In the process of cooling down boiling water, the temperature is just very suitable for the reproduction of microorganisms and bacteria. The longer it takes, the more it will reproduce, just like a pot of water left outside, which will deteriorate for a long time.

How long will it go bad and be unfit for drinking? In fact, there is no fixed time, because it is also affected by the objective environment.

Generally, the one-time safe intake of nitrite for human body is 0.2 mg/kg body weight. In the sanitary standard for drinking water, it is stipulated that the nitrite content should not exceed 10 mg/L. If you drink water at one time, it is safe.

With the increase of boiling times, the nitrite content in water has no obvious upward trend. However, the nitrite content of all water samples is lower than the limit value of nitrite content 10 mg/l stipulated in the Hygienic Standard for Drinking Water (GB5749-2006). The specific data can be seen in this edition of the picture. The nitrite content of boiling water is even lower than that of mineral water.
