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 trans...
