This report reviews the available data on the occurrence, environmental fate and toxicity of alkylphenol ethoxylate (APnEO) surfactants and their breakdown products, resulting from degradation during sewage treatment and in surface waters. The report goes on to prioritis the breakdown products arising from alkylphenol ethoxylates with respect to the risk they pose to aquatic life. Finally, options for developing water quality standards for these substances are explored and proposals for the development of Environmental Quality Standards for the protection of aquatic life in surface waters are described in detail.
