摘　　要：１９７９～１９８５年用大口径静压取样器采集了渤海２８柱未扰动岩心样。采用￣（２１０）Ｐｂ年代学方法，通过柱样沉积物稳定天然密度资料获得沉积速率、沉积通量和岩心编年，以此提出了渤海细颗粒（＜０．０６３ｍｍ）沉积物中Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ环境背景值，探讨了渤海重点海域和毗邻河口区重金属污染历史。undisturbed core samples of Bohai Sea was collected with big-bore static pressure sampler from 1979 to 1985.By￣(210)Pb age dating method,the sedimentation rate,sedimentation flux and core annals was obtained through the data of stable natural density of sediment,and then the environment background values of Cu,Pb,Zn,Cd of fine particles(<0.063mm)in sediment was put forward. Finally,the pollution history of heavy metals in main sea area and adjacent river mouth was studied.
