| 摘 要： | 在大量实验数据的基础上，研究了中国四城市空气颗粒物中铅的污染水平。探讨了颗粒物中铅的数据分布属对数正态分布类型。分析了铅在ＰＭ２５及ＰＭ１０中的分配比例，指出铅在对人体危害较大的细颗粒物中含量占绝大部分。同时分析了铅在粗细颗粒物中铅的富集因子，结论指出铅更易富集在细颗粒物中

| Abstract: | Based on large amount of data,this paper studies on the lead pollution level in particulate in the 4 cities of China.Data distribution test shows that it belongs to logarithmic normal model.The percentage of lead in PM25 over PM10 is also researched.It shows that major lead contains in PM25.Meantime,it studies the enrichment factor of lead,the results also prove that lead tends to enrich in fine particulate. |
