代谢

钴通过肺部、胃肠系统和皮肤被吸收。由于它是维生素B12（氰钴胺）的一个组成部分，因此它被分布到身体的大部分组织中。它在血液中运输，通常与白蛋白结合，肝脏和肾脏中的含量最高。钴主要通过尿液和粪便排出。

Cobalt is absorbed though the lungs, gastrointestinal tract, and skin. Since it is a component of the vitamin B12 (cyanocobalamin), it is distributed to most tissues of the body. It is transported in the blood, often bound to albumin, with the highest levels being found in the liver and kidney. Cobalt is excreted mainly in the urine and faeces. (L29)

毒理性

• 毒性总结

钴被认为通过氧化剂和自由基反应过程表现出其毒性。它能产生氧自由基，并且可能被氧化成离子态的钴，导致脂质过氧化增加、DNA损伤，并诱导某些酶，从而导致细胞凋亡。�alt还被证明能阻断无机钙通道，可能影响神经递质的传递。钴还能与硫辛酸螯合，影响丙酮酸或脂肪酸的氧化。此外，钴可能通过干扰锌指DNA修复蛋白来抑制DNA修复，还显示出能抑制血红素合成和葡萄糖代谢。钴可能激活特定的辅助T淋巴细胞，并直接与免疫蛋白相互作用，如抗体（IgA和IgE）或Fc受体，导致免疫致敏。

Cobalt is believed to exhibit its toxicity through a oxidant-based and free radical-based processes. It produces oxygen radicals and may be oxidized to ionic cobalt, causing increased lipid peroxidation, DNA damage, and inducing certain enzymes that lead to cell apoptosis. Cobalt has also been shown to block inorganic calcium channels, possibly impairing neurotransmission. Cobalt can also chelate lipoic acids, impairing oxidation of pyruvate or fatty acids. In addition, cobalt may inhibit DNA repair by interacting with zinc finger DNA repair proteins, and has also been shown to inhibit heme synthesis and glucose metabolism. Cobalt may activate specific helper T-lymphocyte cells and interact directly with immunologic proteins, such as antibodies (IgA and IgE) or Fc receptors, resulting in immunosensitization. (L29)

• 致癌性证据

钴和钴化合物在人类中的致癌性证据不足。有充分证据表明钴金属粉末在实验动物中具有致癌性。有限证据显示含有钴、铬和钼的金属合金在实验动物中具有致癌性。总体评估：钴和钴化合物可能对人类具有致癌性（2B组）。/钴和钴化合物/

There is inadequate evidence for the carcinogenicity of cobalt and cobalt compounds in humans. There is sufficient evidence for the carcinogenicity of cobalt metal powder in experimental animals. There is limited evidence for the carcinogenicity of metal alloys containing cobalt, chromium and molybdenum in experimental animals. ... Overall Evaluation: Cobalt and cobalt compounds are possibly carcinogenic to humans (Group 2B). /Cobalt and cobalt compounds/
