摘　　要：用原子吸收光谱仪测定北太湖沉积物重金属元素Fe、Mn、Zn和Cu的含量,结果表明:北太湖沉积物中重金属元素含量不同类型差异大小依次为Fe>Mn>Zn>Cu、不同区域含量大小依次为梅梁湾>大浦口>贡湖湾(除Fe外);不同元素季节性变化幅度依次为Mn>Fe>Zn>Cu、其中贡湖湾重金属元素呈现出Mn和Fe元素含量为冬>夏、Zn和Cu含量为冬春>夏秋的季节性特征。The concentration of Fe, Mn, Zn and Cu in the sediments of northern Lake Taihu were determined using PE 5100PC AAS. The results show that the heavy metal elements are in the sequence of Fe 〉 Mn 〉 Zn 〉 Cu in term of concentration, of Meiliang Bay 〉 Dapukou 〉 Gonghu Bay in term of regional concentration （inclusive of iron element）, and of Mn 〉 Fe 〉 Zn 〉 Cu in term of seasonal concentration variation. With respect to the heavy metals in Gonghu Bay, the Mn and Fe concentrations in winter are greater than in summer and the Zn and Cu concentrations in winter and spring are greater than in summer and autumn.
