Key value for chemical safety assessment

Additional information

No data evaluating the chronic toxicity of ethyl 3,5-dichloro-4-hexadecyloxycarbonyloxybenzoate (AF-366) to aquatic invertebrates are availbale. The environmental exposure assessment performed for this substance (see Chapters 9 and 10 of the CSR for detailed information) shows that the Risk Characterisation Ratios (i.e. PEC/PNEC ratio) in the aquatic compartment (freshwater and marine) are < 1 and therefore, under the current conditions, AF-366 does not pose a risk to aquatic organisms and further testing is not deemed necessary according to Regulation (EC) No. 1907/2006, Annex XI, section 3. Due to the absence of chronic experimental data and the lack of toxic effects in the acute aquatic toxicity tests, surrogate PNEC values have been derived using the water solubility value as worst-case for exposure calculations.
