alkylbenzenes, at concentrations up to and exceeding the water
solubility limit, had no short term effects on all three trophic levels
tested (fish, invertebrates and algae).Therefore,
the substance is not classified as acute aquatic hazard in accordance
with EU Classification, Labelling and Packaging of Substances and
Mixtures (CLP) Regulation No. 1272/2008.
the ECHA Guidance on the application of the CLP criteria (2015), which
recommends testing of complex substances using the Water
Accommodated Fraction (WAF) method, a GLP-compliant OECD 211 guideline
Daphnia magna study was conducted using the WAF dosing method
(Minderhout et al. 2013). In this study there were no biological or
reproductive effects noted. The
21-d NOEL is > 10 mg/L (WAF), the highest dose tested.
additional 21-day chronic study with Daphnia was conducted and resulted
in a NOEC of 0.0075 mg/L. However, this test exceeds the criteria, due
to the solvent concentration (1 mg/L) was above the recommended level
for solvent addition (< 0.1 mL/L) (OECD 211
It was therefore only used for the derivation of the PNEC (considering
its conservative value), but not for the environmental classification. The
long-term toxicity data are avilable for fish and algae as well, whcih
NOECs were both greater than the highest tested nominal concentrations. Based
on these results, the substance was not classified for chronic aquatic
hazard in accordance with EU
Classification, Labelling and Packaging of Substances and Mixtures (CLP)
Regulation No. 1272/2008.
