Recently, there has been a widespread rumor in the circle of friends in WeChat saying that steamer water contains a large amount of nitrite, and people who drink it accidentally can cause cancer. Is the truth really like this?
Steamer water refers to steamed bread. According to China's "Sanitary Standards for Drinking Water" (GB5749-2006), the content of nitrate in drinking water should be ≤ 10 hl/l (groundwater source is limited to ≤ 20 mg/l), and the nitrite content should be ≤ 1 In milligrams per liter, trace amounts of nitrates and nitrites are allowed in drinking water.
If the water is boiled or boiled for a long time, the nitrate is decomposed into nitrite or lead and other heavy metals remain in the steamer water. Nitrite poses two hazards to the human body. First, nitrite can oxidize the normal iron-carrying methemoglobin in human blood to methemoglobin, which can not combine with oxygen to cause oxygen deficiency in the body. Second, nitrite can cause blood pressure to decrease due to vasodilation, resulting in severe blood pressure. collapse.
It is noteworthy that nitrite itself is not carcinogenic, and it is only carcinogenic when converted to nitrite amines. Therefore, the nitrites mentioned in WeChat are a kind of strong carcinogenic substance.
