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多数组织中。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)

  • 毒性总结
钴被认为通过氧化剂和自由基过程表现出其毒性。它产生氧自由基,并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,导致细胞凋亡。钴还被证明可以阻断无机钙通道,可能损害神经传递。钴还可以与硫辛酸螯合,损害丙酮酸或脂肪酸的氧化。此外,钴可能通过与锌指DNA修复蛋白相互作用来抑制DNA修复,并且已被证明可以抑制血红素合成和葡萄糖代谢。钴可能激活特定的辅助性T淋巴细胞,并直接与免疫蛋白(如抗体IgA和IgE或Fc受体)相互作用,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)

钴的代谢和毒理学概述。根据最近对钴干扰几乎所有动物细胞感知缺氧(低氧)的研究,更新了钴的生物功能。钴(Co(2+))稳定了转录激活因子低氧诱导因子(HIF),从而模拟低氧并刺激促红细胞生成素(Epo)的产生,但可能也是通过相同的机制诱导了一系列对低氧适应性反应的协调上调,其中许多具有潜在的致癌效应。另一方面,这意味着钴(Co(2+))在组织低氧条件下可能具有有益效果,并且可能代表低氧预处理的一种替代方法。钴在大剂量时具有急性毒性,在哺乳动物体外测试系统中,钴离子和钴金属具有细胞毒性,可诱导凋亡,在高浓度时引起坏死和炎症反应。钴金属和盐也具有基因毒性,主要由活性氧种类引起的氧化DNA损伤引起,可能还与DNA修复抑制有关。值得注意的是,钴金属和硫酸钴对实验动物具有足够证据的致癌性,但对人类尚不足够。有趣的是,钴(Co(2+))的一些毒性效应最近被认为可能是由于假定的钙(Ca(2+))进入和Ca(2+)-信号传导的抑制作用以及与Ca(2+)竞争细胞内Ca(2+)-结合蛋白所致。钴(Co(2+))的组织分配及其在单次给药后随时间的变化已在人类中进行了研究,但主要是在实验动物中。钴主要积累在肝脏、肾脏、胰腺和心脏中,给药后随着时间的推移,骨骼和骨骼肌的相对含量增加。在人类中,肾排泄最初是迅速的,但在最初几天内逐渐减少,随后是持续数周的第二个缓慢阶段,并且在数年内显著长期保留在组织中。在血清中,钴(Co(2+))与白蛋白结合,自由离子Co(2+)的浓度估计为总钴浓度的5-12%。在人红细胞中,钴(Co(2+))的膜传输途径似乎与钙(Ca(2+))共享,但由于钴在细胞质中有效结合并且不被Ca泵排出,因此钴的摄入本质上是不可逆的。诱人推测这也许在其他动物细胞中也可能发生。如果是这种情况,钴在细胞和组织中的组织分配和生物动力学将与钙的摄入密切相关,钴主要分配到钙转换率高的组织中,并在细胞转换率慢的组织中积累和保留。职业钴暴露,例如在钴加工厂和硬质金属工业中,是众所周知的,并且在最近几年由于工作场所卫生条件的改善而有所减少。然而,值得注意的是,最近在接近或略低于当前职业暴露限值以下的钴暴露后,已经证明了对心脏和肺的不良反应。在过去的几十年中,钴-铬硬质金属合金在骨科关节置换术中的应用,特别是在髋关节置换术中的金属对金属轴承,创造了一个全新的内部钴暴露源。腐蚀和磨损产生可溶性金属离子和以数十亿纳米尺寸磨损颗粒形式存在的金属碎片,通过淋巴和系统血管系统全身传播。这可能导致假体周围软组织的局部不良反应,并引起全身毒性。值得注意的是,金属纳米颗粒已被证明比更大的微米尺寸颗粒更具毒性,这使得纳米毒理学成为一个关键的新学科。作为钴暴露的另一个潜在来源,有人怀疑运动员可能滥用钴盐作为增加有氧性能的Epo兴奋剂的诱人替代品。体外钴的毒性主要存在于离子化钴中。诱人推测离子化钴也是体内全身毒性的主要形式。根据这一假设,风险评估的相关参数是全身钴离子暴露的时间平均价值,从理论角度来看,可以通过测量红细胞中的钴含量来获得,因为它们的钴摄入仅反映自由离子化钴(Co(2+))的摄入,并且在它们120天的寿命期间摄入实际上是不可逆的。这显然需要未来在暴露个体中进行临床研究,系统地比较红细胞和血清中钴浓度的同时测量。
Cobalt metabolism and toxicology are summarized. The biological functions of cobalt are updated in the light of recent understanding of cobalt interference with the sensing in almost all animal cells of oxygen deficiency (hypoxia). Cobalt (Co(2+)) stabilizes the transcriptional activator hypoxia-inducible factor (HIF) and thus mimics hypoxia and stimulates erythropoietin (Epo) production, but probably also by the same mechanism induces a coordinated up-regulation of a number of adaptive responses to hypoxia, many with potential carcinogenic effects. This means on the other hand that cobalt (Co(2+)) also may have beneficial effects under conditions of tissue hypoxia, and possibly can represent an alternative to hypoxic preconditioning. Cobalt is acutely toxic in larger doses, and in mammalian in vitro test systems cobalt ions and cobalt metal are cytotoxic and induce apoptosis and at higher concentrations necrosis with inflammatory response. Cobalt metal and salts are also genotoxic, mainly caused by oxidative DNA damage by reactive oxygen species, perhaps combined with inhibition of DNA repair. Of note, the evidence for carcinogenicity of cobalt metal and cobalt sulfate is considered sufficient in experimental animals, but is as yet considered inadequate in humans. Interestingly, some of the toxic effects of cobalt (Co(2+)) have recently been proposed to be due to putative inhibition of Ca(2+) entry and Ca(2+)-signaling and competition with Ca(2+) for intracellular Ca(2+)-binding proteins. The tissue partitioning of cobalt (Co(2+)) and its time-dependence after administration of a single dose have been studied in man, but mainly in laboratory animals. Cobalt is accumulated primarily in liver, kidney, pancreas, and heart, with the relative content in skeleton and skeletal muscle increasing with time after cobalt administration. In man the renal excretion is initially rapid but decreasing over the first days, followed by a second, slow phase lasting several weeks, and with a significant long-term retention in tissues for several years. In serum cobalt (Co(2+)) binds to albumin, and the concentration of free, ionized Co(2+) is estimated at 5-12% of the total cobalt concentration. In human red cells the membrane transport pathway for cobalt (Co(2+)) uptake appears to be shared with calcium (Ca(2+)), but with the uptake being essentially irreversible as cobalt is effectively bound in the cytosol and is not itself extruded by the Ca-pump. It is tempting to speculate that this could perhaps also be the case in other animal cells. If this were actually the case, the tissue partitioning and biokinetics of cobalt in cells and tissues would be closely related to the uptake of calcium, with cobalt partitioning primarily into tissues with a high calcium turn-over, and with cobalt accumulation and retention in tissues with a slow turn-over of the cells. The occupational cobalt exposure, e.g. in cobalt processing plants and hard-metal industry is well known and has probably been somewhat reduced in more recent years due to improved work place hygiene. Of note, however, adverse reactions to heart and lung have recently been demonstrated following cobalt exposure near or slightly under the current occupational exposure limit. Over the last decades the use of cobalt-chromium hard-metal alloys in orthopedic joint replacements, in particular in metal-on-metal bearings in hip joint arthroplasty, has created an entirely new source of internal cobalt exposure. Corrosion and wear produce soluble metal ions and metal debris in the form of huge numbers of wear particles in nanometric size, with systemic dissemination through lymph and systemic vascular system. This may cause adverse local reactions in peri-prosthetic soft-tissues, and in addition systemic toxicity. Of note, the metal nanoparticles have been demonstrated to be clearly more toxic than larger, micrometer-sized particles, and this has made the concept of nanotoxicology a crucial, new discipline. As another new potential source of cobalt exposure, suspicion has been raised that cobalt salts may be misused by athletes as an attractive alternative to Epo doping for enhancing aerobic performance. The cobalt toxicity in vitro seems to reside mainly with ionized cobalt. It is tempting to speculate that ionized cobalt is also the primary toxic form for systemic toxicity in vivo. Under this assumption, the relevant parameter for risk assessment would be the time-averaged value for systemic cobalt ion exposure that from a theoretical point of view might be obtained by measuring the cobalt content in red cells, since their cobalt uptake reflects uptake only of free ionized cobalt (Co(2+)), and since the uptake during their 120 days life span is practically irreversible. This clearly calls for future clinical studies in exposed individuals with a systematic comparison of concurrent measurements of cobalt concentration in red cells and in serum.

