EC number: 807-130-4
CAS number: 53716-82-8
Daphnia 16-day NOEC: 1575 mg/l (predicted value).
No measured long-term toxicity to freshwater invertebrates data are
available for the registration substance. The data requirement has been
fulfilled using QSAR predicted data.
form of the registered substance, the Gem Diol, is the relevant species
for aquatic assessment, therefore the properties of the Gem Diol have
been used as the input parameters for the QSAR.
A 16-day ChV of 2818 mg/l has been determined for the effects of the
test substance on Daphnia sp. using ECOSAR v2.0 for the
prediction of the aquatic toxicity of neutral organics. The ChV can be
converted to a NOEC value by dividing the ChV by 1.789 (this is a worst
case calculation reflecting a spacing factor of 3.2).
The predicted NOEC value for the effects of the aqueous form of the
registration substance, the Gem Diol, on Daphnia sp. is therefore
2818/1.789 = 16-day NOEC 1575 mg/l.
Please see the QMRF report attached in the Endpoint Study Record for
further details on the prediction method.
