Description of key information
The EC50 and NOEC for nitroethane were determined based on the results for the structurally similar compound 1-nitropropane. The results for 1-nitropropane were corrected assuming an equivalent response on a molar basis.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 261 mg/L
- EC10 or NOEC for microorganisms:
- 61 mg/L
Additional information
The effect of the test material 1 -nitropropane on the respiration of activated sewage sludge gave a 30-Minute EC50 of 310 mg/L. A NOEC was determined which is equivalent to the EC15 value determined from an inhibition response curve and percentage inhibition values for the test material. The No Observed Effect Concentration (NOEC) after 30 minutes exposure was 72 mg/L. Assuming an equivalent response on a molar basis, corresponding values for nitroethane for a 30 minute contact time would be EC50 = 261 mg/L and NOEC = 61 mg/L.
