Description of key information

No data on the long-term toxicity of the test substance on fish are available.

Key value for chemical safety assessment

Additional information

Acute tests on all three trophic levels were performed to examine the aquatic toxicity of the test substance. The results of short-term toxicity studies on fish and daphnids demonstrated that the L(E)C50-values are in the same range (19.2 mg/L for algae, 22.5 mg/L for fish and 42 mg/L for daphnids). The NOECs on the growth of algae (3.46 mg/L) and the reproduction of daphnids (3.08 mg/L) in long term studies were also determined to be in the same non-critical range. It is assumed that results of a long-term study on fish would also be in the same order of magnitude as the results of the provided long-term results on algae and daphnids. Therefore, and for reasons of animal welfare, a long term study in fish is not provided.
