Includes bibliographical references. "Residues of non-ionic surfactants such as alkylphenol ethoxylates and their metabolites in the environment have become a concern of late. These residues, readily found in the municipal sewage treatment plant effluents, are not only toxic to certain aquatic organisms but also weakly estrogenic and behave as endocrine disrupters. This report describes the synthesis of a metabolite of 4-tert-octylphenol ethoxylates and its determination in sewage effluents. This research supplement our current work on the assessment of the occurrence, fate and pathway of nonylphenol ethoxylates (a PSL 2 substance) in the Canadian environment"--Management perspective.
