Description
Cadmium (Cd) is an inorganic compound with an average molecular weight of 112.41 g/mol. It is a solid at room temperature and is exogenous in origin. Cadmium belongs to the homogeneous transition metal compounds, a class of homogeneous metal compounds within the inorganic compounds. In industrial applications, it serves as a surface modifier and a degradant or impurity. It is used in various plastics, including High-Density Polyethylene, Low-Density Polyethylene, Expanded polystyrene, Polyamide, Polyurethane, and Acrylonitrile butadiene styrene. Additionally, it is present in Polyvinyl Chloride, Polystyrene, High impact polystyrene, and Polypropylene, and is released in Polycarbonate and Polyethylene Terephthalate. Cadmium is found in or released from 14 recorded sources, including food contact materials, fermentation processes for beer, cigar cigarettes, non-electric simulated smoking devices, and electrical and electronic equipment such as antennas, discharge lamps, electric switches, electrically stimulated smoking devices, and fixed capacitors. Recorded exposure routes include oral, inhalation, and touch. Regarding health effects, cadmium is associated with proteinuria (PMC9774004). The compound interacts with 18 recorded protein targets. It binds to and activates the estrogen receptor (ESR1) and estrogen receptor beta (ESR2), likely causing reproductive dysfunction and stimulating the growth of certain types of cancer cells through estrogenic effects. Cadmium also activates mitogen-activated protein kinases, including MAPK1, MAPK3, MAPK8, and MAPK9, among six other proteins, which causes cell apoptosis. Other recorded protein targets include amyloid-beta precursor protein (APP), ferritin light chain (FTL), metallothionein-1A (MT1A), and metallothionein-2 (MT2A).

Toxicity Profile
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 molecular weight 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. (7, 1, 2, 3)
Carcinogenicity (IARC Classification)1, carcinogenic to humans. (10)
Minimum Risk LevelAcute Inhalation: 0.00003 mg/m3 (9) Chronic Inhalation: 0.00001 mg/m3 (9) Intermediate Oral: 0.0005 mg/kg/day (9) Chronic Oral: 0.0001 mg/kg/day (9)
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. (6)
TreatmentCadmium poisoning is treated by removal from exposure and supportive care. If ingested, induced vomiting or gastric lavage may be performed. (11)
