Article 6 the indicator of health drinking water must comply with

It is reported, the world health organization ( 世卫组织) Proposed six healthy drinking water must meet the following requirements: six,

a removal of the harmful material life

there are a lot of water biological and physical harm to body health. Such as residual chlorine in tap water, conduit pipe scale, very long time can cause serious diseases of heavy metals, infectious diseases caused by bacteria, chemical damage to human body, residual chlorine, carcinogenic trichloromethane, deadly toxic pesticides. Drinking water and domestic water should not have these substances.

2, the balance of minerals

healthy balance of water containing minerals and trace elements, the body's metabolism which require the participation of minerals. About 18 kinds of essential minerals, to maintain the health of human body and adjust function of the body, calcium, iodine, iron, magnesium, phosphorus, zinc and other minerals.

3, PH value of a weak alkaline

human body fluids for PH 7. 35 - 7. 65 is weak alkaline, body fluids, if serious bias strongly acidic, must be sick. Acid liquid is a hotbed of cancer cells to breed. Weak alkaline water is healthy water, absorbing the weak alkaline water, is the body metabolism becomes more smooth, more lively life activity function.

4, water hardness appropriate ( The content of calcium and magnesium ions) appropriate

healthy water calcium and magnesium content in a proper level, contain appropriate calcium and magnesium ions in drinking water can reduce the incidence of cardiovascular disease. Calcium is one of the human body essential trace element, magnesium can resist the calculus of human body. Life is about 900000 liters of water. Every day from drinking water intake is about 200 mg of calcium content, about a third of the human body needs calcium every day, drinking water is one of the important way to calcium intake of the body. Bones are the vault of the calcium, the body organs lack calcium, is extracted from the bones, adults every day at least one thousand milligrams of calcium intake, if long-term lack of calcium in the human body, gradient fragile bones. Five moderately, oxygen and carbon dioxide into the

water solubility, water contact with the atmosphere, integration of the necessary oxygen and carbon dioxide, water heating for oxygen and carbon dioxide disappear, canned or sealed environment for a long time to save water, the oxygen and carbon dioxide will not be too high. Hypoxia state of water quality, cannot be activated water, carbon dioxide is to determine the element of water taste, rich in dissolved oxygen in water is not easy to breed bacteria and algae, and can improve the activity of water. Six, small molecular group water

using nuclear magnetic resonance device can observe nature water molecules moving speed, on the basis of observation, close to five the number of water molecules into water molecules of water, water molecules group, the smaller the solvency, penetration, and the stronger the ability to metabolize.

water is an important part of life, water quality directly affects the body, pay attention to drinking water safety, protection of water resources is related to the future of our country.
