| 摘 要： | 运用环境多介质QWASI等量浓度模型模拟了三峡水库水环境中内分泌干扰物TBT在各环境介质中的浓度分布及迁移归趋,同时讨论了三峡水库运行方式对库区水环境中TBT环境行为的影响.结果表明,QWASI模型能够较为合理地给出各个物理化学过程的速率参数,可对TBT在三峡水库这种超大型河道型水库中跨介质间的迁移传输、各环境相分布等作出定性和定量的模拟估计,模型输出结果与实测结果较为吻合.研究表明,三峡水库的运行方式对TBT在库区水环境中沉积物和水相间的迁移转化有重要影响.

| Abstract: | In the study, the distribution, transfer and fate of the endocrine disruptors TBT in various environmental media of the Three Gorges Reservoir (TGR) water environment were simulated by a multimedia environmental QWASI equivalent model. The impacts of operation mode of TGR on TBT environment behavior were also discussed. The results showed that QWASI model not only gave reasonable rate parameters of various physical and chemical processes, but also made qualitative and quantitative simulation estimates of transfer and distribution for TBT among multimedia in the TGR, a large river-type reservoir. The output of model was basically consistent with the monitoring results. Moreover, the operation mode of the TGR showed an important influence on the environmental behavior of TBT in sediment and water of TGR. |
