PRESENCE AND BEHAVIOR OF LINEAR ALKYLBENZENESULFONATES AND ALKYLPHENOL ETHOXYLS IN AQUEOUS-SOLUTIONS - UPDATE

This article reviews recent knowledge about the fate in the aquatic environment of two extensively used classes of surfactants: the linear alkylbenzenesulfonates (LAS) and the alkylphenol ethoxylates (APE). From an analytical point of view, the preference for specific determination of LAS and APE compounds rather than for global determination of anionic or nonionic surfactants is argued. Data are given on concentration levels and comportment of IAS and APE in sewage effluents and in aquatic environment, with reference to marine environment. Finally, their biodegradation, which is the main process governing their fate in the environment, is specially investigated.
