Cadmium was discovered in 1817 and occurs naturally with zinc. It is used in electroplating, pigments, plastics, and batteries. Cadmium is poorly absorbed through digestion but is readily absorbed through inhalation, with the lungs and kidneys accumulating about 50% of the body's cadmium load. Chronic cadmium toxicity primarily affects the kidneys, causing proteinuria and damage related to amino acids and phosphates, as well as increased urinary calcium and risk of kidney stones. Other chronic effects include lung damage like emphysema and cancer, interference with copper metabolism causing anemia, tooth discoloration, and prostate cancer. Treatment focuses on chelating agents to increase urinary
