ProjectMercury

Introduction

  1. Why do we detect mercury?

    Normally, there wont be such amount of heavy metal be contained in edible oil. Edible oil excessive mercury is because methyl mercury will be hoard in animal internal organs after eating by them. And recycled oil was made from animal internal organs . After we eat recycled oil into our body, it wont be metabolized easily and lead to serious disease. Due to the reasons above, we decided to detect this heavy metal.[1]

  2. The harm of mercury

    It's common knowledge that Methyl mercury is neurotoxin . It represses cell division and restricts motility of electronic ions. It can also interfere with growing brain structure. Besides, methyl mercury can also result in cardiovascular disease like myocardial infarction, Ischemic Heart Disease，hypertension and irregular pulse.[2]

  3. Taiwanese regulations
    • Edible Fat and Oil Sanitary Standards Article 2: The maximum allowance for Heavy Metal and Erucic acid: Mercury 0.05 ppm
    • Edible Rice and Heavy Metal Restriction Standard Article 2: permissible percentage limits for edible rice and heavy metal: less than 0.05ppm

Circuit Design

MerB can turn Methyl mercury into Hg2+.MerR can combine with Hg2+ and change the structure of DNA. And DNA can be trancripted easier. PmerT is controlled by MerR. PmerT cannot be transcripted because MerR changes the shape of PmerT. In short, the whole reaction will continue if MerR combines with Hg2+.[3][4]
