Description of key information

With high probability 2,2’,2’’-nitrilotriethanol is acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
609.88 mg/L

Additional information

The key study identified for the acute toxicity to aquatic invertebrates is a test performed by Warne et al. (1999) according to ASTM Designation E1192. Using Ceriodaphnia dubia as test species in a static procedure an EC50 of 609.88 mg/l after 48 hours of exposure was calculated related to the nominal concentrations. The test concentrations are not analytically verified. The substance is miscible with water, has a low vapour pressure, and a low Henry's Law constant ; therefore, the test concentrations are assumed to be stable over the exposure period of 48 hours.

Hence, the chemical is with high probability be acutely not harmful fo invertebrates.

Other data which are available for 2,2’,2’’-nitrilotriethanol are disregarded and shout not be used for risk assessment purposes mainly due to the insufficient exposure duration.
