EC number: 448-250-3
CAS number: -
No data evaluating the chronic toxicity of 2 -Hexyl-2 '-hydroxy-5
(AF-654) to fish are available. The environmental exposure
assessment performed for this substance (see Chapters 9 and 10 of the
CSR for detailed information) shows that the Risk Characterization
Ratios (i.e. PEC/PNEC ratio) in the aquatic compartment (freshwater and
marine) are < 1 and therefore, under the current exposure conditions,
AF-654 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 a
worst-case approach for exposure calculations.
