Special issue on the environmental risk assessment of alcohol ethoxylate nonionic surfactant

Abstract Alcohol ethoxylates (AE) are a common nonionic surfactant employed in consumer and industrial detergents worldwide.Commercial AE are typically complex mixtures composed of 4100 homologous…

Abstract Recent improvements in methodology for the determination of alcohol ethoxylates (AE) in effluents now enable measurement of the full range of AE components, at ng/L levels, in the same…

Abstract Pure homologues of [1- 14C] C12, C14, and C16 alcohols and the linear alcohol ethoxylates, AE [1- 14C alkyl] C13E9 and C16E9 were tested in a batch-activated sludge die-away system to…

Abstract Environmental monitoring indicates that the distribution of alcohol ethoxylate (AE) homologues in wastewater treatment plant (WWTP) effluents differs from the distribution in commercial AE…

Abstract Alcohol ethoxylates (AEs) are an important group of nonionic surfactants. Commercial AEs consist of a mixture of several homologues of varying carbon chain length (Cx) and degree of…

Abstract Traditionally, ecotoxicity quantitative structure–activity relationships (QSARs) for alcohol ethoxylate (AE) surfactants have been developed by assigning the measured ecotoxicity for…

Abstract An environmental risk assessment for alcohol ethoxylates (AE) is presented that integrates wastewater treatment plant monitoring, fate, and ecotoxicity research with a new application of…
