Drinking alcoholic beverages in a crystal glass will cause chronic poisoning, you must know this
It is common to serve red wine and champagne by the glass. Looking at the brilliance of the reflection of the glass and the clear color of the wine, one cannot put it down. As we all know, if the “crystal cup” made of leaded glass is used to hold acidic beverages such as lemon juice and honey, or wine is improperly stored, it will lead to lead pollution and seriously endanger human health.
Food and drinks served in crystal tableware look gorgeous and addictive. But many people can’t imagine that it can also cause chronic poisoning.
Experts say crystal products are a threatening source of lead pollution. The lead oxide content is often as high as 20% – 30%. Using it to hold water will generally not cause lead poisoning. However, if it is used to hold wine or acidic beverages, the lead in crystal products will be precipitated and dissolved in wine. or acidic beverages. Experiments have shown that the longer the wine is served, the higher the lead content in the wine. Another foreign experiment has proved that if 1 liter of brandy wine is placed in a crystal vessel, after 5 years, the lead content in the wine can be as high as 20,000 micrograms / liter, far exceeding the environmental protection department’s statement that the lead content in drinks should be lower than 50 µg/L regulation.
The World Health Organization defines lead poisoning if a person’s blood lead level is greater than 100 micrograms per liter. When the lead in the blood accumulates to a certain extent, it will make people’s memory and intelligence decline, and there will be mental disorders, nightmares, insomnia and other problems. Lead poisoning is more harmful to children, and it is easy to cause mental retardation in children. Therefore, it is necessary to avoid long-term storage of alcohol, fruit juice or acidic beverages with crystal products, so as to avoid poisoning caused by lead accumulation and damage to health.
When buying crystal glass tableware, you can distinguish crystal glass from ordinary glass by appearance, feel and sound. The refractive index of ordinary glass products is lower than that of crystalline products. It doesn’t look as bright as crystal glass. Some even have foam. A light tap produces a dull “pop” sound. Compared with ordinary glass products, crystal glass products have bright colors and strong refractive index. They look like they are made of crystal. This makes the sound of hitting metal a little harsh.
