The earth is rich in water resources, but there is not much water to drink, most of which is seawater. Why can't sea water be drunk? Here to give you a simple analysis, I hope to help you.
Why can't sea water be drunk
Because 2113 in seawater contains a large amount of salts and various 5261 elements, the concentration of various substances in seawater is too high, which far exceeds the 4102 drinking water hygiene standard. For example, drinking a large amount of 1653 fruits will lead to excessive entry of some elements into the human body, affect the normal physiological function of the human body, and even cause poisoning in serious cases.
Sea water is water in or from the sea. Sea water is flowing. For human beings, the amount of water available is unlimited. Seawater is a real liquid mineral, with an average of 35.7 million tons of minerals per cubic kilometer of seawater. 80% of the more than 100 elements known in the world can be found in seawater.
What are the hazards of drinking seawater directly
Boil the sea water in the container full of sea water with a fire until the sea water in the container is completely evaporated. At this time, we will find that there are many experiments of small particles in the container without sea water. Of course, this is not the salt we usually eat. There are many minerals in the remaining salt after evaporation, which can only be eaten after purification through many processes.
If we drink sea water directly or use sea water to replace salt directly, it will not only make a great difference in taste, but also ingest many minerals harmful to our human body, which is one of the reasons why sea water can not be eaten directly. We can only drink these sea water after desalination by special means.
In addition, due to environmental pollution in recent years, marine resources have also been greatly polluted. A lot of garbage has been discharged into the ocean, which can not be purified in a short time, so this is one of the reasons why seawater can not be eaten directly.
