Description of key information

Based on QSAR calculations using the weighted measured log Kow value, the C8 alcohol is expected to have a 14-day EC50 of 178.328 mg/kg soil.

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:

Additional information

There are no experimental data using standard testing procedures that can be used for assessing the terrestrial hazard of isooctanol. However, there is a calculated (ECOSAR) earthworm 14-day LC50 value of 178.328 mg/kg soil. The modeled earthworm data would suggest that Alcohols, C7 -9 -iso-, C8 -rich has a low order of toxicity to soil dwelling organisms. However, it is possible to qualitatively conclude, based on available QSAR data, that this substance does not pose an unacceptable risk to the terrestrial compartment.
