Abstract: Aluminum toxicity is known to be decreased by other factors, such as the presence of silicon. In this study, acute toxicity tests were performed on Daphnia magna to determine if magnesium and calcium carbonate are protective against aluminum toxicity. Magnesium carbonate eliminates acute toxicity, while calcium carbonate is protective at aluminum sulphate concentrations above 40 μM. The mechanism of protection is not fully understood, but the presence of carbonates may promote the formation of aluminate ions, a less toxic species of aluminum. These results could have implications in current research studying aluminum toxicity humans.
