Limescale — a killer of human health 1Experts conducted a chemical analysis of the scale of boiling water stored in a 5-pound thermos for 18 days and found that it contained a variety of harmful heavy metal substances, namely cadmium 0,034 mg, lead 0 12 mg, iron 24 mg, arsenic 0 21 mg, and mercury micrograms. This shows that even if the drinking water meets the hygienic standards, after being stored in a thermos, trace metal elements can precipitate and accumulate in the water, which is harmful to human health.
The potential health hazards are even more serious if it is drinking water that does not meet sanitary standards. Therefore, limescale must be removed regularly.
2.When using scale utensils to fill acidic liquids such as sour plum soup and beer, some heavy metal elements precipitated in the scale will undergo a chemical reaction and re-dissolve in water or other liquids, and when people ingest a small amount of water for a long time, it can cause lesions and dysfunctions of the human digestive, nervous, respiratory and hematopoietic systems, causing serious harm to human health. So don't underestimate this scale.
3.After the scale suspended in the water is drunk by us, it will precipitate in the body, which can easily lead to an increase in the incidence of kidney stones, urethral stones and other diseases.
4.Limescale is the real culprit of common oral diseases such as tartar and periodontitis.
5.Limescale hides legionnaires, which are still unpreventable by vaccines, and which kill 2,000 to 3,000 people in our country every year.

Burn it directly on the microwave, heat it up, knock it and it comes down.

The alkalinity of water is mainly due to the excessive content of magnesium carbonate and calcium carbonate, which is insoluble in water and will form precipitation, and eating too much will cause kidney stones. Or leave it for a few days and wait for them to settle before eating, and the harm will be greatly reduced.
When tap water is boiled for three minutes, the toxic substances in it can be degraded to a minimum, and this water is the best water for people to drink. Cooking with boiling water can prevent most of the calcium carbonate, magnesium carbonate and mercury, copper, lead, god and other harmful substances in the water from entering the human body, reduce the incidence of stone disease and chronic poisoning, and also prevent the chlorine contained in tap water from destroying the vitamins in the grain when cooking. 1. Descale with vinegar or beerAdd some vinegar or beer to the kettle and shake and rotate it to dissolve the scale attached to the wall of the kettle.
2. Thick rice soup and noodle soup that have become sour by natural fermentation can also be put into a kettle to remove the scale attached to it.
3. Put the tea leaves in the kettle and pour boiling water to soak to remove the scale. 4. Wrap a small ball of absorbent cotton with gauze with cotton ball or melon to inhibit scale, or use a loofah with peeled seeds, and put it in the pot when boiling water, and the scale will adhere to it.

The water is alkaline, how to remove it? If you want to remove the alkalinity of tap water, you need to install a water purifier, and you can change it by using a water purifier.

If the tap water is alkaline, you can put some rocks to check and magazines.

Refers to limescale in tap water.
Scale refers to the white lumpy or powdery substance gradually formed by the mineral contained in hard water after boiling in the container (such as pot, kettle, etc.), the main components are calcium carbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc. The thermal conductivity of scale is very poor, if the scale formed in the boiler is too thick, it will lead to a decrease in the efficiency of the boiler, and in the worst case, it will cause the boiler to burst and cause a boiler accident.
When water is combined with carbon dioxide to form a trace amount of carbonic acid, the water dissolves better. As water flows through land and rocks, it dissolves small amounts of minerals, calcium and magnesium are two of the most common components, which harden the water. The more mineral components such as calcium and magnesium are in the water, the harder the water will be.
Heating the water, decreasing the water pressure (e.g., turning on the faucet), adding chemicals to the water, etc., can lead to an increase in pH. As the pH value increases, the ability of water to dissolve minerals decreases, and these minerals (mainly calcium carbonate) precipitate out and become limescale.
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. >>>More
1.Limescale after boiling tap water is generally harmless to humans. >>>More
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.
Whether these objects are harmful to our health or not, with this question, we can only really figure it out after checking some information! It is impossible to filter out all the impurities and contaminants in it, and the residual impurities and contaminants are still a potential threat, so people are not very confident about it. Moreover, most of the components of these scales are calcium carbonate and magnesium carbonate, and too much calcium enters the body and enters the kidneys, which will slowly precipitate, and periodontitis is often caused by scale; It can kill people. >>>More
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
