铝产品广泛应用于工农业、医药生产及人类日常生活等各方面,接触人数极多。经过多年来研究证明,铅对人体各系统、器官均有毒性作用,主要影响人体的神经系统、消化系统、血液系统、泌尿生殖系统等[1-2],铅被人体器官摄取后,将抑制蛋白质的正常合成功能,危害人体中枢神经,造成精神混乱、呆滞、生殖功能障碍、贫血,高血压等慢性疾病[3]。ACGIH(1995)已将铅列为动物致癌物[4]。本项目旨在对一所新建铝厂排放的铅对环境污染开始,以后随着生产过程逐年增加,研究其对环境的影响。本实验通过对一所新建铝厂周围土壤样品进行铅元素测定分析。
Aluminum products are widely used in industry and agriculture, pharmaceutical production and human daily life and other aspects, the extremely large number of contacts. After years of research, lead has a toxic effect on various systems and organs of the human body, mainly affecting the nervous system, digestive system, hematological system and genitourinary system of the human body [1-2]. When lead is taken up by human organs, it will inhibit The normal synthesis of protein function, endanger the body’s central nervous system, resulting in mental disorders, sluggish, reproductive dysfunction, anemia, hypertension and other chronic diseases [3]. ACGIH (1995) has listed lead as an animal carcinogen [4]. The project aims to start lead emission from a newly built aluminum plant to environmental pollution and to study its impact on the environment as the production process increases year by year. In this experiment, the lead content of soil samples around a new aluminum plant was analyzed.
