified as STOT category 1 or 2 or toxic for reproduction 1A, 1B or 2. Therefore it is viewed that the substance does not have the potential to cause toxic effects if it accumulates in higher organisms (as stated in ECHA TGD Guidance on information requirements and chemical safety assessment Part B: Hazard assessment section 7.2.7)

Conclusion on classification

The information concerning the aquatic toxicity of the substance are summarized hereafter:

Acute toxicity to fish: LC50_96hr = 8.8 mg/L

Acute toxicity to daphnia: EC50_48hr = 2.3 mg/L

Toxicity to algae ErC50_72 hr = 28 mg/L and ErC10_72hr = 5.1 mg/L

The substance is inherently biodegradable and has a log Kow of 3.62.

Based on these results the classification of the substance is Hazardous to the Aquatic Environment, category chronic 2 (H411 Toxic to aquatic life with long lasting effects).
