Benzo[a]pyrene
✡ Introduction
(1)Why do we detect benzo[a]pyrene?
Because when food,such as fried food ,which is heated above 300 degrees
celcius,food will release benzo[a]pyrene recycled oil usually contain
benzo[a]pyrene[1].
(2)Harm?
Pathway:from skin,breathing in,eating Carcinogenic,environmental
pollution, Skin irritation,eye irritation[1].
(3)Taiwanese regulation
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)
