目的:通过对砷在自然界中的分布情况,以及它的结构和特性,探讨其对人类的作用与危害。结果:砷是地壳的构成元素之一,也是生物体的必需微量元素之一,低剂量的砷有一定的生血刺激作用,能促进细胞生长和繁殖,但过量摄入则会导致中毒甚至死亡。结论:砷及其化合物在工农业、医药等生产上有广泛的应用,但在冶炼过程中会产生含砷的废气、废水、废渣等有害物质,危害环境和人类的健康。
OBJECTIVE: To explore the effect and harm of arsenic on human beings through the distribution of arsenic in nature and its structure and characteristics. Results: Arsenic is one of the constituent elements of the crust. It is also one of the essential trace elements of organisms. Low dose of arsenic has a hematopoietic stimulating effect and can promote cell growth and reproduction. However, excessive intake of arsenic causes poisoning and even death. Conclusion: Arsenic and its compounds have a wide range of applications in industry, agriculture and medicine. However, harmful substances such as waste gas, waste water and waste residue generated during the smelting process are produced, which endanger the environment and human health.
