Description of key information

LC50 = 24 mg/L for bluegill sunfish Lepomis macrochirus (EPA-660/3-75-009, static) exposed to Alcohols, C7-9-iso-, C8-rich.

Key value for chemical safety assessment

Additional information

Alcohols, C7-9-iso, C8-rich, produced a 96-hour LC50 value of 24 mg/l (nominal) with bluegill sunfish, Lepomis macrochirus. Supporting information is provided by a 96-hour measured LC50 of 14mg/L for a similar substance, 1 -octanol, for fathead minnow, Pimphales promelas; and also by acute aquatic toxicity values calculated using the neutral organics structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite; the results of which are consistent with the measured test data.
