摘要
从地理学科角度，联系发达国家铅污染的演变 轨迹，及 我国铅污染源的结构性特征及其演变趋势，对受到铅污染严重威胁的人群的群体特征按年龄 结构、职业结构、城乡差别及群体规模与发展趋势作了具体分析。结果显示，我国约有４２ ．２％的城乡儿童血铅高于目前国际公认的１００μg/L儿童铅中毒诊断标准；涉铅中小型 乡镇企业职工铅中毒患病率９．３５％。其中蓄电池、冶炼行业最高，铅中毒患病率分别为 ２３．８％和１８．８％，占总中毒人数的６７．２％。
From the angle of geography,referred to the evolut ion track of lead pollution from the developed countries,and the structural characteristics and e volu tion trend of lead pollution sources in China,the article analyzed mainly ag e structure,occupation structure,the differences of town and country as well as colony scale and developing trend of people to be subjected lead pollution．The results show that about ４２．２％ children of town and country are found with a blood lead level≥１００μg/L（the diagnostic criterion of lead poisoning of ch ildren）．There is ９．３１％ prevalence rate of lead poisoning in the occupatio nal workers at the small and medium－sized village and township enterprises,whic h at storage battery plants and smelters is ２３．８％ and １８．８％ respec tively,accounting for ６７．２％ of the total sum together．
