摘要
使用自动采样器连续72h采集海口市4个城市功能区样点的空气颗粒物(TSP和PM_(10))和样点附近的城市表土,并测定其中的Pb、Cd、As、Cu、Zn、Fe元素含量,发现海口市冬季空气TSP和PM_(10)中的Pb、Cd和As浓度远低于其在GB 3095—2002《环境空气质量标准》中的限值,重金属主要分布在颗粒物PM_(10)上;商业区TSP和PM_(10)中的Cd、Cu、Zn和As含量显著高于其他区域(P<0.05)。5种重金属在TSP和PM_(10)中的富集因子相对较高,属中重度污染水平。
In this paper,total suspended particulate（TSP） and PM_（10） samples in ambient air from 4 urban functional areas of Haikou city were collected for 72 consecutive hours,and topsoil nearby samples were collected.Then contents of Pb、Cd、As、Cu、Zn、Fe in TSP,PM_（10） and soil samples were analyzed.The results suggested that concentrations of Pb、Cd and As were far lower than the limit values for those metals provided according to ＂National Ambient Air Quality Standard ＂（GB 3095—2002）; the 6 heavy metals mainly assembled on PM_（10）.The level of Cd、Cu、Zn and As in TSP and PM_（10） in downtown area were higher than other areas significantly（P 0.05）.The air quality in Haikou City were polluted severely by heavy metals according to the higher enrichment factors of Pb、Cd、Cu、Zn and As.
