drink tea after tea is not cleaned and the life is not cleaned. (data map)
[b] is the most easy to form tea scale [/b]
Science Research Research shows that drinking water contains minerals and trace harmful heavy metal ions, such as cadmium, mercury and arsenic. When the water is heated, the solubility of some calcium and magnesium ions decreases with the increase of water temperature, and the concentration of refractory salts is increasing. When the water is concentrated to a certain extent, the precipitation is precipitated. These precipitates can come into the tea cup with the water washed tea and are not exposed to the air. The tea polyphenols and the metal elements in the tea rust in the tea will oxidize, produce brown tea rust, commonly known as tea scale, attach to the inner wall of the cup, and contain a lot of cadmium, lead, mercury and arsenic in the tea rust. Harmful metals are the main causes of human health.

[b] for a long time not covered with tea scale can cause cancer [/b]
Li Hongzhu, vice professor of the Tianjin Medicine Research Institute, said in an interview: "in the tea scale. Contains cadmium, lead, mercury, arsenic and other toxic substances and nitrite carcinogens, these substances will adhere to the surface of a smooth cup. As the tea enters the body's digestive system, it combines with protein, fatty acid and vitamins in the food to produce insoluble precipitates, which not only hinders the absorption and digestion of these nutrients, but also damages the intestines and stomach organs. In addition, often do not wash tea cups, there are still more scale, which also contains a large number of heavy metals, which is extremely detrimental to health. At the same time, these oxides will also cause nerve, digestive, and urinary system disorders and dysfunction, even cause premature aging, especially arsenic and cadmium can cause cancer, cause fetal malformation and harm health.
