Chronic Toxicity Of Binary‐Metal Mixtures Of Cadmium And Zinc To Daphnia Magna, Edgar Pérez, Tham C. Hoang
School of Environmental Sustainability: Faculty Publications and Other Works
The present study characterized the chronic effect of binary‐metal mixtures of cadmium (Cd) and zinc (Zn) on Daphnia magna. The titration design was chosen to characterize the 21‐d chronic effects of the binary‐metal mixtures on survival, growth, reproduction, and metal accumulation in D. magna. Using this design, increasing concentrations of Zn (10, 20, 40, 80, 120, 160, and 200 μg/L) were titrated against a constant concentration of 1.5 μg/L Cd. The results demonstrated that Cd was highly toxic to D. magna. In a mixture with Cd and Zn, sublethal concentrations of 10 and 20 μg/L Zn were …

Non-Additive Toxicity Of Bi-Metal Mixtures To Fathead Minnows, Natalie Rae Lynch
Master's Theses
Much research has been conducted to assess the toxicity of metals to aquatic organisms. Most of the research has focused on the toxicity of individual metals. Recently, attention has been paid to metal mixture toxicity because metals are usually present as mixtures in contaminated environments. The literature review indicates that metal mixtures may be additive, synergistic, or antagonistic to freshwater species. However, the data is not consistent and is dependent on the metal and organisms. The goal of this research is to use a systematic experimental design to characterize the toxicity of Cu, Zn, Cd and Ni mixtures to Pimephales …
