1, scale are a mix of heavy metals in the water, calcium salt, dust, bacteria, such as eggs body of sediment, not only health, but also seriously affected the health of human body.
According to chemical analysis, 1 gram scale contain lead about 12 micrograms in 44 micrograms, 21 micrograms of arsenic, mercury, cadmium. 3.
4 micrograms, 24 micrograms of chemical material such as iron.
2, due to the scale of the presence of large amounts of heavy metals, long-term intake of heavy metal poisoning can cause the human body, with many heavy metals can cause cancer in human organs.
Scale affect human body health, easy to cause gastrointestinal digestion and absorption function disorder and constipation, increase the incidence of gastritis and all kinds of stones.
Dental calculus, periodontal disease is often caused by scale;
3, scale does not dissolve in water is relative, and there is part of the precipitate dissolve after water is heated, it will put the formation of precipitation of heavy metal ions into the water again, make the content of heavy metal ions in the water more than the requirements of health standard, endanger human body health, such as calcium carbonate, magnesium carbonate in the body of sedimentary stone formation.
4, scale hidden more hidden trouble, with water containing the scale face and take a bath, will form the calcium magnesium soap, it is like glue, sticky, stick on the face, skin, and make the dirt is not easy to get rid of.
Wash and blocking skin gland openings, dirt not embolize, affect the normal metabolism, make the shrinking premature aging of the skin.
