Why do we detect mercury?
Normally, there is no excess heavy metal in edible oil. Ingested mercury will hoard in the organs. Some recycled oil is made from animal internal organs. After mercury enters our body, it cannot be metabolized effectively and this leads to serious diseases. Due to the reasons above, we decided to detect this heavy metal.[1]

Methyl mercury is a type of neurotoxin. It represses cell division and restricts motility of electronic ions. It can also interfere with growing brain structure. Besides, methyl mercury can result in cardiovascular diseases like myocardial infarction, ischemic heart disease, hypertension and irregular pulse.[2]
