Additional information

Three short-term studies were available for the three standard aquatic organisms (fish, daphnia and algae). The substance did not show toxic effects to fish and aquatic invertebrates up to the highest concentration tested (100% of a SS) in the respective test medium. Some effects were observed in the algae study however inhibition was below 10% up to and including the highest average concentration of 10 mg/L. Therefore, the effects were biologically not relevant.

For growth rate inhibition the 72-h EC10, the 72-h EC20 and the 72-h EC50 could not be calculated because the observed effects were below 10%.

PNECs could not be derived as the substance showed no biologically relevant toxic effects in studies performed in the range of its solubility. At the present state of knowledge, no negative ecological effects are expected. The substance is not expected to pose an unacceptable risk to the aquatic environment since it is not harmful to aquatic organisms up to its limit of solubility in water and there is expected to be very low aquatic exposure based on its very low solubility in water.

As there are no tests on sediment and soil dwelling organisms available, and as no PNEC aquatic could be derived, no PNEC values for soil and sediment can be derived either by using assessment factors or by the equilibrium partitioning method.

Concentrations which are toxic to aquatic organisms will likely not be reached. This is demonstrated in the available acute ecotoxicity studies. The substance will therefore not be classified for environmental hazards, based on the available information.

Conclusion on classification

No toxicity of the substance in the range of its solubility has been recorded in any of the three acute studies. In all trophic levels no toxic effects occurred up to the limit of solubility in the respective test media. Therefore, the test substance can be considered as not toxic to aquatic organisms and not posing an aquatic toxicity hazard. Furthermore, the substance does not have a significant potential to bioaccumulate. Since the test substance showed no toxic effects within the range of solubility and is not bioaccumulative due to the log Kow of 2.7 no acute or chronic classification according to Regulation (EC) No 1272/2008 is justified. Although the substance is considered as not very water-soluble and does not rapidly biodegrade, the "safety net" (Cat. chronic 4) also does not apply, as the log Kow is =<4 indicating a low potential for bioaccumulation. In conclusion, none of the criteria of Regulation (EC) No 1272/2008 have been met. Therefore, it is proposed that the substance is not classified for environmental hazards.
