Abstract

Coal ash contains numerous contaminants and is the focus of regulatory actions and risk assessments due to environmental spills. We exposed Daphnia magna to a gradient of coal ash contamination under high and low food rations to assess the sublethal effects of dietary exposures. Whereas exposure to contaminants resulted in significant reductions in growth and reproduction in daphnids, low, environmentally relevant food rations had a much greater effect on these endpoints.

The present study was conceived in the Modeling Molecules to Organisms Working Group at the National Institute for Mathematical and Biological Synthesis, sponsored by the National Science Foundation through NSF Award DBI-1300426, with additional support from the University of Tennessee, Knoxville (USA). Experimental work at Lakeland University, Plymouth, Wisconsin (USA) was carried out by B. Wilder-Corrigan, M. Runge, and C. Larson with designated funds from C. Feldmann and the Lakeland Undergraduate Research Experience. The Oak Ridge National Laboratory is managed by UT-Battelle, for the US Department of Energy under contract DE-AC05-00OR22725. Andre Gergs's current address is Bayer, Monheim, Germany.
