Do not use glass for a long time to bloom acidic drinks
Glass is divided into crystal glass, glass office cups, glass mug, tail glass, no tail glass. A tail cup is not a vacuum cup holding time is short. No tail cup is a vacuum cup for a long time. Glasses are divided into ordinary glass and crystal glass, which have two kinds of glass and lead-free glass and leaded glass. Lead-free glass is the best cup of healthy drinking water, and lead crystal glass
In daily life, lead-containing artificial crystal cups containing alcohol, cola, honey and acid-containing fruit juice and other acidic beverages or other acidic foods, lead ions may form soluble lead salts with the beverage or Food intake by the human body, a serious health hazard.
According to Professor Zhu Qichang, lead and more in the form of free state or inorganic compounds through the blood-brain barrier, the blood vessels of the central nervous system - the hippocampus and cerebral cortex harm. When the blood lead concentration of 30 micrograms / liter, there will be generalized fatigue, dizziness, headache, anemia, memory loss, muscle and joint pain, constipation, female menstrual disorders and other neurotoxic reactions. Arteriosclerosis, peptic ulcer and fundus hemorrhage and other symptoms are also related to lead pollution. In high blood lead levels, the patient has a metallic taste in the mouth, the patient's intravascular water infiltration into the brain interstitial brain edema can lead to cerebral hemorrhage, demyelinating lesions and other pathological changes. When the long-term intake of lead and its compounds, the excess lead will be deposited in the bones, buried fracture risk.
However, the early lead poisoning is often difficult to find, especially the long-term use of lead-containing glassware drinking acidic drinks, as well as long-term chronic poisoning, but no obvious history of exposure to lead was misdiagnosed. Professor Zhu Qizhang suggested that people in their daily lives, the use of lead-free glassware should be avoided when filled with acidic beverages or food, it is best to use ordinary glass. Conditions permit, the use of lead-free crystal glass as a glass and kitchen utensils, so that more secure and reliable. For the sake of health, I hope you do not use glass containers for a long time in full bloom acidic drinks.
(hereinafter referred to as Crystal Cup) is the most adverse to human health cup, often in some small supermarkets and stalls on the most common. Recently, Sichuan University, West Fourth Hospital, Professor Zhu Qizhang, crystal glass should not be filled with acidic beverages, if the long-term use of such cups filled with acidic beverages easily lead to poisoning.
Currently on the market flow of the crystal cup in two: lead-free crystal glass and lead-containing crystal glass. The latter generally contain potassium, mostly high-end handicrafts and logo on the outer packaging, mainly as a glass; the latter is lead, that is, in some supermarkets and stalls on the common crystal glassware, the content of lead oxide up to 24% .
