代谢
最近,碲(Te)、锑(Sb)和锗(Ge)已被用作相变光磁性磁盘的合金,例如数字多功能磁盘-随机存取存储器(DVD-RAM)和可记录的DVD光盘(DVD-RW)。尽管这些所谓的“奇异”元素被认为是非必需且有害的,但关于它们的毒性效应和新陈代谢知之甚少。将碲化合物、锑化合物和二氧化锗同时给予大鼠。通过物种分析确定了它们的代谢物分布并进行了鉴定。Te和Sb在红细胞(RBCs)中积累:Te以二甲基硅形式在红细胞中积累,而Sb以无机/非甲基化形式积累。此外,三甲基硒(TMTe)是Te的尿液代谢物,而尿液中的Sb没有甲基化,但被氧化。Ge在大鼠中也没有甲基化。这些结果表明,每种半金属都通过独特的途径进行代谢。/锑代谢物/
Recently, tellurium (Te), antimony (Sb) and germanium (Ge) have been used as an alloy in phase-change optical magnetic disks, such as digital versatile disk-random access memory (DVD-RAM) and DVD-recordable disk (DVD-RW). Although these metalloids, the so-called "exotic" elements, are known to be non-essential and harmful, little is known about their toxic effects and metabolism. Metalloid compounds, tellurite, antimonite and germanium dioxide, were simultaneously administered to rats. Their distributions metabolites were determined and identified by speciation. Te and Sb accumulated in red blood cells (RBCs): Te accumulated in RBCs in the dimethylated form, while Sb accumulated in the inorganic/non-methylated form. In addition, trimethyltelluronium (TMTe) was the urinary metabolite of Te, whereas Sb in urine was not methylated but oxidized. Ge was also not methylated in rats. These results suggest that each metalloid is metabolized via a unique pathway. /Antimony metabolites/

毒理性
  • 毒性总结
锑是一种银白色、有光泽、硬而脆的金属。商业级锑广泛应用于合金中,其百分比从1%到20%不等。它大大提高了铅的硬度和机械强度。电池、减摩合金、印刷合金、小型武器和追踪子弹、电缆护套以及一些小产品大约使用了生产出来的一半金属。另一半是化合物,包括氧化物、硫化物、钠锑酸盐和三氯化锑。16世纪欧洲的医生和炼金术倡导者帕拉塞尔苏斯偏爱使用金属,包括锑,作为药物。大约1560-1660年的时期被称为“锑之战”,反映了在医学上盖伦医学和帕拉塞尔苏斯实践之间的冲突。人类研究:工厂工人吸入含有锑的尘埃会引起胃肠道刺激,这可能是锑尘埃通过粘膜纤毛电梯运输并吞咽的结果。急性症状,包括腹部绞痛、腹泻和呕吐,在暴露于大量锑烟的熔炉工人中有所报道。长期暴露于空气中的锑的工人可能会出现持续的症状,如皮炎、眼部刺激、阻塞性肺改变和肺气肿,并伴有增加的肺尘病。长期接触锑的皮肤效应已有报道。慢性接触锑的工人偶尔会出现痒性皮肤丘疹,进展为皮疹,被称为“锑斑”。在一座锑金属冶炼厂工作的妇女与一组未接触锑的类似妇女进行了比较。暴露组自发性流产的发生率更高(12.5%对4.1%),早产(3.4%对1.2%)和妇科问题(77.5%对56%)。动物研究:给予含有0.5-2%锑的饮食的大鼠体重增加减少,血清中一种肝脏酶,天冬氨酸转氨酶的水平升高。每隔一天给兔子喂食5至55毫克金属锑,持续30、60和90天,流产频繁。锑在细菌或噬菌体中具有诱变性。它被证明能诱导动物或植物细胞的染色体畸变或异常细胞分裂。
IDENTIFICATION AND USE: Antimony is a silver-white, lustrous, hard, brittle metal. Commercial-grade antimony is widely used in alloys with percentages ranging from 1 to 20. It greatly increases the hardness and mechanical strength of lead. Batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing, and minor products use about half the metal produced. Compounds taking up the other half are oxides, sulfides, sodium antimonate, and antimony trichloride. Paracelsus, a physician and proponent of alchemy in sixteen century Europe favored the use of metals, including antimony, as drugs. The period of c. 1560-1660 was termed the 'antimony war' and reflects the conflict in medicine between Galenic medicine and the practices of Paracelsus. HUMAN STUDIES: Inhalation of dust containing antimony by factory workers induced gastrointestinal irritation, probably result of antimony dust transported via the mucociliary escalator and swallowed. Acute symptoms, including abdominal cramps, diarrhea, and vomiting among smelter workers subjected to heavy exposure to antimony fumes were reported. Workers chronically exposed to airborne antimony can develop persistent symptoms such as dermatitis, eye irritation, obstructive lung alterations, and emphysema with increased pneumoconiosis. Skin effects from chronic antimony exposures have been reported. Pruritic skin papules progressing to skin eruptions, referred as "antimony spots", are occasionally seen in workers chronically exposed to antimony. Women working in an antimony metallurgical plant were compared to a similar group of women not exposed to antimony. The exposed group had higher incidences of spontaneous abortions (12.5 vs 4.1%), premature births (3.4 vs 1.2%), and gynecological problems (77.5 vs 56%). ANIMAL STUDIES: Rats given a diet containing 0.5-2% antimony had decreased weight gain, and had elevated serum levels of a liver enzyme, aspartate aminotransferase. Abortions were frequent in rabbits fed doses of metallic antimony of 5 to 55 mg every other day for 30, 60, and 90 days. Antimony was mutagenic in bacteria or phage. It was shown to induce chromosomal aberrations or abnormal cell divisions in animal or plant cells.

