9. Every year, 25 million children in the world get sick and die from drinking polluted water.
mineral water
According to China people's national standard GB8537-2008 "Drinking Natural Mineral Water", the definition of mineral water is: "Water that naturally gushes from deep underground or is collected by drilling, contains a certain amount of minerals, trace elements or other components, and is not polluted in a certain area and preventive measures are taken to avoid pollution; Under normal circumstances, its dynamic indicators such as chemical composition, flow rate and water temperature are relatively stable within the fluctuation range of natural circulation. "
The national standard stipulates 57 water quality indexes that mineral water must be tested. After more than one year's observation, mineral water can be officially named as mineral water only after it has been examined and identified by the expert group and registered by the competent department of geology and mineral resources.
How are mineral springs formed?
Mineral water is a valuable mineral resource. Only under the special geological structure and hydrogeological conditions, after a long geological age, under the environment of high temperature and high pressure, through the comprehensive action of natural purification, leaching and ion exchange enrichment, minerals and trace elements in surrounding rocks can be transferred into water, and qualified mineral water can be formed.
Is mineral water healthy water?
Modern scientific research has found that residents who drink mineral water for a long time have significantly lower prevalence of certain diseases than locals who drink other water sources, and their growth and development indicators have improved and their average life expectancy has been prolonged. The fundamental reason is that mineral water meets the following conditions of healthy water:
Mineral water is deep groundwater, pollution-free, free of pathogenic bacteria and microorganisms, and free of harmful substances.
Mineral water is rich in calcium and magnesium ions with moderate hardness.
Mineral water is weakly alkaline, and the PH value is mostly in the range of 7-8.5.
Mineral water contains a certain amount of dissolved total solids.
In addition, mineral water also contains some essential trace elements, which is very beneficial to health. So mineral water is the best category in healthy water.
What's the difference between pure water, mineral water, natural spring water and mountain spring water? And mineral water?
Pure water: water that can be directly drunk by distillation, deionization and reverse osmosis. It contains no additives, is acidic soft water, contains no nutrients, and is easy to dissolve and discharge beneficial trace elements from human body.
Mineral water: it is a man-made industrial product made by adding a proper amount of synthetic mineral salts to drinking pure water. In most cases, there are only major elements such as potassium, sodium, calcium and magnesium, and there are generally no trace elements.
2065438+In March 2004, the General Office of the National Health and Family Planning Commission recently published the draft of "National Standard for Drinking Water in Food Safety Packaging", proposing that the name "mineral water" should not be used to mislead consumers. Mineral water is actually artificial addition of food additives to tap water, not real mineral water.
Natural spring water, mountain spring water: mainly used for enterprises in commodity naming. * * * is characterized by clear water from underground, containing a certain amount of minerals and trace elements, and its dynamic index is relatively stable. However, its characteristic components did not reach the limit index of mineral water.
Mineral water: The formation conditions are harsh, the national standards are strict, it is rich in nutrients and trace elements beneficial to human body, and it is completely natural and healthy, ranking first among all kinds of drinking water.
