 Mercury

 ✡ Introduction

   (1)為何偵測此毒物?

   通常食用油中是不會含有如此超標的重金屬汞。食用油裡會含有超標的汞

   原因是動物攝入甲基汞後囤積於內臟（註1），而餿水油是由內臟油加工

   製成，但汞不容易被人體代謝掉進而累積在體內造成嚴重的疾病，所以我

   們才會偵測汞這個重金屬。

   (2)此毒物的危害

   甲基汞是已知的神經毒物，會抑制神經細胞的分裂及電離子的移動並干擾

   發育中的腦部結構，除此之外，甲基汞還能引起心血管疾病包括心肌梗塞

   與缺血性心臟病、高血壓及心律不整（註2）。

   (3)相關法規

   食用油脂類衛生標準第二條：重金屬及芥酸之最大容許量：汞0.05 ppm

   食米重金屬限量標準第二條：食米中重金屬含量應符合以下限量：0.05ppm。

 ✡ Circuit Design

   MerR可以和汞結合然後改變DNA的結構好讓RNA聚合酶方便轉入。

   PmerT可以被MerR控制。PmerT步行進行轉錄是因為MerR會改變PmerT的

   形狀。總而言之，只要汞與MerR結合，後續反應就可進行。(註3)(註4)
