代谢
铅通过吸入、口服和皮肤接触被吸收,然后主要分布到骨骼和红细胞中。在血液中,铅可能被发现与血清白蛋白或金属结合蛋白金属lothionein结合。有机铅通过细胞色素P-450酶代谢,而无机铅则与δ-氨基酮酸脱水酶形成复合物。铅主要通过尿液和粪便排出。
Lead is absorbed following inhalation, oral, and dermal exposure. It is then distributed mainly to the bones and red blood cells. In the blood lead may be found bound to serum albumin or the metal-binding protein metallothionein. Organic lead is metabolized by cytochrome P-450 enzymes, whereas inorganic lead forms complexes with delta-aminolevulinic acid dehydratase. Lead is excreted mainly in the urine and faeces. (L136)

  • 毒性总结
铅模仿其他生物学上重要的金属,如锌、钙和铁,作为许多它们各自酶促反应的辅因子与之竞争。例如,铅已被证明能竞争性地抑制钙与钙调蛋白的结合,干扰神经递质的释放。它对NMDA受体和蛋白激酶C表现出类似的竞争性抑制,这损害了脑微血管的形成和功能,并改变了血脑屏障。铅还通过阻碍多巴胺合成的调节和阻止乙酰胆碱的诱发释放来影响神经系统。然而,其主要作用机制是通过抑制δ-氨基酮酸脱水酶,这是一种在血红素生物合成中至关重要的酶,而血红素是血红蛋白所需的必要辅因子。(T4, A20, A22, L136)
Lead mimics other biologically important metals, such as zinc, calcium, and iron, competing as cofactors for many of their respective enzymatic reactions. For example, lead has been shown to competitively inhibit calcium's binding of calmodulin, interferring with neurotransmitter release. It exhibits similar competitive inhibition at the NMDA receptor and protein kinase C, which impairs brain microvascular formation and function, as well as alters the blood-brain barrier. Lead also affects the nervous system by impairing regulation of dopamine synthesis and blocking evoked release of acetylcholine. However, it's main mechanism of action occurs by inhibiting delta-aminolevulinic acid dehydratase, an enzyme vital in the biosynthesis of heme, which is a necesssary cofactor of hemoglobin.

  • 健康影响
铅是一种神经毒素,已知会导致大脑损伤和认知能力下降,特别是在儿童中。铅暴露可能导致肾病,以及如高血压和贫血等血液疾病。铅还表现出生殖毒性,可能导致流产和减少精子产生。
Lead is a neurotoxin and has been known to cause brain damage and reduced cognitive capacity, especially in children. Lead exposure can result in nephropathy, as well as blood disorders such as high blood pressure and anemia. Lead also exhibits reproductive toxicity and can results in miscarriages and reduced sperm production. (L21)

吸收、分配和排泄
通过皮肤剥离法测量了10名铅酸电池工人的皮肤表面的铅含量,并通过四种铅化合物的经皮给药测量了大鼠尿铅含量:硫酸铅、氧化铅、铅粉和铅硬脂酸。在铅工人的手背和背部第9和第10次皮肤剥离中发现了大量的铅。手背上的铅含量与血液中的铅含量显著相关(n = 10, r² = 0.66, p < 0.05,线性回归)。在大鼠中,铅化合物给药12天后,尿液中的总铅量显著增加,铅硬脂酸为146.0 +/- 6.4 ng(标准差),硫酸铅为123.1 +/- 7.2 ng,氧化铅为115.9 +/- 5.3 ng,铅粉为47.8 +/- 6.9 ng,对照组为10.3 ng,这表明有显著的皮肤吸收。结论是,大量的无机铅化合物可以通过皮肤吸收,在铅作业或任何污染环境中,应当仔细考虑皮肤保护。
... The lead content on the skin surface of 10 lead-battery workers was measured by the method of skin stripping, and urinary lead content of rats was measured with epicutaneous application of four lead compounds: lead sulfate, lead oxide, lead powder, and lead stearate. There were significant amounts of lead on the 9th and 10th skin strippings of the dorsal hand and the back of lead workers. The amount of lead on the dorsal hand was significantly correlated with the amount in the blood (n = 10, r 2 = 0.66, p < 0.05, linear regression). In rats, after lead compounds were applied for 12 days, total lead amount in urine significantly increased to 146.0 +/- 6.4 ng (SD) for lead stearate, 123.1 +/- 7.2 ng for lead sulfate, 115.9 +/- 5.3 ng for lead oxide, 47.8 +/- 6.9 ng for lead powder, and 10.3 ng for the control, which indicated significant skin absorption. It was concluded that significant amounts of inorganic lead compounds can be absorbed through the skin, and skin protection in lead-working or any contaminated environment should be carefully considered.

    DOI:10.1149/1.1393318
    日期:——
    The electrochemical deposition of metals from Me II (ethylenediaminetetraacetic acid, EDTA) complexes was studied by electrochemical quartz crystal microgravimetry. These investigations are important for the development of environmental clean-up processes, such as remediation of metal-contaminated soils by EDTA and subsequent electrochemical recovery of metal, in situ electrokinetic soil remediation
    Me II(乙二胺四乙酸,EDTA)配合物的金属电化学沉积通过电化学石英晶体微重量法进行了研究。这些研究对于环境清理过程的发展具有重要意义,例如 EDTA 修复金属污染土壤和随后的金属电化学回收、原位电动土壤修复、电化学气体净化等。对 Pb、Cu、Cd、Zn 和 Ni 等废物位点进行了调查。从电极质量的明显增加中检测到金属沉积的潜在区域。我们观察到质子化和非质子化 EDTA 络合物中 Pb、Cu、Cd 和 Zn 的还原。没有发现镍沉积的迹象。而 Cu、Cd 的扩散限制电流,并且可以实现 Pb 沉积,Zn 沉积电流要低得多。这可以用锌沉积过程中的电极钝化来解释。确定了副反应,即质子还原、EDTA 还原和水分解。

    Beveridge and Denbigh1 have directed attention to the development of a concentric shell of zinc oxide when a compressed sphere of zinc sulphide powder was oxidized in air at 1,250° C. This shell was presumed to arise from the reaction between zinc and sulphur diffusing outwards from the surface of the zinc sulphide and oxygen diffusing inwards. The distance between the core and the shell increased
    Beveridge 和 Denbigh1 已将注意力集中在硫化锌粉末的压缩球体在 1,250°C 下在空气中氧化时,氧化锌同心壳的发展。据推测,该壳是由锌和硫之间的反应产生的,从硫化锌的表面和向内扩散的氧。核与壳之间的距离随着温度的升高而增加,并且壳的直径大于原始核的直径。在方铅矿(硫化铅)晶体氧化为硫酸铅的过程中,我们观察到形成了近似球形的产物层,与方铅矿晶体分离并与方铅矿晶体同心。该产品层的形成机制似乎与氧化锌所提出的机制不同。

    Abstract The product formed from the reaction between aqueous lead acetate solution and sodium dodecylsulphate is identified as basic lead(II) dodecylsulphate. This decomposes thermally in a single stage process over the temperature range 450–625 K to yield lead sulphate and 1-dodecanol as major products. The kinetics have been studied thermogravimetrically using the modified method of Freeman and
