WebTo resolve some of the remaining ambiguities, we also used a fecundity assay to show that iso-propanol is more toxic than ethanol, and a lethality assay to show that iso-butanol is more toxic than iso-propanol. Most of the endpoints studied are consistent with the following order of toxicity: iso-butanol > iso-propanol > ethanol > or = methanol.
