水晶制品是一种颇具威胁的铅污染源,水晶制品中的氧化铅含量高达20％～30％,用它来盛水,一般还不至于引起铅中毒;但若用来盛酒酒会将水晶制品中的铅溶解出来并溶于酒。酒对铅元素的溶解量与时间呈正比,实验表明:用水晶容器盛酒,1小时后,酒中的含铅量升高1倍。由于水晶制品做工精细,外表晶莹剔透,故有“美丽的毒品”之称。 许多塑料餐具的表层图案中的铅、镉等金属元素会对人体造成伤害。一般的塑料制品表面有一层保护膜,这层膜一旦被硬器划破,有害物质就会释放出来。
Crystal products is a rather threatening source of lead pollution, crystal products, lead oxide content of up to 20% to 30%, to use it to hold water, generally not yet lead to lead poisoning; but if used to hold wine reception crystal products Lead dissolves and dissolves in wine. The amount of lead dissolved in the wine is proportional to the time. Experiments show that after 1 hour, the content of lead in the wine is doubled with the crystal container. As crystal products work fine, looks crystal clear, so there is a “beautiful drug” said. Many plastic tableware in the surface pattern of lead, cadmium and other metal elements will cause harm to the human body. General plastic products have a protective film on the surface, this layer of film once cut by the hard, harmful substances will be released.
