Description of key information

In an OECD 209 study, conducted to GLP, the 3-hour EC50 of NDC for the respiration of activated sewage sludge micro-organisms is greater than 1000 mg/L. The 3-hour No Observed Effect Concentration (NOEC) is 1000 mg/L (Harlan Laboratories Limited, 2013).

Key value for chemical safety assessment

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

Additional information

Acute toxicity to microorganisms:

In an OECD Guideline 209 study, conducted according to GLP, the 3 -hour EC50 of NDC for the respiration of activated sewage sludge micro-organisms is >1000 mg/L. The No Observed Effect Concentration (NOEC) is 1000 mg/L (Harlan Laboratories Limited, 2013).
