In the terrestrial environment, Cd is known as a notorious toxin, causing phytotoxicity and human diseases such as renal dysfunction, osteoporosis, and cancers. The best known Cd-induced disease, Itai-itai (renal tubular osteomalacia), is caused by chronic exposure to Cd via consumption of rice grown in Cd-contaminated paddy soil.展开更多
