Key value for chemical safety assessment

Additional information

The toxicity on microorganisms was tested in cell multiplication tests with Chilomonas paramaecium [Bringmann et al., 1980] and Pseudomonas putida [Bringmannn and Kuehn, 1977]. The 48-hour EC05 value for Chilomonas paramaecium was measured to be > 400 mg/L. For Pseudomonas putida the 16-hour EC50 value was determined to be > 10000 mg/L.
