Based on the aquatic toxicity data, the test substance is not classified
as hazardous to the environment in accordance with Regulation (EC) No
An EC50 of 14.5 mg/L for Ceriodaphnia dubiahas been reported for
photo-induced degradation products of NTO generated using a high
concentration of NTO (1507 mg/L). At lower concentrations (111 mg/L) NTO
showed no toxicity toCeriodaphnia dubia(EC50 >111 mg/L) when
subjected to photo-induced degradation conditions (UV irradiation).
However, such specific conditions (UV light and high concentrations) are
not considered a firm basis for the classification of NTO.
