Abstract: Cadmium is one of the most toxic heavy metals and is not an essential nutrient element for plant, animal and human being. There are mutual impacts between cadmium and many nutrient elements. The uptake of nutrient elements will be inhibited by cadmium contamination. On the contrary, adding appropriate nutrient elements will lower the toxicity of cadmium. Due to different character and function for each element, interactions between elements and cadmium express the otherness. Research for mutual impacts between cadmium and elements will provide scientific foundation for prevention of cadmium contamination.
