毒性机制
Palladium ions are able to inhibit most major cellular fuctions. They form strong complexes with both inorganic and organic ligands, substitute essential ions, bind to amino acids and various enzymes including creatine kinase and prolyl hydroxylase, and interact with functional groups of other macromolecules such as DNA leading to strand breakage. (L798)
代谢
Palladium may be absorbed through oral, dermal, and inhalation exposure. Once in the body it distributes to the kidney, liver, spleen, lymph nodes, adrenal gland, lung and bone. Palladium and its metabolites are excreted in the urine and faeces. (A21)
致癌性
No indication of carcinogenicity to humans (not listed by IARC).
用途/来源
Palladium is found mainly in catalytic converters and jewelry. It is also found in many electronics including computers, mobile phones, multi-layer ceramic capacitors, component plating, low voltage electrical contacts, and SED/OLED/LCD televisions. Palladium is also used in dentistry, medicine, hydrogen purification, chemical applications, and groundwater treatment. Palladium plays a key role in the technology used for fuel cells, which combines hydrogen and oxygen to produce electricity, heat and water. (L794)
健康影响
Contact with palladium may cause palladium sensitivity and allergy. Animal studies have shown that palladium may damage the liver and kidney. (L798)
症状
Skin contact with palladium may cause contact dermatitis, erythema, and oedema. (L798)
