New Year's Day is healthy
Be merciful!The real carcinogenic water is not the overnight water, but it
1. In recent years, rumors about the carcinogenesis of drinking water have emerged one after another.
Poor, among which thousands of boiling water and overnight water are accused of being the culprits of carcinogenesis. However, these rumors often lack scientific basis and can easily mislead the public and cause unnecessary panic. In fact, the real carcinogenic water is not boiling water or overnight water, but water containing specific harmful substances. This article will delve into these harmful substances and how to avoid ingesting these carcinogenic waters.
Second, the truth of thousands of boiling water and overnight water.
Boiling water refers to water that has been boiled repeatedly, while overnight water refers to water that has been left overnight. The claim that these two types of water are carcinogenic is mainly based on the increase in the nitrite content of the water. In practice, however, nitrite levels are very low in normal drinking water, and the nitrite levels in boiling water and overnight water do not exceed safety standards. In addition, the relationship between nitrite and cancer has not been fully proven.
Therefore, we can assume that boiling water and overnight water are not carcinogenic.
3. Water that is truly carcinogenic.
Compared with boiling water and overnight water, water containing specific harmful substances is truly carcinogenic. These hazardous substances mainly include:
1.Heavy metals: such as lead, mercury, cadmium, etc., these heavy metals are soluble in water, and long-term drinking of water containing heavy metals may lead to poisoning and even cause cancer.
2.Organic pollutants: such as pesticides, phenols, etc., these pollutants accumulate in water for a long time, which can lead to genetic mutations and cancer.
3.Carcinogens: such as nitrosamines, polycyclic aromatic hydrocarbons, etc., these substances can be formed in water under specific conditions, and have strong carcinogenicity.
4. How to avoid ingesting carcinogenic water.
To avoid ingesting carcinogenic water, we need to pay attention to the following:
1.Try to choose clean drinking water: after drinking.
Purifying and disinfecting treated water can effectively reduce the content of harmful substances in the water.
2.Be aware of water sources: Try to avoid using water sources that may be contaminated, such as rivers, lakes, etc. Choosing a clean, reliable source of water is key.
3.Use a water filter: A water filter can effectively remove harmful substances from the water and improve the safety of drinking water. However, when using a water filter, you need to pay attention to replacing the filter element in time to ensure the effectiveness of the water filter.
4.Pay attention to personal hygiene: Before drinking water, you should clean the water cup and kettle to avoid secondary pollution. In addition, daily behaviors such as brushing teeth and washing the face may also lead to the ingestion of harmful substances due to water pollution.
5.Scientific understanding of drinking water: Correctly understand the knowledge of drinking water, do not blindly listen to rumors, and scientifically choose the drinking water that suits you.
V. Conclusions. Boiling water and overnight water are not carcinogenic, and the real carcinogenic water is water that contains specific harmful substances.
