Short-term aquatic toxicity data are available for three trophic levels
(fish, invertebrates and algae). The short-term fish studies show
LC/EC50 values greater than the Water Accommodated Fraction (WAF) or the
highest nominal concentrations. Therefore, the substance does not need
to be classified for acute aquatic hazard in accordance with CLP
Regulation No. 1272/2008.
Long-term toxicity data are available for three trophic levels (fish,
invertebrates and algae). For the long-term data, the NOEC values were
greater than the Water Accommodated Fraction (WAF) or the highest
nominal concentrations. For aquatic invertebrates, an additional 21-day
chronic study with Daphnia exposed to LAB, the most water soluble
component of HAB, still resulted in an EC50 of 0.012 mg/L and a NOEC of
0.0075 mg/L. While this latter value exceeds the criteria, it was
accomplished only by testing the most water soluble component of HAB and
then further artificially enhancing solubility through use of acetone as
a solvent. It was therefore only used for the derivation of the PNECs
and not for the environmental classification. Therefore, the substance
does not need to be classified for chronic aquatic hazard in accordance
with CLP Regulation No. 1272/2008.
