| 摘 要： | 水是环境中污染物迁移的重要介质,水系污染物也可以直接作用于生物体。本文概述了对水系物质迁移过程示踪的各种方法,包括人工示踪剂方法、生物标志法、微量元素及同位素示踪方法等,指出了它们的环境应用价值。在人工示踪法中叙述了中子活化示踪沙技术和稀土元素-DTPA螯合物示踪法。生物标志物主要叙述了木质素、正构烷烃、脂肪酸的指示意义。微量元素示踪主要涉及到Sr、Ca、Mg和REE的示踪。同位素示踪法着重阐述了较先进的碳、氮、氧和铅同位素的示踪。最后展示了水系物质示踪的应用前景。

| Abstract: | The water is the important media of pollutant transferring in the environment, and the material in the water can take effect on the biologists directly. This paper has discussed the methods of tracing the characteristics of pollutants existing in the different water environment, including the method of using artificial tracer, the biomarker signal method, the microelement tracer method and the isotopes tracer method, and connect them with the environmental research. In the paragraph of the method of using artificial tracer, there is the explanation about the tracer technology of neutron activation analysis and the method of Lanthanide-DTPA tracer. The biomarker signal method mainly explain the lignin, the n-alkane and the fatty acid. The microelement tracer method is mainly about Sr, Ca, Mg and REE (rare earth element) tracing. The isotope tracer method presents the advanced method of carbon isotope, nitrogen isotope, oxygen isotope and Pb tracer. The content in the end of this paper is the expectation of the application in the environment for tracer methods. |
