Mixture toxicity of mercury and cadmium on the mineral content of the Indian major carp, Labeo rohita

Industrial activities, domestic wastes and agriculture release increased quantities of heavy metals into the environment. As they cannot be degraded, they accumulate in organisms and cause toxic effects. When present in different combinations, their effects can be additive, synergistic, or antagonistic. Hence the present work has been carried out to study the mixture toxicity of mercury and cadmium on the mineral content of the fish, Labeo rohita after ten days of exposure to sublethal concentrations. Except potassium content, the two selected metals were antagonistic in their effects.
