Description of key information

In a test according to the German guideline published in: "Bewertung wassergefahrdender Stoffe" the 18-h NOEC in Pseudomonas putida is >20000 mg/l.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
20 000 mg/L

Additional information

Reliable test data are available for toxicity to microorganisms. In a near guideline test with Pseudomonas putida an 18-h NOEC of >20,000 mg/l was determined in a growth inhibition test. Nominal values were reported (The Dow Chemical Company, 1992). This value will be used in the assessment.
