Chronic Toxicity Of Binary Metal Mixtures Of Cadmium-Zinc And Cadmium-Nickelon Daphnia Magna, Edgar Ramiro Perez
Chronic Toxicity Of Binary Metal Mixtures Of Cadmium-Zinc And Cadmium-Nickelon Daphnia Magna, Edgar Ramiro Perez
Master's Theses
This study characterizes binary-metal mixture effects of cadmium (Cd2+) + zinc (Zn2+) and Cd2+ + nickel (Ni2+) on Daphnia magna. Although acute studies have shown protective Ni2+ (Traudt et al. 2016) and Zn2+ effects (Meyer et al. 2015) against Cd2+ toxicity, no study has fully characterized a protective effect on D. magna at several endpoints (survival, reproduction, growth, and accumulation) on a chronic study. In this study, the titration design was selected to characterize the 21 day (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 …
