本文从锌的生产过程、用途及来源三方面论述有关锌暴露的问题。自然界中很少存在元素锌,锌产品大多由硫化锌矿加工而成。金属锌的生产主要是通过电解加工或通过氧化锌、加热、煤和硫酸的熔炼而产生。在熔炼、焊接、电镀、铜铸造操作中发生锌的职业性暴露。在介绍金属锌及其化合物的用途时,叙述了相关的锌暴露情况。锌暴露的来源还包括空气、土壤、水、食物、血液透析液等。
This article discusses the issues related to zinc exposure from the three aspects of zinc production process, use and source. Few elements in nature zinc, zinc products are mostly processed from zinc sulfide mine. Metallic zinc is produced primarily by electrolytic processing or by zinc oxide, heating, smelting of coal and sulfuric acid. Occupational exposure to zinc occurs during smelting, welding, electroplating, and copper casting operations. In describing the uses of zinc metal and its compounds, the associated zinc exposure is described. Sources of zinc exposure include air, soil, water, food, hemodialysis, and more.
