测定了在黄海采集的各种体长的鳀鱼(Engraulis japonicus)中6种痕量金属(Zn、Cu、Fe、Al、Mn和Sr)和3种主要元素(C、N和P)的浓度.除Zn浓度在4～5倍内变动外,其余5种痕量金属浓度的变动范围均接近或超过一个数量级;并且,这6种金属均显示出了浓度随体长增长而下降的趋势.对于3种主要元素,N和P的含量也与体长存在负相关关系,而C却显示出了强烈的正相关关系.聚类分析表明,Zn和Cu在鳀鱼内的浓度变化较为接近,可能验证了这两种金属与生物体内新陈代谢活动较为密切的性质;而其余4种金属的浓度变化规律更为接近,可能反映了陆源输入的影响.

The Concentrations of six trace metals (Zn,Cu,Fe,Al,Mn,and Sr) and the three major elements (C,N,and P) in Japanese anchovy (Engraulis japonicus) collected from Yellow Sea were measured.Except for Zn,whose concentrations varied in a 4～5-fold ranges;the concentrations of other five metals varied by approximately an order of magnitude.The concentrations of six metals showed the negative relationships with body length.Among three major elements,N and P showed the negative relationships similar to six trace metals,whereas C displayed a strong positive linear correlation.The cluster analysis suggested that variations of Zn and Cu concentrations were more similar with each other,presumably reflecting their same properties as essential elements in fish metabolism.However,other four metals were grouped into the other category in which their concentrations seem to be more associated with the terrestrial origin.
