Integrated coastal effects study: Synthesis of findings
Abstract Municipal wastewater discharges constitute a major source of contaminants of emerging concern (CECs) to coastal waters, yet uncertainty exists regarding their linkage to adverse biological effects such as endocrine disruption. Limited information is available concerning the types and fate o...

Fish plasma hormone analyses suggested the presence of physiological effects, including a reduced stress response, altered estrogen synthesis or estrogenic exposure, and reduced thyroxine. Most fish responses were found at all sites and could not be directly associated with effluent discharges. However, concentrations of thyroxine were lower at all discharge sites relative to the reference, and estradiol concentrations were lower at three of the four outfall sites. The physiological responses found were not associated with adverse impacts on fish reproduction or populations. Interpretation of molecular and physiological measurements in field organisms such as those used in the present study is challenging because of a lack of information on baseline conditions and uncertain linkages to apical endpoints such as survival and reproduction.
