Urine stone, gallstone these calculous disease have 90% because drank unhealthy tap water to cause, city tap water is disinfected basically those who use is residual chlorine disinfect, although be opposite on certain level the bacterium of water and virus purify action, but long-term drinkable the water that contains residual chlorine also has different level harm to human body.
Many people still think that tap water is the best water, but this is not true, because tap water does not balance the ph of the human body, and the main disinfectant in the production process of tap water is bleach, namely chlorine ion.
What is more important is that tap water is delivered to our homes through pipes after treatment. Therefore, there are serious secondary pollution such as excessive heavy metal in metal pipes, which will have a great impact on human body.
Tap water to human body harm is very big, but the life of people is inseparable from the water, such as to use it to wash my face, brush your teeth, cooking, washing clothes and so on, is everyone indispensable things in daily life, but with a lot of heavy industry, agriculture, chemical products, such as for river pollution, also said to tap water is also affected, so remember to drink tap water, drink boiling water, cannot drink water, or those harmful substances will directly to your body.
How many harmful substances are there in tap water that you can't see
1. Heavy metal pollution such as rust, lead and arsenic
Under the condition that the tap water flowing from the water plant is not completely processed, it will pass through the dense municipal pipelines, especially the old ones, which will be corroded over time. It is easy to cause the secondary pollution of heavy metals, etc. Some copper faucets will also produce lead pollution due to the limitations of the production process.
Drinking such polluted water can damage the body's liver.
2. Water pipe leakage and pollution
But in the pipeline transmission process, because each branch pipe has a large number of pumps pumping water, often cause negative pressure inside the pipe, underground sewage is likely to infiltrate into the pipe, pollution to the tap water inside the pipe.
If there are hospitals, farms, garbage dumps, sewage ponds, etc. around the broken pipes, it is inevitable that sewage will seep into the pipes. In addition, the pipe network design of some cities is not scientific, natural gas pipeline, tap water pipeline, sewage pipe and other complex, easy to leak and pollution.
3, microbial colloid, bacteria and other pollution
Because some campus floor is high, tap water can not reach the high-rise, had to build water tank on the roof, and then use booster pump to water tank, and a lot of high-rise buildings storage tank for a long time not effective clean is easy to breed bacteria, red insects, especially in the hot, salty season, the problem is more serious.
