Additional information

A number of studies have been carried out using multiple species, both fresh and salt water. One study in two species is sufficiently well reported to judge it as reliable and this is used to derive the key parameters. All the other available experimental studies, whilst not individually robust, report data that is consistent with the key study and provide strong evidence that 2 -(2 -butoxyethoxy)ethanol is practically non-toxic to fish over the acute timeframe.
