Additional information

As the PNECs are based on the limit of solubility of the substance in the ecotoxicity tests and are based on doses at which E/LC50s were not reached they will overestimate the toxicity of the substance leading to an exaggerated expression of the risk in the risk assessment.

Conclusion on classification

9.1.3 Short-term toxicity testing on fish: Hooftman & de Wolf (2004), OECD 203 and EU method C.1; LC50>water solubility

9.1.1 Short-term toxicity on invertebrates: Hooftman & de Wolf (2004), OECD 202 and EU method C.2; EC50>water solubility

9.1.2 Growth Inhibition Study on Aquatic Plants: Rufli (1988), OECD 201; ErC50 > water solubility

In accordance with the criteria outlined in Regulation EC No. 1272/2008 (CLP) and Directive 67/548/EEC (DSD), the substance does not meet the critieria for classification as dangerous to the environment.
