砷广泛存在于自然界中,如石头,土壤,空气和生物中。其在农业、工业、医学领域都具有重要的作用。研究表示世界上数以百万计的个体惨遭砷中毒的危害。本文作者从砷的性质入手,介绍了砷的物理、化学性质,并总结了砷在自然界中的分布,主要为在水、空气、土壤、生物中的分布以及其在各部分中的含量;同时介绍了砷在工业(主要为矿业)、农业以及药品中的应用。介绍了砷问题在世界上的分布并列举了对一些国家以及其在流行病学和农业中的影响,同时总结了一些前人的补救方法,如使用地质材料作为天然吸附剂等。调查发现,植物修复比传统修复方式更有优势,如一些热带和亚热带植物物种和豆科植物。
Arsenic is widespread in nature, such as rocks, soils, air and organisms. It plays an important role in agriculture, industry and medicine. Research shows that millions of individuals in the world are harmed by the arsenic poisoning. The author starts with the properties of arsenic, introduces the physical and chemical properties of arsenic, and summarizes the distribution of arsenic in nature, mainly in water, air, soil, biological distribution and its content in various parts; meanwhile, The application of arsenic in industry (mainly mining), agriculture and pharmaceuticals was introduced. The distribution of arsenic in the world was introduced and its impact on epidemiology and agriculture in some countries was outlined. Some previous remedies, such as the use of geological materials as natural adsorbents, were summarized. The survey found that phytoremediation has more advantages than traditional restoration methods, such as tropical and subtropical plant species and legumes.
