The fact that the factory water can be drunk directly is not the same as the tap water at home, and the harmful substances in the water will affect the health of the body. Tap water must be treated as necessary before it can be used directly.
-
If you are in China, you should not drink tap water casually, but you can also drink it abroad.
-
Yes, it is not very hygienic and prone to kidney stones.
-
Do not drink tap water, unboiled tap water may contain some pathogenic microorganisms such as bacteria, viruses, parasites or eggs, etc., in addition to some harmful chemical ingredients to the human body. When drinking this unhygienic raw water, it is easy to get sick. Although the tap water in the city has been disinfected, it is impossible to be completely assured, not to mention that the tap water is disinfected with chlorine, and the tap water contains chlorine gas, which is not good for the human body, and after boiling, chloroform and carbon tetrachloride are carcinogens.
If you want to drink tap water, you should pay attention to the following 4 points:
1) The first bucket of tap water that flows out in the morning can be used as domestic water, but it is not suitable for drinking. Because this water stays in the water pipes overnight, bacteria may multiply, or a certain amount of metal elements may be dissolved from the water pipes.
2) Boiling water is generally boiled for 3 minutes, and drinking water that has not been boiled or boiled for too long is not good for the body.
3) Drinking water can be left for a few hours before boiling (but not more than a day).
4) In the world, the harmful substances of halogenated hydrocarbons in the water can not be completely avoided by chlorine disinfection water, and the body's own detoxification function can prevent the harmful substances with little content. Those who can afford to consider using a qualified activated carbon purifier to drink tap water more safely.

Tap water contains nitrosamines, mainly from industrial wastewater, nitrosamines are one of the most health-risky disinfection by-product categories, especially nitrosodimethylamine, nitrosodimethylamine is a "carcinogenic" substance, is a by-product of disinfection, these "carcinogenic" substances, are also certainly harmful to the body.
Residual microorganisms can also multiply in tap water, which contains a large number of substances that are harmful to humans, and may also harbor Legionella, an acute respiratory infectious disease that threatens human health.
-
Drinking tap water for a long time can be harmful to the body. The reason is that chlorine is generally used for tap water purification, and the residual residual chlorine will generate chloroform (narcotic, carcinogenic potential) in the heating process, which will cause great harm to the human body when consumed for a long time. Tap water refers to the water produced by the tap water treatment plant after purification and disinfection that meets the corresponding standards for people's life and production.
Domestic water is mainly absorbed from rivers, lakes, groundwater and surface water through the water intake pumping station of the water plant, which is treated by the waterworks in accordance with the relevant health standards for domestic drinking water, through precipitation, disinfection, filtration and other technological processes, and finally transported to various users through the water distribution pumping station.
-
Yes, the tap water is not boiled, there are all kinds of bacteria in it, if you drink it like this often, be careful that it is harmful to the stomach and intestines, it is recommended to drink plain water, hope, thank you, I wish you good health.
-
There are many microorganisms in the water, which can adapt to the anoxic environment in the water. If you drink raw tap water, they are carried into the stomach, causing adverse symptoms such as stomach discomfort, and in severe cases, it can also cause a series of diseases such as diarrhea and gastritis. However, under normal circumstances, there will be no major problems, but it is better to boil it before drinking it safely.
-
Tap water contains substances that are harmful to the body. Chlorine, the "biocide" in tap water, releases reactive chlorine, which chemically reacts with contaminants in the water to form a chloride. This chloride can induce bladder and rectal cancer.
Therefore, poorly treated tap water or with a high chlorine smell should not be consumed.
-
It really depends on the quality of the tap water. Because our corresponding standards are relatively relaxed, they are domestic drinking water standards, and they are not directly aimed at drinking water.
There are a few cities where tap water is of better quality, less polluted air, and can be heated and drunk. But most places don't do that. As for the specific situation of its harmful substances, you can find a lot of relevant content on the Internet.
-
Drinking tap water for a long time is harmful to the body, because there are some impurities and microorganisms in tap water, as well as some bacteria, if not filtered, long-term drinking will be harmful to health.
-
It is harmful to our body, and if we drink tap water regularly, there will be a lot of bacteria in it, which will make our stomach and intestines very comfortable.
-
It will be harmful to the body, tap water will cause malnutrition and will also take away useful trace elements in the human body, reduce the body's immunity, and make it easy to get sick.
-
Drinking tap water is not harmful to our body, but we must boil the tap water and drink plain water, which is better for the body.
-
Some buildings are afraid that the water pressure is not high or there is a temporary shortage of water, and the water is stored in the water tank on the roof, and then the water is supplied to the residents, if the safety of the water tank itself is not good, then the quality of drinking water for the residents is difficult to guarantee. In fact, chlorination byproducts are divided into volatile and non-volatile. Whether exposed to drinking water or cooking food, the lifetime carcinogenic risk of long-term consumption of chlorinated water is less than one million, which is within the acceptable risk range.
In general, the acceptable lifetime risk of cancer is less than: Most of China's waterworks meet national standards for water quality, and the only link that can affect water quality is the yellow water caused by the corroded pipes when the tap water is delivered to the user's home.
Water pipes mostly use random polypropylene and other aluminum-plastic pipes, which generally do not release metal, but the materials of household faucets are varied, from corrosion-resistant turbidity, non-exudable, lead-free stainless steel faucets to cheap iron faucets, there is indeed the possibility of heavy metals in the water. But a study by a professor at Shanghai Jiao Tong University found that the metal content in tap water is well below the national limit and poses no health risk. Generally, tap water is drinkable, but don't drink tap water directly, try to boil it before drinking, there will be pollution in the water tank.
