Additional information
Conclusion on classification
The substance is not acutely toxic to aquatic plants, invertebrates or fish. The substance is chronically toxic to aquatic plants. The 7-d NOErC (frond number) to Lemna sp. is 0.208 mg/L. The substance is not biodegradable and therefore classified as Aquatic Chronic 2 (H411).
