Description of key information

Acutely harmful to aquatic invertebrates

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
65 mg/L

Additional information

The acute toxicity to aquatic invertebrates was tested in several studies. The key study investigating the immobilisation of Daphnia magna was conducted according to EU method C.2 under static conditions with analytical monitoring. The 48 -h EC50 was determined to be 65 mg/L (measured). This value indicates that 2 -aminoethanol is acutely harmful to aquatic invertebrates.

Further studies support this conclusion:

In a semi-static Daphnia magna immobilisation test according to OECD 202 and under GLP with analytical monitoring, the 48 -h EC50 was 97.26 mg/L (nominal, analytically verified; NITE, 1997). In a further study with Daphnia magna, the 48 -h EC50 was determined to be 32.6 mg/L. However, the test was performed according to a lab procedure which was not further specified in the report. Information on test performance and analytical monitoring are lacking (UCC, 1988).

The mean value of these three studies (65.0 mg/L) is identical with the effect value for the Huels (1997) study.

Libralato et al. (2010) tested a saline species (Artemia franciscana). The 24 -h EC50 was determeined to be 43 mg/L and is within the same range as the freshwater data for 2 -aminoethanol.
