Effect of molybdenum on other trace elements - iodine, manganese and tungsten, arsenic and selenium

Effect of molybdenum on other trace elements - iodine

The effect of molybdenum on iodine metabolism in rabbits was to cause a decrease in the initial rate of uptake of iodine by the thyroid [Robinson et al., 1965]. More iodine was retained in the plasma of molybdate-fed rabbits. In connection with iodine metabolism it is of interest that in certain areas where goitre is endemic in human beings it was found that the molybdenum/copper ratio in food was greater than in other areas although there was no relationship between the incidence of goitre and the individual concentrations of molybdenum and copper [Tsvetkova, 1969].

Effect of molybdenum on other trace elements - manganese and tungsten

Various workers have reported metabolic antagonisms between molybdenum and manganese and molybdenum and tungsten.

Effect of molybdenum on other trace elements - arsenic and selenium

The sublethal interactive effects of arsenic (As), molybdenum (Mo), and selenium (Se) on Ceriodaphnia dubia using four levels (zero, IC12.5, IC25, and IC50 values) of each metal was performed on C. dubia survival and fecundity. Molybdenum and As in binary combinations were strongly antagonistic in their effects on C. dubia, even at their respective IC50 concentrations. The addition of Se to As-Mo mixtures significantly reduced survival and reproduction. The IC50 concentrations of either Mo or Se significantly reduced fecundity in all binary and tertiary mixtures.
