For the 3 trophic levels (fish,
invertebrates (Daphnia) and algae), studies on the short-term toxicity
of XDI and XDA have been evaluated
(the long-term toxicity has not been investigated). The results as
expressed in measured concentrations XDA have been converted to XDI
concentrations for the purpose of CLP classification (Guidance on the
application of the CLP criteria, 188.8.131.52.1.).
- 96h-LC50 for
freshwater fish: 120.9 mg XDI/L
- 48h-EC50 for
freshwater invertebrates: 13.4 mg XDI/L
- 72h-ErC50 for
freshwater algae: 43.5 mg XDI/L
- 72h- ErC10 for
freshwater algae: 29.8 mg XDI/L
As the lowest L(E)C50
value is 13.4 mg XDI/L and XDA, the main hydrolysis product, is not
rapidly degradable, XDI should be classified as Harmful to aquatic life
with long lasting effects (H412) in accordance with the CLP Regulation
1272/2008 (as amended by Regulation 286/2011) (Long-term aquatic hazard
Please note that XDA has been registered
with the same classification in its REACH lead registration dossier.
should be classified as harmful to aquatic organisms, may cause
long-term adverse effects in the aquatic environment (risk phrases
R52/R53) according to Directive 67/548/EEC (DSD).
