为全面了解海洋生物体内稀土元素的分配模式,采用ICP-MS测定山东东部近海海域主要海洋生物体内稀土元素含量,浓度范围为30.17μg·kg~(-1)~807.33μg·kg~(-1),其中蓝点马鲛(Scomberomorus niphonius)<牙鲆(Paralichthys olivaceus)<刀额新对虾(Metapenaeus ensis)<疣荔枝螺(Thais clavigera)<刺参(Apostichopus japonicus)<贻贝(Mytilidae)<海带(Laminaria japonica);7种海产品均明显富集轻稀土,轻重稀土的比值在3.6~51.7之间,底栖鱼类对轻稀土的富集性最大;7种海洋生物稀土含量经北美页岩标准化后,基本都呈近似平坦而略有轻稀土富集的分布趋势,即海洋生物对稀土元素的利用遵从丰度规律;南北方海域水体中稀土浓度相差不大,平均值为0.75μg·kg~(-1)~15.06μg·kg~(-1),水体pH为7.54~8.14,同一海域,藻体中稀土元素含量与pH呈负相关。 In order to comprehensively understand the pattern of REE distribution in marine organisms, the content of rare earth elements in the marine organisms in the offshore area of ​​eastern Shandong was determined by ICP-MS with the concentration range of 30.17μg · kg -1 ~ 807.33μg · kg -1 ), Of which Scomberomorus niphonius
