Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
404 mg/L

Additional information

Data on the acute toxicity of the substance to aquatic invertebrates are not available. The evaluation is based on a study conducted with the structural analogue glyoxal (CAS 107-22-2). The substance is characterised by comparable physio-chemical properties e.g. water solubility, low log Pow and log koc. Therefore the read-across is deemed valid. The toxicity of the analogue substance to Daphnia magna was tested in a guideline study following EU method C.2. The test organisms were exposed to the substance for 48 hours. Based on the mobility of D. magna an EC50 of 404 mg/l refering to nominal test substance concentration was detected (BASF AG, 1988).
