Additional information
Conclusion on classification
As the short-term toxicity results are >1 mg/L, the substance does not need to be classified for acute environmental toxicity. As the substance is readily biodegradable and the lowest long-term toxicity result is 0.61 mg/L, the substance needs to be classified in Category 3 for chronic environmental toxicity.
