Temporal Variation in the Estrogenicity of a Sewage Treatment Plant Effluent and its Biological Significance
MARTINOVIC, D., J. S. DENNY, P. K. SCHMIEDER, G. T. ANKLEY, AND P. W. SORENSEN. Temporal Variation in the Estrogenicity of a Sewage Treatment Plant Effluent and its Biological Significance. ENVIRONMENTAL SCIENCE & TECHNOLOGY. American Chemical Society, Washington, DC, 42:3421-3427, (2008).
The overarching objective of the present study was to determine whether fluctuating exposure regimens (similar to those encountered in the wild) exert effects on fish behavior and reproduction comparable to constant regimens commonly used for laboratory assessment of EE effects.
This paper describes variations in the estrogenic potency of effluent from a "model" wastewater treatment plant in Duluth, MN, and explores the significance of these variations relative to sampling approaches for monitoring effluents and their toxicity to fish.
