中文摘要：

以蓝斑背肛海兔（Notarchus Leachii cirrosus Stimpson，NLCS）为实验材料，研究NLCS经人工海水净化前后，NLCS各器官组织中有机态（结合态）／无机态（游离态）重金属含量相对比值及变化趋势，提出组织细胞中的有机态／无机态重金属比值参数，适合于监测流动海水中各类重金属污染程度及危害性的看法．实验结果发现，NLCS受铜盐污染后，海兔器官组织内的有机态／无机态重金属的比值应低于0．85；受Cd、Pb和Ag盐分别污染后，NLCS各器官组织中的有机态／无机态的Cd、Pb和Ag相对含量比值，分别为1．43～1．55、1．47～2．05和1．78～1．89；金属Mn的安全比值很高，但它的阈值却低于10．21．NLCS各器官组织中有机态／无机态重金属相对比值可作为连续监测流动海水中重金属污染程度及危害性的新颖标志参数，它比选用直接分析动植物及微生物机体中总金属含量作为评价环境污染程度的经典分析法，更为科学且合理，并具有潜在的应用前景．

英文摘要：

The experimental materials of Notarchus Leachii cirrosus Stimpson （NLCS） were treated with depurated seawater. Then the relative ratio and variation trend of organic （combined form） to inorganic （disassociated form） heavy metal content in various organic tissues of NLCS were revealed and compared, respectively. Results indicate that these ratio parameters are fit for monitoring and evaluating various heavy metals for bringing both pollution level and crisis in flowing seawater. The experimental results indicated that the ratio of organic to inorganie heavy metals in the various organic tissues of NLCS was lower than 0. 85 in the contami- nation seawater of copper chloride. Moreover,another relative ratios such as 1.43 - 1.55 （Cd）, 1.47 - 2.05 （Pb）, and 1.78- 1.89 （Ag） of organic to inorganic heavy metals were found in the various organic tissues of NLCS while contaminated with Cd,Pb,and Ag salts,respectively. Though the safe ratio of metal Mn showed relative high,its liminal value was lower than 10. 21. The relative ratio values of organic to inorganie heavy melts in various organic tissues of NLCS were novel biomarkers. They can be used to monitor the contamination level of heavy metals and crisis in the flowing seawater continuously. It is obvious that this approach is more aceurate and science than that of typical analytical methods such as total metal content in cell, animal, plant, microorganism as previously described. So this approach has the potential in application.
