In recent years, concerns have emerged regarding endocrine disruptors -chemicals that cause adverse effects by interfering with natural hormonal functions. This project focused on identifying the potential for estrogenic constituents in domestic wastewater effluents to induce changes in physiological responses (biomarkers) in fish, and on relating emerging assays for endocrine disrupting compounds (EDCs) to adverse effects on individuals or populations. This report provides environmental managers with a framework for evaluating potential endocrine disruption in wild fish exposed to effluents and increases understanding of the uses and limitations of biomarker measurements.
