Description of key information

No toxic effects occur within the range of solubility.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

In a 3-hr acute toxicity study sewage sludge micro-organisms were exposed to the test item at nominal concentrations of 62.5 to 1000 mg/L in a dose response design in accordance with OECD 209. The EC10 and EC50 value based on respiration rate was > 1000 mg/L after a 3 h contact time.

This toxicity study is classified as acceptable and satisfies the guideline requirements for OECD 209 toxicity study.
