摘要
为了解湖北省某钢铁厂周边铅污染的现状，通过对钢铁厂工业区及其周边乡村的土壤、蔬菜、居民体内和排污渠污泥中铅元素含量的研究，其结果表明：钢铁厂周围的土壤、蔬菜、居民均受到了一定程度的铅等重金属元素的污染，其含量高于国家标准或正常范围；钢铁厂工业区周边土壤铅污染主要由于工业废气（烟尘）扩散沉降和废水灌溉引起；污染区人体尿样中铅元素含量（116～160ng／mL）普遍超标，头发样（2．09-12．04μg／g）基本正常，尿样比头发样更能显示铅等重金属元素在人体内的分布特征。
In order to understand the present situation of Pb pollution around an steel industrial area in Hubei Province, an investigation of the content of Pb element in the soil, vegetables and the inhabitants of the peripheral villages around the steel industrial distriet was earried out. The researeh indieated that the Pb element content of the peripheral villages around the steel industrial district is higher than that of the state standard or the normal range, and the inhabitants have been polluted to certain degree. Furthermore, the Pb eontamination of soil is mainly eaused by industry waste gas （mist and dust） diffusion and the irrigation of farmland by waste water. Moreover, the Pb element in human urine is overloaded at the eontaminated area though the hair is within normal range. So the urine sample can demonstrate the distribution eharaeters of Pb element in the human body in a better way than the hair sample.
