Is the scale in tap water harmful to people s bodies?

The kettle boiling water has a white-yellow rust. I never drink this water, I go to the mountain water plant to use the car, and I come back with a bucket to drink, there is no rust at all, there is no scale, I use water for cooking, and press the filter. There is such a big harm as rust, for your health, only find a way to contain a lot of calcium in the human body to produce stone disease, gastritis, etc., if the calcium content in the blood is too high, it will lead to muscle weakness.

We use utensils containing limescale to hold acidic liquids, such as sour plum soup, vinegar, etc., or use utensils containing limescale to boil water, cooking, etc., but if you use the water in the pipes with rust for a long time.

Then this is harmful to the body, so pay more attention to yourself in ordinary times, and never drink water with rust, which may contain heavy metals, and long-term drinking is not good for the body at all. The formation of scale is a complex physical and chemical change process, natural water often contains calcium sulfate and magnesium sulfate, carbonate, silicate and other impurities, after heating, the structure of the impurities contained in the impurity changes, becomes insoluble in water precipitate and accumulates, the formation of scale.

Whether it is harmful to the human body, it is necessary to analyze the composition of scale. Limescale does not dissolve when exposed to cold water, but partially dissolves when heated. After dissolving, heavy metal ions will seep into the water, which will make the heavy metal ions in the water exceed the standard, and some of the precipitates will be dissolved after heating beyond the normal water, which will form the precipitation of heavy metals from the School of Public HealthProfessor of Environmental Toxicology Wu Zhigang explained that the scale is calcium carbonate and magnesium carbonate, which are the precipitates of calcium ions and magnesium ions in the water after heating.

CCTV also has a program for the harm of tap water scale to the body, the answer is that the water that meets the standard is brought back into the water, so that the content of heavy metal ions in the water exceeds the requirements of health standards, endangering human health, such as calcium carbonate, magnesium carbonate in the human body a large number of deposits are easy to form hardness, that is, there are many mineral ions in the water, and the minerals in the water change from ionic to crystallized when boiling. If there is no other pollution, it is not particularly bad. This is also a "selling" point for merchants selling pure water machines to attack the tap water problem.

Generally, tap water is treated to meet the national water standard, and the scale in the water is harmless to the body, and after the scale is drunk, the stomach acid will decompose it into calcium and magnesium ions that are beneficial to the body.

The scale formed after boiling qualified tap water is harmless to the human body, so you can rest assured. If the tap water is not up to standard, then such scale may be harmful to the human body.

The scale in tap water is very harmful to the human body, because these scales in the body can not be dissolved and accumulate in the body for a long time, which is easy to make the body more garbage and the blood vessels thicker.

If you drink a small amount of calcium and magnesium in the water plant, it is still good for the human body, but if you consume too much, the body will not be able to absorb it and it will produce stones.

If these scales enter the human body, they will accumulate and remain in the human body, which will affect the health of the person in the future.

This kind of water has some harm to the body, because it cannot be absorbed by the stomach, so gallstones will eventually form in the stomach, which is very unhealthy.

The main components of limescale are calcium carbonate and some magnesium carbonate, which does not affect health. In fact, calcium and magnesium are nutrients that the human body needs, and many calcium tablets are also calcium carbonate. If there are no heavy metal ions, it is only limescale formed by calcium and magnesium ions, which has little impact on human health.

The main components of scale are calcium carbonate and magnesium carbonate. Limescale usually exists in the form of crystals, has a hard texture, and is difficult to remove once formed. Limescale has a serious harm to human health.

According to chemical analysis, there are a large number of heavy metals in scale. According to medical practice, long-term ingestion can cause heavy metal poisoning in the human body, and many heavy metals can cause carcinogenesis of human organs. Moreover, scale is insoluble in water is only relative, and some of the precipitates will dissolve after the water is heated, which will bring the heavy metal ions that form the precipitate back into the water, so that the content of heavy metal ions in the water exceeds the requirements of health standards, and endangers human health, such as calcium carbonate and magnesium carbonate are deposited in the human body in large quantities and are easy to form stones.

In addition, long-term intake of limescale is also easy to cause gastrointestinal digestion and absorption disorders and constipation, which increases the incidence of gastritis and various stones. Tartar and periodontitis are often caused by limescale.

It is easy to cause gastrointestinal digestion and absorption disorders, as well as urinary system diseases, such as constipation, etc., and in severe cases, it will also lead to gastritis and various stones such as kidney stones and urethral stones. Tartar and periodontitis are also related to scale to some extent.

Secondly, when the scale is cemented, a large number of heavy metal ions are often attached, and if the container is used to hold drinking water, there is a risk that the heavy metal ions will be dissolved too much in drinking water.

Most of the water alkali in drinking water is calcium carbonate and magnesium carbonate salt, and the rest is potassium carbonate and sodium carbonate, which are called permanent hardness, and the content is very low, and drinking has little effect.

Tap water contains limescale, which is harmful to the body. Scale is a hard deposit formed on the wall of water pipes, mainly calcium carbonate and calcium silicate, and may also contain metal ions such as iron, zinc, and aluminum. The heavy metal ions, corrosive gases and organic substances in the scale can pollute the water quality, affect the taste and taste of tap water, destroy the microbial activity in the water, and affect the hygienic quality of the water.

The heavy metal ions in limescale can also enter the human body through drinking tap water and have adverse effects on human health, especially on children and infants.

1. When the tap water is heated to 80 degrees, the calcium and magnesium ions in the water will form scale.

2. Causes of scale: tap water contains more Ca2+, Mg2+, 2HCO3-=CO32-+H2O+CO2, Ca2+CO32-=CaCO3, Mg2++2OH-=MG(OH)2, the solubility of these two substances in water is very small, so the precipitation is formed.

3. Prevention and treatment methods: the internal cause of scale is the quality of tap water, as long as the temperature exceeds 60 degrees, scale will be generated. Family life tips can be removed with baking soda, acetic acid, citric acid, eggs and potato chips.

Of course, if you want to achieve a better effect, you can install a drinking water anti-scale device on the tap that specifically removes limescale, so that the water coming out of the anti-scaling device will not be formed when it is reheated.

Drinking limescale is not very harmful, because the composition of limescale does not cause much damage to the human body.

Scale is actually a mineral salt precipitation, and the main components are calcium carbonate, calcium sulfate, magnesium hydroxide, magnesium carbonate and other water-insoluble compounds. It is related to water quality, and in hard water quality areas, as long as the saturation index in the water is not exceeded, there will be no scale. If it is below the saturation index or just at the critical point of saturation, there will be no limescale formation.

However, if the saturation index is exceeded, even soft water will produce limescale. Whereas, the saturation index is determined by the pH of the water.

The lower the pH value, the stronger the acidity in the water, the higher the saturation index, and the more mineral components can be dissolved; The higher the pH, the more alkaline the water, the lower the saturation index, and the less mineral content can be dissolved. As the pH rises, the water's ability to dissolve minerals decreases, and these minerals (calcium carbonate) precipitate, forming scale.

In other words, the presence of scale in the water indicates that it is alkaline water, and the water contains a lot of minerals, and these minerals are not harmful to the human body, so the water with limescale does not hinder drinking.
