摘　　要：于 2 0 0 1年 4月— 2 0 0 2年 5月在青岛近海三个采样点采集了 1 0 0多个大气气溶胶样品 ,用ICP AES测定了Al,Fe ,Mn ,Cu ,Pb和Zn的浓度 ,讨论了这几种元素的时空分布特征及其来源 .结果表明 ,六种元素浓度的时空分布特征为 :沧口 >八关山 >仰口 ,TSP(总体悬浮颗粒物 )与Al,Fe ,Mn的浓度呈明显的季节变化 :春季 >冬季 >秋季 >夏季 ,而Cu ,Pb ,Zn的季节变化比较复杂 .六种元素中Al,Fe,Mn主要由自然过程输入 ,而Cu ,Pb ,Zn主要是人为来源 .The dry atmospheric deposition of aluminium,iron,manganese,copper,lead and zinc was sampled at biweekly intervals for one year,from April 2001 to May 2002 at three sites in Qingdao coastal area,Yangkou,Baguanshan and Cangkou.Their respective concentrations were measured,and the spatiotemporal distributions and sources of these trace metals were discussed.The results indicated that the spatial variability trend is Cangkou>Baguanshan>Yangkou.TSP and Al,Fe,Mn concentrations showed obvious seasonal variability,whereas Cu,Pb and Zn took on the complicated variability.Using Al as the crustal reference,the enrichment factors indicated that Cu,Pb and Zn were mainly associated with anthropogenic aerosols,and Al,Fe,Mn were mainly associated with crustal aerosols.
