DescriptionCadmium iodide is an iodide of cadmium that can be made by heating cadmium with iodine. It is used in lithography, photography, electroplating and the manufacturing of phosphors. Cadmium is a transition metal and chemical element with the symbol Cd and atomic number 48. It is found naturally in the earth's crust, though rarely on it's own. (4, 10)

Toxicity Profile
Route of ExposureOral (4) ; inhalation (4) ; dermal (4)
Mechanism of ToxicityCadmium initially binds to metallothionein and is transported to the kidney. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Accumulation of cadmium in the kidney results in increased excretion of vital low and high weight molecular proteins. Cadmium is a high affinity zinc analog and can interfere in its biological processes. It also binds to and activates the estrogen receptor, likely stimulating the growth of certain types of cancer cells and causing other estrogenic effects, such as reproductive dysfunction. Cadmium causes cell apoptosis by activating mitogen-activated protein kinases. (5, 1, 2, 3)
MetabolismCadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (4)
Toxicity ValuesLD50: 4708 mg/kg (Oral, Rat) (11)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)1, carcinogenic to humans. (8)
Uses/SourcesCadmium iodide is used in lithography, photography, electroplating and the manufacturing of phosphors. (10)
Minimum Risk LevelAcute Inhalation: 0.00003 mg/m3 (7) Chronic Inhalation: 0.00001 mg/m3 (7) Intermediate Oral: 0.0005 mg/kg/day (7) Chronic Oral: 0.0001 mg/kg/day (7)
Health EffectsChronic exposure to cadmium fumes can cause chemical pneumonitis, pulmonary edema, and lung diseases such as bronchitis and emphysema. Cadmium also accumulates in the kidneys, causing permanent damage. Loss of bone density also occurs. (4)
SymptomsAcute inhalation of cadmium fumes results in metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Ingestion of cadmium causes vomiting and diarrhea. (4)
TreatmentCadmium poisoning is treated by removal from exposure and supportive care. If ingested, induced vomiting or gastric lavage may be performed. (9)
