Description of key information

No data concerning the long term toxicity of the test substance to fish is available.

Key value for chemical safety assessment

Additional information

No toxic effects were observable in an acute study of the test substance on Brachydanio rerio (CIBA-GEIGY 1988a). This result is supported by another short term study on orange-red killifish (MITI 1992). Furthermore, an environmental exposure assessment was performed in order to determine possible risks of the test compound to all environmental compartments. According to the results of the exposure assessment, all the relevant uses of the test substance are considered to be safe with a Risk Characterization Ratio below 1.

Due to these calculations, the lack of toxic effects in the acute studies, and for reasons of animal welfare, the risk to fish is expected to be low and long term studies are not provided.
