Additional information

No adverse effects were noted for any species tested and therefore, the determination of relative sensitivities could not be made. However, the freshwater species tested at the lowest nominal concentration was the green algae Pseudokirchnerella subcapitata, with a 72 hour EC₅₀ of >0.1 mg/L (highest concentration tested for this species). Using an assessment factor of 100 (proposed when one long-term NOEC is available) as presented in Table R.10-4 of REACH guidance document R.10 (May 2008), the resulting PNEC_{aquatic- freshwater} is > 0.001 mg/L. If exposure were to occur via intermittent releases, the PNEC_{aquatic – intermittent releases} would also be >0.001mg/L, based on the EC₅₀forPseudokirchnerella subcapitataand an assessment factor of 100 (Section R.10.3.3 of REACH guidance document R.10 (May 2008)).

In the absence of data for marine species the PNEC_{aquatic-marine water} has been calculated using freshwater datain lieu.Using an assessment factor of 1000 (proposed when one long-term NOEC is available) as presented in Table R.10-5 of REACH guidance document R.10 (May 2008), the resulting PNEC_{aquatic- marine water} is > 0.0001 mg/L.

It should be noted that because no adverse effects were determined for any of the aquatic species tested, and that all tests were conducted at concentrations exceeding the water solubility limit of 0.02 mg/L, it would be reasonable to conclude that, in reality, the PNEC for aquatic species should be >= 0.02 mg/L.  However, as noted above, the assessment has been conducted to provide a conservative evaluation of ecological effects so that the very low calculated PNEC values will be applied further.

No data on soil or sediment dwelling organisms are available or considered to be required, Nonetheless PNECs were derived using equilibrium partitioning methods as described in Technical Guidance Document on Risk Assessment. Part II .  

Conclusion on classification

Although the substance is classified as not readily biodegradable, the aquatic BCF is <100 and the chronic NOEC for Daphniais above the water solubility limit thus R53 (May cause long-term adverse effects in the environment) is not considered to be required.
