代谢
铬通过口服、吸入或皮肤接触被吸收,并分布到几乎所有组织中,肾脏和肝脏中的浓度最高。骨骼也是一个主要的储存场所,并可能导致长期保留。六价铬与硫酸盐和铬酸盐的相似性使其能够通过硫酸盐转运机制进入细胞。在细胞内,六价铬首先被还原为五价铬,然后通过许多物质,包括抗坏血酸、谷胱甘肽和烟酸腺嘌呤二核苷酸,被还原为三价铬。铬几乎全部通过尿液排出体外。(A12, L16)
Chromium is absorbed from oral, inhalation, or dermal exposure and distributes to nearly all tissues, with the highest concentrations found in kidney and liver. Bone is also a major storage site and may contribute to long-term retention. Hexavalent chromium's similarity to sulfate and chromate allow it to be transported into cells via sulfate transport mechanisms. Inside the cell, hexavalent chromium is reduced first to pentavalent chromium, then to trivalent chromium by many substances including ascorbate, glutathione, and nicotinamide adenine dinucleotide. Chromium is almost entirely excreted with the urine. (A12, L16)

毒理性
  • 毒性总结
三价铬还可以与肽、蛋白质和DNA形成配合物,导致DNA-蛋白质交联、DNA链断裂、DNA-DNA链间交联、铬-DNA加合物、染色体畸变以及细胞信号通路的变化。研究表明,三价铬通过过度刺激细胞调控通路和通过激活某些丝裂原活化蛋白激酶来增加过氧化物的水平,从而诱导癌变。它还可以通过将组蛋白去乙酰化酶1-DNA甲基转移酶1复合物与CYP1A1启动子染色质交联,抑制组蛋白修饰,从而引起转录抑制。铬可能通过修饰金属调控转录因子1,导致抑制锌诱导的金属硫蛋白转录,从而增加其自身的毒性。(A12, L16, A34, A35, A36)
Trivalent chromium may also form complexes with peptides, proteins, and DNA, resulting in DNA-protein crosslinks, DNA strand breaks, DNA-DNA interstrand crosslinks, chromium-DNA adducts, chromosomal aberrations and alterations in cellular signaling pathways. It has been shown to induce carcinogenesis by overstimulating cellular regulatory pathways and increasing peroxide levels by activating certain mitogen-activated protein kinases. It can also cause transcriptional repression by cross-linking histone deacetylase 1-DNA methyltransferase 1 complexes to CYP1A1 promoter chromatin, inhibiting histone modification. Chromium may increase its own toxicity by modifying metal regulatory transcription factor 1, causing the inhibition of zinc-induced metallothionein transcription. (A12, L16, A34, A35, A36)

  • 健康影响
三价铬的毒性不高。它可能被氧化成六价铬,这是一种已知的致癌物质。六价铬还被证明会影响生殖和发育。(A12)
Chromium in its trivalent state is not very toxic. It may be oxidized to hexavalent chromium, a known carcinogen. Hexavalent chromium has also been shown to affect reproduction and development. (A12)

毒理性
  • 症状
三价铬不具高毒性,但它可能被氧化为六价铬。吸入六价铬可能会刺激鼻粘膜,导致鼻溃疡、流鼻涕以及呼吸问题,如哮喘、咳嗽、气短或喘鸣。摄入六价铬会在胃和小肠造成刺激和溃疡,并可能导致贫血。皮肤接触可能导致皮肤溃疡。
Chromium in its trivalent state is not very toxic, but it may be oxidized to hexavalent chromium. Breathing hexavalent chromium can cause irritation to the lining of the nose, nose ulcers, runny nose, and breathing problems, such as asthma, cough, shortness of breath, or wheezing. Ingestion of hexavalent chromium causes irritation and ulcers in the stomach and small intestine, as well as anemia. Skin contact can cause skin ulcers. (L16)

  • Reactions of laser-ablated chromium atoms with dioxygen. Infrared spectra of CrO, OCrO, CrOO, CrO3, Cr(OO)2, Cr2O2, Cr2O3 and Cr2O4 in solid argon

    日期:1997.8.22
    Reactions of laser-ablated Cr atoms with O2 gave a very strong, sharp 965.4 cm−1 band and weak, sharp 1869.7, 984.3, 914.4, 846.3, 716.2, and 643.1 cm−1 bands. The 1869.7, 965.4, and 914.4 cm−1 bands track together on annealing, show 52Cr, 53Cr, 54Cr isotopic splittings appropriate for a single Cr atom and triplets with statistical 16,18O2 for two equivalent O atoms, and are assigned to the ν1+ν3, ν3 and ν1 modes of the bent (128°±4°) chromium dioxide OCrO molecule. The 984.3 cm−1 band shows chromium isotopic splittings for two Cr atoms and 16,18O2 components for two O atoms, and is attributed to the bent CrOCrO molecule. The weak 846.3 cm−1 band exhibits proper oxygen isotopic behavior for CrO and is redshifted 39 cm−1 from the gas-phase value, the maximum shift observed for a first row transition metal monoxide. The sharp 716.2 and 643.1 cm−1 bands track together; the former reveals Cr isotopic splittings for two Cr atoms and the latter 16,18O2 splittings for two sets of dioxygen subunits; the branched-puckered-ring dimer O(Cr2O2)O is identified. Annealing produces new bands due to CrOO, CrO3, Cr(OO)2 and the ring dimers (Cr2O2) and (Cr2O2)O, which are identified from isotopic shifts and splitting patterns.
