Description of key information

EC50 (48 h) = 9 mg/L (Daphnia magna)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
9 mg/L

Additional information

The acute toxicity of 3 -Mercaptopropionic acid towards Daphnia magna was determined by Lebertz (2000) in a laboratory study according to OECD Guideline 202. Based on geometric mean measured test item concentrations of 0 h and 48 h test media samples, the 48 h EC0, EC50, and EC100

values for the mobility of the test substance to Daphnia magna were determined to be 2.4, 9, and 35 mg/L, respectively.
