    摘要: 本文根據八里焚化廠和林口發電廠附近觀測站測量的戴奧辛濃度值，就三種不同環境介質來檢定何者為污染源。我們使用排列檢定及百分比同質性檢定這兩種方法來討論。我們可以建立統計模式來討論三種介質的濃度，接著再透過貝氏方法經由WinBUGS求得參數的事後分布進而得到未知點濃度。但是我們的資訊有限，若能加入更多影響因素，相信結果會更精確。
    In the present study, analyses were based on the concentration values of dioxin which were measured near the observations of Bali-incinerator and Linkou-power plant. Three different environmental media were used to detect that which one is the pollution source. We used the permutation test and the test of homogeneity of proportions to discuss it. We can establish the statistical model to discuss the concentrations of three media. Therefore, then using WinBUGS software by the posterior distributions of the Bayesian spatial model to obtain the unknown concentration in unknown observations. However, our information is limited. If we can add more determined factors, we believe that the results could be more accurate.
