摘　　要：根据渤海湾及其毗邻河口区10柱岩芯样细颗粒(<0.063mm)(于1983—1985年采集)中重金属含量特点,结合^(210)Pb年代学编年资料,用未受人类影响沉积层中元素含量,藉统计学方法获得渤海湾岩芯样中Cu,Pb,Zn,Cd的分布类型,并根据各区重金属的含量水平,用t检验法获得了渤海湾Cu,Pb,Zn,Cd的环境背景值。10 core samples were collected with the long-box and static pressure sampler in the Bohai Bay and adjacent estuary areas during 1983-1985. Based on the heavy metal concentrations in the fine grain (less than 0.063mm) and the chronicle data of 210Pb chronology of the cores from the Bohai Bay and adjacent estuaries the distribution types of Cu, Pb, Zn, Cd, uninfluenced by mankind are obtained by means of the statistical method; and then, the environment background concentrations of Cu, Pb, Zn,Cd of whole Bohai Bay determined by t-test according to the different content of heavy metals are 25.63×10-6, 16.55×10-6, 74.61×10-and 0.112×10-6, separately.
