There is limited data available on the toxicity of 2 -butoxyethyl
acetate to algae, but sufficient to meet the requirements of the end
point. Two experimentally derived results are available, both showing
relatively low toxicity to the species. The study used as the key study
shows the lower of the two results and is to a modern protocol. It is
deemed reliable, although the available publication is not particularly
detailed. The data is sufficient to judge with confidence that the
substance is of low toxicity to algae. The data is also sufficient to
provide a NOEC for use in deriving the PNEC for the aquatic compartment.
