Description of key information

LC50 (96 h) = 98 mg/L (Brachydanio rerio)

Key value for chemical safety assessment

LC50 for freshwater fish:
98 mg/L

Additional information

In a semi-static laboratory study by Lebertz (2000) the short-term toxicity to Brachydanio rerio of the test material 3-mercaptopropionic acid (3-MPA)

has been determined in accordance with the OECD Guideline 203. Based on measured test item concentrations in the 24 h old test media, the resulting 96 h LC0, LC50 and LC100 values were 15, 98, and 174 mg/L, respectively.
