Combined action of cadmium and selenium on two marine dinoflagellates in culture, Prorocentrum micans Ehrbg. and Crypthecodinium cohnii Biecheler

, : Combined action of cadmium and selenium on two marine dinoflagellates in culture, Prorocentrum micans Ehrbg. and Crypthecodinium cohnii Biecheler. Journal of Protozoology, 331: 42-47

The combined action of cadmium and selenium was investigated in two unicellular marine phytoplankton organisms, Prorocentrum micans Ehrbg. and Crypthecodinium cohnii Biecheler, in culture. When present simultaneously in low concentrations, the toxicity of Cd and Se is decreased (antagonism) whereas if one of these elements is present at high concentration, especially for a long period, their toxicity is increased (synergism) more than if they were separate. This interaction affected cell organelles in the following ways: vacuolation development of chloroplast pyrenoids, and elicitation of lipid vesicles, starch vesicles, giant mitochondria, and lysosomes. Possible competition between these two elements for binding sites is discussed.