对小鼠吸入在不同温度下形成的颗粒后,标记锑的保留模式进行了研究。较低温度的气溶胶更易溶解并且迅速离开肺部,集中在骨骼中。而在较高温度下产生的两种气溶胶导致(124)锑在肺部保留的时间延长。
A study of the retention patterns of labeled antimony in mice following inhalation of particles formed at different temp was conducted. The lower temp aerosol was more sol & left the lung rapidly, localizing in the skeleton. The 2 aerosols produced at higher temp resulted in (124)antimony remaining in the lung for extended periods.

砷和锑是有毒的类金属,它们在环境中自然存在,所有生物体都发展出了解毒它们的途径。真核生物中最有效的类金属耐受系统包括下调类金属的摄取、从细胞外排泌,以及与植物螯合素或谷胱甘肽结合形成复合物,随后将其隔离到液泡中。由于砷基药物在治疗某些类型的癌症和由原生动物寄生虫引起的疾病中的使用越来越多,以及为了开发生物和植物修复策略以治理类金属污染地区,理解砷和锑的运输系统具有重要意义。然而,与原核生物相比,长期以来关于砷和锑特定运输蛋白以及真核生物中类金属运输机制的知识非常有限。在这里,我们回顾了最近在理解真核生物中砷和锑运输途径方面的进展,包括水甘油通道蛋白在类金属摄取和排泌中的双重作用,酵母Acr3转运蛋白介导的砷运输机制及其在蕨类植物中砷超积累的作用,植物中砷-植物螯合素复合物的液泡转运蛋白的鉴定,以及哺乳动物ABC转运蛋白识别的砷底物形式。/锑/
Arsenic and antimony are toxic metalloids, naturally present in the environment and all organisms have developed pathways for their detoxification. The most effective metalloid tolerance systems in eukaryotes include downregulation of metalloid uptake, efflux out of the cell, and complexation with phytochelatin or glutathione followed by sequestration into the vacuole. Understanding of arsenic and antimony transport system is of high importance due to the increasing usage of arsenic-based drugs in the treatment of certain types of cancer and diseases caused by protozoan parasites as well as for the development of bio- and phytoremediation strategies for metalloid polluted areas. However, in contrast to prokaryotes, the knowledge about specific transporters of arsenic and antimony and the mechanisms of metalloid transport in eukaryotes has been very limited for a long time. Here, we review the recent advances in understanding of arsenic and antimony transport pathways in eukaryotes, including a dual role of aquaglyceroporins in uptake and efflux of metalloids, elucidation of arsenic transport mechanism by the yeast Acr3 transporter and its role in arsenic hyperaccumulation in ferns, identification of vacuolar transporters of arsenic-phytochelatin complexes in plants and forms of arsenic substrates recognized by mammalian ABC transporters. /Antimony/

