Key value for chemical safety assessment

Additional information

No short term toxicity to fish data is available for the substance alcohols, C9 -C11 (odd numbered), branched and linear. However, data are available for C9, C11 and C9 -C11 multi-constituent substances.

A reliable 96h LC50 value of 5.7 mg/L has been determined for the effects of nonan-1-ol on mortality of the fish Pimephales promelas. Other reliable short term toxicity tests show the LC50 values for nonanol to be in the range 5.7 and 18 mg/L.

A reliable 96h LC50 value of 1 mg/L has been determined for the effects of undecan-1 -ol on mortality of the fish Pimephales promelas. Another reliable short term toxicity tests with fish shows the LC50 value to be 4.6 mg/L, while an estimated LC50 is 1.7 mg/L.

A reliable 96 h LC50 value of 6.3-10 mg/L has been determined for the toxicity of Alcohols, C9-11-linear and branched with the freshwater fish O. mykiss. The LC50 is reported as a range due to the steepness of the dose response curve.

A 96h LC50 value to 5.8 mg/L has been determined for the effects of the Alcohols, C9-11-linear and branched on mortality of the marine fish S. maximus.

The results are read-across to alcohols, C9 -C11 (odd numbered), branched and linear.
