Analysis:
Water is the most important component in human body composition, accounting for 70% of the total mass of human body, and it is an essential nutrient carrier for human body.
With the development of society and the enhancement of people's health awareness, people pay more and more attention to drinking water hygiene because it is closely related to people's health.
Let's pay attention to whether the tap water around us has the following hidden dangers.
Is the residential water tower covered with moss, and is there the possibility of dead rats and cockroaches?
I just turned on the water pipe this morning. Did you find that the water is yellow and smells like rust?
Is the water pipe rusted, corroded and broken, and infiltrated by underground sewage?
Is it possible that the source of tap water we drink is polluted by toxic industrial products, pesticides, detergents and water sources?
Are there any exhaust gases from industries, automobiles and locomotives that pollute the air in our natural environment, or may form toxic groundwater through rainwater?
Tap water should be a convenient and safe drinking water, but with the progress of material civilization, more polluted media are produced, so drinking water incidents occur unconsciously and affect human health. Once people drink polluted water, the wastes, toxins and heavy metals in it will accumulate over time and be stored in people's bodies. In the end, many a mickle makes a mickle, which does harm to people.
Let's take a look at the possible pollution in tap water. Tap water is a comprehensive liquid, and there are many invisible impurities besides water. It may include dozens of pesticides, chlorides, organic carcinogens, bacteria, viruses, radioactive particles, molds, pesticides, sodium salts, calcium and magnesium, nitrite and inorganic solutes, asbestos fibers, arsenic, cadmium and harmful heavy metals. These may be the causes of stones, bone, nerve, skin and viscera damage, Blackfoot disease, deformed children, mental disorder, insomnia, dizziness, headache, joint pain, digestive and urinary system diseases and cancer. Drinking poor quality water for a long time will definitely worsen your health.
In order to prevent bacteria in water, the waterworks add chlorine in the water treatment process. Recently, however, scientists have found that after chlorine is added to water, it will combine with organic substances in water to produce trihalomethane, a carcinogen. The dirtier the water is, the more chlorine is added, and the more trihalomethane is produced. This compound cannot be removed by boiling. It can cause liver cancer, intestinal cancer and bladder cancer, which is deeper, bigger and more terrible than safrole.
