Benzo[a]pyrene

(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

[2]

(4)National regulation

Europe:The same to Taiwanese regulation[2]

American:The MCL has been set at 0.2 ppb[3]

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)
