The objective of the project was to provide information on the oestrogenic chemical profile and activity of 43 priority sewage treatment works effluents. The data collated in this study will be used in a separate risk assessment of the impacts of steroid discharges. That risk assessment will inform the selection of sites for an endocrine disruption demonstration programme to evaluate treatment options. In this report, comparisons of the predicted concentrations for the natural and synthetic steroids with the proposed Predicted No Effect Concentrations (PNECs) for these compounds indicate that a number of these effluents even following dilution, would result in receiving water steroid concentrations that could produce oestrogenic effects in resident fish populations downstream of the discharges.
