Description of key information

Toxicity to microorganisms was assessed in an OECD 209 test for the structural analog 1-nitropropane.

Key value for chemical safety assessment

EC50 or LC50 for microorganisms:
310 mg/L
EC10, LC10 or NOEC for microorganisms:
72 mg/L

Additional information

The effect of 1 -nitropropane (structural analog to 2 -nitropropane) on the respiration of activated sewage sludge gave a 30-Minute EC50 of 310 mg/L. The No Observed Effect Concentration (NOEC) after 30 minutes exposure was 72 mg/L.
