2. Water is an indispensable foundation for everyone. Without water, there is no life. However, with the development trend of the times, the safety of drinking water cannot be guaranteed more and more. The tap water that everyone uses every day is even exposed to "lead water" that may be polluted by the environment of fake faucets and water supply pipes. How to improve the health index of drinking water in daily life to deal with such difficulties?
The lead in most faucets exceeds the standard 1. Recently, a comparative experiment was carried out on faucet products on the market, and it was found that 22% of the samples were found to have lead exceeding the standard, and some products exceeded the standard by 20 times.
2. Researchers randomly selected 50 kinds of faucet products in various home building materials markets and shopping malls, and authorized relevant departments to conduct inspection. The data show that only two stainless steel plates have no heavy metal precipitation during the lead precipitation concentration detection at 10 hour and 24 hours.
Faucet-water supply pipeline, tap water pollutant 1, tap water environmental pollution comes from: water pollution and secondary pollution in the whole process of water supply. At present, most faucets used at home are made of alloy copper, the main components are copper and zinc, and there are also elements such as lead, aluminum, tin, iron and manganese. Among them, lead will precipitate after long-term contact with water, so the more lead content in faucet materials, the greater the lead precipitated.
2. In addition to faucets, water supply pipes such as cast iron drainage pipes and air-conditioning copper pipes also contain more or less lead. Water supply pipes made of this material will also cause environmental pollution of tap water.
The harm of lead to human body is 1. Lead is a heavy metal element that seriously threatens health. Symptoms of lead poisoning in adults often lead to fatigue, depression, heart failure, lower abdominal pain, kidney deficiency and other diseases.
2. If the human body suffers from lead pollution for a long time, it will continue to cause iron deficiency anemia, nerve damage in limbs, abnormal hair filling of human bones and muscle fibers, a decrease in the total number of male sperm, and high lead content in blood will also cause serious harm such as hypertension and osteoporosis. Children and pregnant women are the biggest victims. Very low levels of lead exposure can lead to children's abnormal personal behaviors, such as inattention, inattention, decreased self-study ability, irritability, and strong offensive ability. In addition, lead pollution will also cause great harm to pregnant mothers, increasing the probability of miscarriage, premature delivery, placental abruption and stillbirth.
How to safely eat tap water? How can we avoid lead-containing water when dealing with water-collecting articles that are indispensable for daily life? Experts believe that the following six points should be guaranteed:
1, don't drink overnight water.
The test statistics of the lead precipitation concentration value of the faucet show that the longer the water stays in the faucet, the higher the lead content, so the water in the faucet should never be drunk overnight. If you encounter a notice of water cut-off, it only takes more than 6 hours. Before use, you must turn on the tap and add water 1-3 minutes before taking it.
2. Don't take warm water for a long time.
At present, many residential quarters supply boiled water 24 hours a day, but try not to use it as domestic water or for cooking, because the lead content in water is many times higher than that of ordinary cold water.
3. Don't buy fake faucets.
When purchasing faucets, you must choose qualified products, preferably metal faucets. Because stainless steel material does not contain lead, it is not easy to produce secondary pollution. You can also choose faucets with low lead or without heavy metals, and now some institutions have developed such new technology products.
4. Immediately observe the water transformation of domestic water.
First of all, observe the color of the water to see if it is abnormal or turbid, and if there are dirty things; The second is to smell whether the water has peculiar smell, such as fishy smell, metallic substance smell and grass green smell.
5. Add water before drinking water.
Before drinking tap water, turn on the tap water and let the water run for a while. This also applies to the morning when parallel mobile phones have not used tap water for a long time. The discharged water does not need to be wasted and can be used for daily cleaning.
6, environmental pollution sewage treatment
Environmental pollution water does not need to be eaten immediately, but must be boiled. When the water boils to close to 100 degree, open the lid of the teapot to volatilize the pollutants in the water. You can also store water naturally and eat it after removing the chemicals in the colloidal solution in water.
7, dirt should be removed regularly.
Although there is no harm to physical and mental health, it is good to be dirty and inconvenient.
If the water body in an area is solid, the equipment for conveying and heating warm water will be very easy to scale, which will lead to low efficiency and even common faults of tap water equipment, shorten the service life of equipment and greatly increase energy consumption.
For the daily theme activities at home, the hardness of water will consume a lot of water and washing supplies when cleaning, and clothes are not easy to clean and their service life will be shortened. Bathing with water hardness can also cause damage to skin and hair.
8. Drink some weakly alkaline pure water.
What is weakly alkaline water, because there are quite a lot of alkaline earth metal cations in water, and then water is alkaline. What are the benefits to the physical and mental health of the human body? Because alkalinity is the source of all diseases, all normal ph values of the body are between 7.35 and 7.45. When the PH value is lower than 7, people will get sick and die. In everyone's daily life, people who are less ill and healthy account for 10%, and their constitution is alkaline; 90% of human body is sour. Among them, 10% is seriously ill and 80% is sub-healthy.
Foods containing phosphorus, chlorine, sulfur, sulfur and other elements are generally acidic foods, such as wheat flour, meat food, cereals, vegetable oil, beverages, carbonated beverages, sugar and so on. Potassium, sodium, calcium, magnesium and other elements are generally alkaline foods, such as fresh fruits, vegetables and fruits, beans, dairy products, laver, alkaline drinks and so on. It must be emphasized that foods with strange smell are not necessarily acidic foods. Take oranges as an example. They are alkaline foods because they contain enough potassium. Professor He, an expert from Sun Yat-sen University (formerly Sun Yat-sen Medical University), made it clear. The ratio of people who eat acidic and alkaline food should be: acidic fruit 1: alkaline food 3. Brand image: Eat 1 serving of white rice, and only eat 3 servings of fruits and vegetables to get a balance. But everyone's daily life is unlikely to guarantee this. Therefore, eating more alkaline food and weakly alkaline water has a good promotion effect on alkaline groups.
Authoritative expert who want to drink Albin healthy water or improve that pow supply equipment of municipal engineering mentioned that standard tap water is the safest and most reliable in term of everyone's professional skills. Naturally, it is ok to drink pure water in a short time due to the needs of going out, traveling on holiday, meeting, etc. However, there are many new types of water on the market at this stage, including acidic water, alkaline water, purified water, pulse water, etc ... From the point of daily consumption, it is not strongly recommended to eat, including mineral water, because its ion concentration is too low, and long-term consumption is not good for the body. Therefore, the key to improve the water body is to maintain water resources, improve the power supply equipment of municipal engineering and further improve the power supply water body of municipal engineering.
