代谢
砷主要通过吸入或摄入进入人体,其次是皮肤接触。进入人体后,砷会在全身分布,根据需要被还原成亚砷酸盐,然后通过亚砷酸盐甲基转移酶被甲基化成单甲基砷(MMA)和二甲基硅酸(DMA)。砷及其代谢物主要通过尿液排出体外。已知砷能诱导金属结合蛋白金属硫蛋白,通过结合砷和其他金属并使其生物活性失效,以及作为抗氧化剂的作用,从而减少砷和其他金属的毒性效应。
Arsenic is absorbed mainly by inhalation or ingestion, as to a lesser extent, dermal exposure. It is then distributed throughout the body, where it is reduced into arsenite if necessary, then methylated into monomethylarsenic (MMA) and dimethylarsenic acid (DMA) by arsenite methyltransferase. Arsenic and its metabolites are primarily excreted in the urine. Arsenic is known to induce the metal-binding protein metallothionein, which decreases the toxic effects of arsenic and other metals by binding them and making them biologically inactive, as well as acting as an antioxidant.

毒理性
  • 毒性总结
砷及其代谢物通过多种机制干扰ATP的产生。在柠檬酸循环层面,砷抑制了丙酮酸脱氢酶,并通过与磷酸竞争,解偶联氧化磷酸化,从而抑制了与能量相关的NAD+的还原、线粒体呼吸和ATP的合成。过氧化氢的产生也增加了,这可能会形成活性氧物种和氧化应激。砷的致癌性受到砷与微管蛋白结合的影响,这会导致非整倍体、多倍体和有丝分裂的停滞。其他砷蛋白靶点的结合也可能导致DNA修复酶活性改变、DNA甲基化模式改变和细胞增殖。
Arsenic and its metabolites disrupt ATP production through several mechanisms. At the level of the citric acid cycle, arsenic inhibits pyruvate dehydrogenase and by competing with phosphate it uncouples oxidative phosphorylation, thus inhibiting energy-linked reduction of NAD+, mitochondrial respiration, and ATP synthesis. Hydrogen peroxide production is also increased, which might form reactive oxygen species and oxidative stress. Arsenic's carginogenicity is influenced by the arsenical binding of tubulin, which results in aneuploidy, polyploidy and mitotic arrests. The binding of other arsenic protein targets may also cause altered DNA repair enzyme activity, altered DNA methylation patterns and cell proliferation. (T1, A17)

  • 健康影响
砒霜中毒可能导致多系统器官衰竭而死亡,可能是由于细胞坏死而非凋亡。砒霜也是一种已知的致癌物,尤其是在皮肤癌、肝癌、膀胱癌和肺癌中。
Arsenic poisoning can lead to death from multi-system organ failure, probably from necrotic cell death, not apoptosis. Arsenic is also a known carcinogen, esepcially in skin, liver, bladder and lung cancers. (T1, L20)
