Toxicity Profile

Route of Exposure

Oral (4) ; inhalation (4) ; dermal (4)

Mechanism of Toxicity

Cadmium 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)

Metabolism

Cadmium 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 Values

LD50: 2100 mg/kg (Intraperitoneal, Mouse) (11)

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

1, carcinogenic to humans. (8)

Uses/Sources

Cadmium telluride is used as a semiconductor in solar cells and in infrared, x-ray, and gamma-ray detectors. (10)

Minimum Risk Level

Acute 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 Effects

Chronic 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)

Symptoms

Acute 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)

Treatment

Cadmium poisoning is treated by removal from exposure and supportive care. If ingested, induced vomiting or gastric lavage may be performed. (9)