    Co,Ni和Cu电沉积过程中扩散层内部的磁场引起的微对流现象
    摘要:
    Co,Ni和Cu在高达B的外部均匀磁场中的恒电位电沉积 对与电极表面不同排列的= 1 T进行了研究。关于梯度力讨论了扩散层内部的对流效应。梯度力的强度取决于金属离子的顺磁化率,扩散层内部的浓度梯度以及磁场的强度和梯度。对于铜的沉积,最大的梯度力在沉积过程开始时起作用,并且在几秒钟后下降到可以忽略的值,尽管磁化率比Ni和Co低。但是没有发生氢反应。对于钴的沉积,由于主要的析氢反应,梯度力在开始时较低,并且在约10 s的沉积时间后达到最大。Ni的沉积是混合控制的,并通过析氢反应进行叠加。梯度力对沉积行为的影响很小。已经表明,梯度力作用在最高浓度梯度的区域中的电极表面附近。假设扩散层内部的微磁对流(MMC效应)可以通过磁流体动对流(MHD)消除。

    are present ΔG‡ falls to 54.5 ± 0.5 kJ mol–1. Complexes of the crown ether dithiocarbamates with Ni, Cu, Cr, Fe, Co, and Mo have been prepared and their electrochemistry investigated. Small shifts in the values of E½ were observed in the presence of alkali-metal cations. The molecular structure of cobalt tris[(aza-15-crown-5)dithiocarbamate] has been determined by X-ray crystallography.
