For a heavy metal such as cadmium, the specific technique used is phytoextraction: certain plant species, called hyperaccumulators, are able to absorb cadmium from the soil through their root system and translocate it upward, concentrating it in their above-ground shoot tissue, often at levels many times higher than in the surrounding soil.
