Water column toxicity of several DDT congeners to Hyalella azteca, and its implications for contaminated sediment assessment

This dataset is associated with an article submitted for publication in a peer reviewed journal titled "Water column toxicity of several DDT congeners to Hyalella azteca, and its implications for contaminated sediment assessment". To inform ecological risk assessment for freshwater sediments, we tested the toxicity of water column exposure to six DDT congeners, specifically the p,p’ (4,4’) forms of DDT, dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), and dichlorodiphenylchloroethylene (DDMU), as well as the o,p’ (2,4’) forms of DDT and DDD. The test organism was the amphipod Hyalella azteca, exposed for 7 days and assessed for changes in survival and growth. It includes chemical and biological data collected during those tests as well as the results of regression analyses used to calculate of median and 20% effect concentrations for survival and biomass gain. This dataset is associated with the following publication: Mount, D., L. Burkhard, J.R. Hockett, C. Holloway, S. Howe, J. Jenson, S. Kadlec, A. Kasparek, T. Lahren, K. Lott, E. Piasecki, J. Swanson, and L. Votava. Waterborne toxicity of several dichlorodiphenyltrichloroethane congeners to Hyalella azteca and its implications for contaminated sediment assessment. ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY. Society of Environmental Toxicology and Chemistry, Pensacola, FL, USA, 44(3): 728-736, (2025).
