調查檢測出多種有害金屬
消費者擔憂:化工原料添加有害
面對市場上大量添加化工原料的偽紫砂壺,很多消費者質疑,這些添加了色素及化工原料的紫砂壺,會不會含有害物質?消費者在使用它來泡水、泡茶時,會不會令有害物質釋出,從而被人體攝入?
廣州芳村紫砂產品經銷商許先生認為,目前市場上大量存在的所謂紫砂產品,存在安全隱患,“因為不知道添加的色素及其它化工合成品有沒有檢測,不知是否有害”。“為了安全,現在我們公司是自己採購原料,然後委托合作多年的大作坊代工生產。”該人士擔心地說。
據央視報道,記者在市場上隨機購買了15件紫砂壺和紫砂杯,送到上海材料研究所檢測中心進行檢測。檢測結果顯示,13件樣品重金屬溶出量都出現了異常。其中黑色壺的錳離子溶出量達到2.62mg/L,藍色壺的鋇離子溶出量高達6.39mg/L。
上海材料研究所檢測中心化學室主任馬衝先表示,重金屬熔點較高,在紫砂陶器的煅燒過程中很難揮發,最終還是會殘留在燒制好的茶具裏面,在使用時可能會產生不同程度的溶出量。專家認為,長期攝入鋇、錳、鈷、鉻等金屬離子,就會危及人體健康。
中國保健專家委員會副主任委員西木也指出,這些金屬如果是人工合成、並大量存在的形態,的確是有毒的。這些重金屬,有些是有害金屬,它會破壞人體的酶係統,破壞酶係統它就會產生很多毒性,包括神經毒性,如果是長期慢性的話也有致癌的作用。
CCTV H Yixing shady: dyed "purple sand" poison the market
The survey detected a variety of harmful metal
Consumer concern: chemical raw materials to add harmful
Pseudo teapot add a lot of chemical raw materials on the face of the market, many consumers questioned, these added Teapot of pigment and chemical raw materials, will not contain harmful substances? Consumers use it to flood damage, tea, will not lead to the release of hazardous substances, thereby thehuman intake?
Guangzhou the Fangcun Yixing products distributor Xu believes that currentlythere are a lot of the so-called purple clay products on the market, there are security risks, "added pigment and other chemical synthetics have not detected, I do not know whether it is hazardous because they do not know. "For safety, our company is sourcing raw materials, and then commissioned a large workshopOEM for many years." The person said to worry about.
According to CCTV reporter in the market randomly purchased 15 teapot andpurple cup, sent to the Shanghai Research Institute of Materials for testing. Thetest results showed that 13 samples leaching of heavy metals are the exception.Black pot of manganese dissolution reached 2.62mg / L, blue pot barium ionleaching of up to 6.39mg / L
Shanghai Research Institute of Materials Chemistry, director of horse red, saidhigh melting point of heavy metals in the calcination process of Yixing pottery is difficult to volatile eventually be left in the firing good tea inside, when in use may produce varying degrees of dissolution. The experts believe that long-term intake of barium, manganese, cobalt, chromium and other metal ions, it will endangerhuman health.
Nishiki of the vice chairman of China Health Care Committee of Experts also pointed out that, if the metal is a synthetic form, and there are a lot of really toxic.These heavy metals, some are harmful metals, it would disrupt the body's enzyme system, destruction of the enzyme system it will generate a lot of toxicity, includingneurotoxicity, if it is carcinogenic role of chronic words.
