Additional information

Three short-term studies were available for the three standard aquatic organisms (fish, daphnia and algae). All three studies showed no toxicity up to the highest concentration tested being 100 mg/L. The substance did not show toxic effects to to fish, aquatic invertebrates at its saturation level in the respective test medium. PNECs could not be derived as the substance showed no 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.

No toxicity was observed in a OECD 209 study at the highest dose tested. No PNEC can thus be derived.

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.

As the substance is insoluble in water, concentrations which are toxic to aquatic organisms will 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

Classification

T002675 is not considered to be biodegradable. Three short-term studies were available for the three standard aquatic organisms (fish, daphnia and algae). All three studies showed no toxicity up to the highest concentration tested being 100 mg/L. The substance did not show toxic effects to fish, aquatic invertebrates at its saturation level in the respective test medium. Classification should only be based on toxic responses observed in the soluble range, therefore the substance is not expected to be chronically toxic to aquatic organisms either based on the results of the algae study (NOEC >= solubility limit). Furthermore, the substance does not have a significant potential to bioaccumulate which is further evidence that the substance does not have the potential to be chronically toxic to aqautic organisms. Since the test substance showed not toxic effects within the range of solubility and is not bioaccumulative due to a log Kow of 1.05, the aquatic chronic category 4 classification according to Regulation (EC) N° 1272/2008 is not justified. In conclusion, none of the criteria of Regulation (EC) N° 1272/2008 have been met.
