key study is available for each of the following endpoints:
acute toxicity of the meta-isomer to Danio rerio for a duration
of 96 hours was assessed according to the OECD guideline 203. The
results of the study showed that under valid static test conditions, the
maximum concentration causing no mortality and the 96 h-LC50 of the test
item to zebra fish are both greater than the nominal concentration of
150 mg/L (measured concentration 147 mg/L).
acute toxicity to Daphnia magna was evaluated for the meta-isomer
as well as for the mixture of both isomers according to OECD Guideline
no immobilization was observed throughout both tests, the 48h-EC50 of
the registered substance is upper than the highest tested concentration
(i.e. 150 mg/L tested with meta-isomer) expressed as nominal
study was performed with the m/p diol mixture according to OECD
Guideline 201. The 72h-EC50 for average specific growth rate and yield
could not be calculated due to the lack of fractional inhibition, and it
is therefore estimated to be > 100 mg/L. The NOEC was estimated to be
As a consequence, the registered
substance, which has shown a lack of toxicity to aquatic organisms at
the highest tested concentration of 100 mg/L and has a low log Kow
value, is not classified for environmental purpose. The
PNECfreshwater was thus not derived.
