代谢

汞主要通过摄入和吸入被吸收，然后通过血液流布全身，其中一部分会与血红蛋白上的巯基团结合。汞可以经过氧化转化为汞离子，这一过程通过过氧化氢酶-过氧化氢途径进行。汞原子能够扩散进入过氧化氢酶酶裂隙，到达含有血红素环的活性位点。由于过氧化氢酶-过氧化氢途径普遍存在，氧化最可能在所有组织中发生。氧化后，汞倾向于在肾脏中积累。汞主要通过呼出和粪便排出体外。(A6, L7)

Mercury is absorbed mainly via ingestion and inhalation, then distributed throughout the body via the bloodstream, where a portion binds to sulfhydryl groups on haemoglobin. Mercury can undergo oxidation to mercuric mercury, which takes place via the catalase-hydrogen peroxide pathway. The mercury atom is able to diffuse down the cleft in the catalase enzyme to reach the active site where the heme ring is located. Oxidation most likely occurs in all tissue, as the catalase hydrogen peroxide pathway is ubiquitous. Following oxidation, mercury tends to accumulate in the kidneys. Mercury is excreted mainly by exhalation and in the faeces. (A6, L7)

• 毒性总结

汞离子与蛋白质的巯基或硫醇基团的高亲和力结合被认为是汞活性的主要机制。通过改变细胞内巯基状态，汞可以促进氧化应激、脂质过氧化、线粒体功能障碍和血红素代谢的变化。已知汞能与微囊和线粒体酶结合，导致细胞损伤和死亡。例如，汞能抑制水通道蛋白，阻止细胞膜上的水流。它还抑制LCK蛋白，导致T细胞信号传导减少和免疫系统抑制。汞还被认为是通过作用于突触后神经细胞膜来抑制神经兴奋性。它还通过抑制蛋白激酶C和碱性磷酸酶来影响神经系统，这会损害大脑微血管的形成和功能，并改变血脑屏障。汞还能产生自身免疫反应，可能是通过修饰主要组织相容性复合体（MHC）II类分子、自身肽、T细胞受体或细胞表面粘附分子。

High-affinity binding of the divalent mercuric ion to thiol or sulfhydryl groups of proteins is believed to be the major mechanism for the activity of mercury. Through alterations in intracellular thiol status, mercury can promote oxidative stress, lipid peroxidation, mitochondrial dysfunction, and changes in heme metabolism. Mercury is known to bind to microsomal and mitochondrial enzymes, resulting in cell injury and death. For example, mercury is known to inhibit aquaporins, halting water flow across the cell membrane. It also inhibits the protein LCK, which causes decreased T-cell signalling and immune system depression. Mercury is also believed to inhibit neuronal excitability by acting on the postsynaptic neuronal membrane. It also affects the nervous system by inhibiting protein kinase C and alkaline phosphatase, which impairs brain microvascular formation and function, as well as alters the blood-brain barrier. Mercury also produces an autoimmune response, likely by modification of major histocompatibility complex (MHC) class II molecules, self peptides, T-cell receptors, or cell-surface adhesion molecules.

• 健康影响

水银主要影响神经系统。接触高水平的金属汞、无机汞或有机汞可能导致大脑、肾脏和发育中的胎儿永久性损害。对大脑功能的影响可能导致易怒、害羞、震颤、视力或听力改变以及记忆问题。儿童的水银中毒，即手足粉红病，特点是手和脚疼痛和粉红色变色。水银中毒还可能引起亨特-拉塞尔综合症和熊本病。

Mercury mainly affects the nervous system. Exposure to high levels of metallic, inorganic, or organic mercury can permanently damage the brain, kidneys, and developing fetus. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems. Acrodynia, a type of mercury poisoning in children, is characterized by pain and pink discoloration of the hands and feet. Mercury poisoning can also cause Hunter-Russell syndrome and Minamata disease. (L7)

  Vibrational population dynamics of the HgI photofragment in ethanol solution

  摘要：

  The vibrational population dynamics of HgI fragments in ethanol solution, resulting from the 320 nm photolysis of HgI2, are examined both experimentally and by a simulation. The experiments reveal an HgI population distribution which rapidly relaxes toward equilibrium. At the earliest times, the HgI exhibits vibrational coherent wave-packet motion that dephases with a time constant of ca. 1 ps. These data are used to gain insight into the character of the solvated potential energy curves. The population relaxation was adequately reproduced by master equations which were formulated to incorporate the HgI anharmonicity and a solvent frequency dependent friction. This treatment characterizes the spontaneous vibrational relaxation timescale for the n″=1→0 transition to be ca. 3 ps, and is used to identify the relaxation rate constants for all other HgI level pairs. The simulations estimate that the initial excess energy of HgI is centered at n″≂10 which corresponds to a total excess energy of ca. 1050 cm−1.

• Structural diversity in mercury(II) coordination complexes with asymmetrical hydrazone-based ligands derived from pyridine
  作者：Asad Masoumi、Masoumeh Servati Gargari、Ghodrat Mahmoudi、Barbara Miroslaw、Bruno Therrien、Marjan Abedi、Paul Hazendonk

  DOI：10.1016/j.molstruc.2015.02.016

  日期：2015.5

  Three novel Hg(II) complexes 1-3 of asymmetrical hydrazone-pyridine based ligands, L-1-L-3, with distinct coordination structures have been prepared and characterized by a single crystal X-ray diffraction, elemental and thermal analysis, and IR spectroscopy. The complexes form either discrete units with one (1) or two (2) organic ligands, or one-dimensional polymers (3). Hence the ligands can be regarded as chelating (1), mono-dentate (2) or bridging (3) agents. The mercury center is essentially neutralized in each complex by two iodide anions. The coordination in complexes 2 and 3 adopts deformed tetrahedral shapes. In contrast the Hg(II) cation in complex 1 binds three coplanar ligating atoms (O,N,N) and, as with pincer ligands, its coordination polyhedron is supplemented with two I- anions in apical positions. The structural diversity in these complexes is strongly influenced by the position of N atom in pyridine derived moieties. The crystal structure is stabilized by N/O-H center dot center dot center dot N/O/I hydrogen bonds and pi center dot center dot center dot pi interactions. (C) 2015 Elsevier B.V. All rights reserved.
