摘　　要：以海口市大气总悬浮物颗粒物(TSP)和可吸入颗粒物(PM10)为主要研究对象,利用等离子电感耦合发射光谱仪(ICP-AES),分别对海口市不同粒径大气颗粒物中Pb、Zn、Cu、Cd、Ni、Cr、V、Co、Mn、Ca 10种重金属元素进行了首次分析。监测分析结果表明,海口市春季大气颗粒物中不同重金属元素浓度相差很大,主要元素为Fe、Zn和Pb;海口市大气颗粒物中不同重金属元素主要分布在PM10中;与全国其他城市相比,海口市春季大气颗粒物中重金属含量相对较低;Pb、Cu、Zn、Cd四个元素富集系数大于10,人为源贡献大于自然源,是环境治理的重点。With TSP and PM10 of Haikou as the main study object,10 major and trace metals in different sizes of atmospheric particles were analyzed by ICP-AES.The results showed that the concentration of different heavy metals varied greatly in atmospheric particles in Haikou,the major elements were Fe,Zn and Pb;the heavy metals of atmospheric particles were mainly distributed in PM10;compared with other cities,the heavy metals in atmospheric particles in spring of Haikou were relatively low.Four elements including Pb,Cu,Zn and Cd with enrichment factors over 10 were affected by human activities and would be the focus of pollution control.