2.对环境的影响:

一、健康危害 侵入途径:吸入、食入。 健康危害:锑对粘膜有刺激作用,可引起内脏损害。 急性中毒:接触较高浓度引起化学性结膜炎、鼻炎、咽炎、喉炎、支气管炎、肺炎。口服引起急性胃肠炎。全身症状有疲乏无力、头晕、头痛、四肢肌肉酸痛。可引起心、肝、肾损害。 慢性影响:常出现头痛、头晕、易兴奋、失眠、乏力、胃肠功能紊乱、粘膜刺激症状。可引起鼻中隔穿孔;在锑冶炼过程中可引起锑尘肺;对皮肤有明显的刺激作用和致敏作用。

二、毒理学资料及环境行为

急性毒性:LD507000mg/kg(大鼠经口) 锑以+3、+4、+5价化合物存在于环境中,尤以三价化合物为常见,主要的有三硫化二锑、三氧化二锑、三氯化锑等。

迁移转化:天然水中锑的自然含量一般为0.01~5.0ppb,平均为0.5ppb。海水中含锑量为0.18~5.6ppb,平均为0.24ppb。锑在水中的迁移机制,有通过结晶矿物的迁移,有机螯合迁移、被吸附性离子迁移、与氧化物相缔合的迁移,以及可溶性迁移。溶于水中的锑化合物有三氯化锑、硫酸锑、酒石酸锑和五氯化锑。锑在淡水中以五价锑存在。海水中的锑以络合物形式存在,其主要配位体是羟基,下不为例上的形态为Sb(OH)6-或二聚物Sb2O(OH)4。受锑污染的土壤,锑一般富集在表层,主要是土壤表层无机和有机胶体的吸附作用。锑在土壤中是以+3、+5价状态存在。在旱田或干土中,土壤处于氧化状态,此时土壤中的Sb3+可氧化成Sb5+,锑以Sb5+存在居多。水田土壤处于淹没还原状态,土壤中的锑主要以Sb3+存在。

危险特性:遇明火、高热可燃。粉体与空气可形成爆炸性混合物,当达到一定的浓度时,遇火星会发生爆炸。与硝酸铵、二氟化溴、三氮化溴、氯酸、氧化氯、三氟化氯、硝酸、硝酸钾、高锰酸钾、过氧化钾接触能引起反应。 燃烧(分解)产物:氧化锑。

制备方法与用途

化学性质
有光泽的银白色金属(六方晶系或菱面体晶系),熔点为630.74℃,沸点为1750℃,相对密度为(d^{25}) 6.684。它溶于热浓硫酸和王水,而不溶于水。

用途
主要用于制造Ⅲ~V族化合物半导体、高纯合金及硫化锑,并用作制冷元件、硅和锗单晶的掺杂剂等。此外,也可作为分析试剂和合金与盐的制备材料;用作高纯试剂和半导体原材料;用于制造铅锑合金材料、电缆护套以及生产锑化合物。

生产方法
工业生产包括蒸馏法和区域熔融法。通过蒸馏法制备金属锑时,将锑块加入反应器中,并通入氯气进行氯化反应,生成三氯化锑。随后将粗品三氯化锑加入蒸馏器中,在减压条件下除去五氯化锑及其杂质;在常压下继续蒸馏,取221~225℃的馏分冷却结晶后得到三氯化锑。再经还原处理后可制得纯度≥99.999%的金属锑,并以此为原料进行双精馏提纯,最终制得高纯锑(纯度≥99.9999%)。