Because the aging of the water pipes will also lead to the deterioration of the quality of tap water, drinking it after boiling can play a role in disinfection. If you drink tap water directly for a long time, it can easily cause stone disease, such as gallstones or urinary stones. Therefore, tap water is not as dangerous as imagined, and long-term drinking will not cause great health effects, so you can drink it with confidence.
The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Harmful. Because there are many bacteria, fungi, dust and other impurities in tap water, when the human body drinks it for a long time, the body's immunity decreases, and you may get sick. Therefore, it is recommended to boil tap water and drink it cool.
-
Of course, it is harmful, because the tap water has not undergone any treatment, so as to avoid a lot of bacteria and precipitation, which will cause unhealthy health and stones in the body.
-
When I was a child, I grew up drinking tap water in my hometown. Hold the faucet and drink directly from mouth to mouth. Now I'm also thinking about this, I can't drink the tap water, I can't breathe the air outside, and I have to bring a broken mask.
You also need to wear a helmet when riding a bike. Just ask pedestrians to put on hard hats and body armor. You also need to wear glasses when playing with a mobile phone, for fear of radiation.
-
Mainly some chemical residues, which may cause harm to the body and body organs. Because it takes a lot of effort for the human body to metabolize them... The worse the body, the worse the ability to degrade toxins.
-
It should be said that it is not necessarily right for the benevolent to see the benevolent and the wise to see the wise. Why? I grew up drinking tap water directly, I can say that I have drunk at least 3o for more than 3o years, and now I am more than 5o, and my body has always been very good, especially the internal parts, which are better than imported young people.
I don't want to talk about it, so please judge it.
-
Yes, hypochlorous acid may be high in the body, and the frequency of urination and diarrhea is more frequent.
-
I've drunk tap water for most of my life, and now it's very healthy, nothing is absolute, unless I drink polluted water, it's hard to say, so it's better to install a water purifier for drinking safety, I have to say that the current tap water trust is too low.
-
In the long term, there may be effects on bacteria in unboiled water, and there may even be invisible insect eggs.
-
It depends on the water quality, and bad water quality will definitely have an impact.

No, the human body has a strong resistance to the invasion of external bacterial diseases and viruses, oral objects, drinking water, will pass through the digestive tract, and the human digestive tract has a mucosal barrier, gastric acid can kill most of the bacteria, if it is really affected, it may cause changes in the intestinal bacterial flora, thereby causing foodborne diarrhea. That's it. You won't get hepatitis B, you won't get AIDS.
But you can get hepatitis A, you can get cholera, you can get parasitic diseases. Of course, these diseases are relatively rare at present, and whether you can get these diseases depends on whether the water you drink is contaminated by these pathogens. Generally speaking, the water in the waterworks is to be disinfected, with sodium hypochlorite.
So don't worry too much. If you are really not at ease, go to the hospital to check these infectious diseases, and if you can rule them out, you will be fine.
-
The water produced by the waterworks is drinkable. However, this does not indicate that it is standard drinking water.
Although the use of chlorine to purify the water in the production process of tap water can kill harmful substances such as pathogenic microorganisms, the addition of chlorine itself can cause new chemical pollution. Chlorine can be combined with organic matter in water to form chloroform, which is a carcinogen. At the same time, chlorine also destroys nutrients and can easily lead to heart disease.
Dangers of drinking tap water directly.
In the pipe network of tap water, long-distance pipeline transportation, old and rusty pipes, urban high-rise water tanks and building reservoirs are not clean or used all year round without disinfection, which can cause secondary pollution. Secondary pollution causes bacteria, viruses and algae to multiply, plus the original chlorine and chloride, rust, heavy metals, radioactive substances, make the water turbid, have a peculiar smell, and its harm is endless.
It is recommended that you do not drink it. Unboiled tap water may contain pathogenic microorganisms such as bacteria, viruses, parasites or eggs, as well as some harmful chemicals. When drinking this unhygienic raw water, it is easy to get sick. >>>More
That's right.
Take Korla. In urban areas, for example, the urban household meter renovation project "one meter per household, water meter out of the house, meter reading to the household", for a family (a house) to install a ** settlement water meter in the outdoor public part of the residence, by the urban public water supply enterprises and residents to sign a water supply contract and according to the household meter, charge the renovation project. The scope of the urban household meter renovation project starts from the water supply main of the public water supply enterprise, and passes through the courtyard, the metering meter outside the residential building, and the outdoor pipeline to the residential building. >>>More
Dissolve into the air The tap water is white because it contains a lot of air, when the tap water circulates in the water pipe, the air in the water pipe will gradually dissolve in the tap water, and then the pressure of the tap water becomes smaller when it flows out, and the air overflows from the tap water, which can appear white. >>>More
No. Unboiled tap water is the least hygienic and unsafe. Tap water is mainly taken from river water, lake water or other groundwater, the factory purifies and disinfects it directly for people's daily use, unboiled tap water contains chlorine gas for disinfection and sterilization, affecting the taste, and because of the long transmission pipeline, the health quality is not guaranteed, so it is recommended that the dog still do not drink, drink less is better. >>>More
Tap water contains more soluble minerals such as calcium and magnesium, and is alkaline. Long-term watering with tap water will cause soil acidity and alkalinity imbalance, soil compaction, and poor air permeability, which is not conducive to the growth of plants. At the same time, tap water also contains a small amount of chlorine. >>>More
