Additional information

The results for this study are taken from the SIDS Initial Assessment Report, For SIAM 4, Tokyo, Japan, 20-22 May 1996, as the full report was not able to be located. The results are considered reliable as a data source used to support the SIDs programme; results collaborate with acute results that could be located. The full report is available at

As the lowest chronic toxicity result, the 21 d-NOEC (reproduction) of Daphnia magna (0.32 mg/l) was adopted.

On the basis of the results noted in the study, classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008 stands as per the acute studies as follows:

N; R51/53 Dangerous for the environment; Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.

Chronic aquatic toxicity, Category 2; H411: Toxic to aquatic life with long lasting effects.
