Glass into crystal glass, glass office cup, glass cup, glass has a tail, no tail glass. There are not a cup tail vacuum cup holding time is short. No tail vacuum cup cup is a long holding time. Glass is divided into ordinary glass and crystal glass, both of which have lead-free glass and glass leaded glass. Regular unleaded glass healthy drinking water is the best cup, lead crystal glass (hereinafter referred to as Crystal Cup) is the most detrimental to human health cup, most often see in some small supermarkets and stall. Recently, Professor Zhu Sichuan University Huaxi Hospital, said fourth, crystal glasses containing acidic beverages should not be, if long-term use of this cup containing acidic beverages easily lead poisoning.
Currently on the market circulation crystal cup in two ways: lead-free crystal glass and lead crystal glass. The former general potassium, mostly for high-end products and the packaging has a logo, use primarily as a glass; the latter lead, that is, in some supermarkets and stall common crystal glassware, lead oxide in an amount up to 24% .
In everyday life, if leaded glass artificial crystal made of full bloom wine, cola, honey and fruit juice containing acid and other acidic drinks or other acidic foods may lead ions form soluble lead salt with drinks or food was ingested, a serious health hazard.
According to Professor Zhu Qishang speaking, lead to more free form or in the form of inorganic compounds through the blood-brain barrier, vascular rich central nervous system - the hippocampus and cerebral cortex harm. When the blood lead levels of 30 micrograms / liter, there will be generalized weakness, dizziness, headache, anemia, memory loss, muscle and joint pain and neurological toxicity, constipation, irregular menstruation and other female. Arteriosclerosis, peptic ulcers and retinal bleeding and other symptoms are also related to lead contamination. High blood lead levels, the patient has a metallic taste in the mouth, in patients with intravascular penetration of moisture between the brain matter will lead to cerebral edema and cerebral hemorrhage, demyelinating disease and other pathological changes. When long-term exposure to lead and its compounds, an excess of lead will be deposited in the skeleton, buried fracture risk.
However, the early lead poisoning is often difficult to detect, especially long-term use of leaded glass drinking acidic beverages, as well as causing long-term chronic poisoning, because no significant history of exposure to lead and be misdiagnosed. Professor Zhu Qishang recommends people use leaded glassware in their daily lives and should be avoided in full bloom acidic drinks or food, it is best to use ordinary glass. Conditions permit, the use of lead-free crystal glass as glass and kitchen utensils, which is more safe and reliable. For health reasons, I hope you do not use glassware long bloom acidic beverages.
