　　自3月16日(ri)始，全國多(duo)地發生食鹽(yan)搶購現(xian)象(xiang)。搶購主要(yao)由(you)于網絡(luo)傳言，網絡(luo)盛(sheng)傳海水受到污(wu)染，今后生產(chan)的(de)海鹽(yan)不安全、不能食用；含碘物品可以預(yu)防(fang)核輻射，還有人傳言鹽(yan)要(yao)漲價，造成部(bu)分民眾盲目(mu)搶購囤(dun)積碘鹽(yan)。浙江(jiang)、廣(guang)東、江(jiang)蘇、上海、四川、湖北、云(yun)南(nan)、貴州(zhou)、安徽、河南(nan)、湖南(nan)、北京等省市部(bu)分地區都出現(xian)搶購現(xian)象(xiang)。這(zhe)種現(xian)象(xiang)是一種非理性現(xian)象(xiang)，中(zhong)國鹽(yan)業總公司為此進(jin)行辟謠澄清，做出三(san)點說明：

　　1．中國完(wan)全(quan)有(you)能(neng)(neng)力(li)保(bao)障食鹽(yan)供(gong)應。各地食鹽(yan)供(gong)應出(chu)現緊(jin)張(zhang)，是(shi)由于短時(shi)間內(nei)大量(liang)搶(qiang)購所致(zhi)。事實上，中國的食鹽(yan)儲備非常(chang)充足，鹽(yan)業(ye)公(gong)司(si)一般都會有(you)三個月(yue)的庫(ku)存量(liang)，中國鹽(yan)的產(chan)能(neng)(neng)達到(dao)8000多萬噸，食鹽(yan)一年銷量(liang)只有(you)800多萬噸，生產(chan)銷售的食鹽(yan)絕(jue)大部(bu)分(fen)是(shi)井(jing)礦鹽(yan)。不(bu)管從產(chan)能(neng)(neng)還(huan)是(shi)產(chan)量(liang)來(lai)說，中國都完(wan)全(quan)有(you)能(neng)(neng)力(li)保(bao)障食鹽(yan)供(gong)應。目前，發生搶(qiang)購的地區鹽(yan)業(ye)公(gong)司(si)都已經啟動應急預案，實行24小(xiao)時(shi)緊(jin)急配送(song)，希望(wang)消費(fei)者不(bu)要信謠傳謠，不(bu)要盲目囤(dun)鹽(yan)搶(qiang)鹽(yan)。

　　2．食鹽(yan)價(jia)格是由國(guo)(guo)家定價(jia)，任何企業和個人都無權自行漲價(jia)。囤積居奇、哄抬鹽(yan)價(jia)的(de)行為，將受(shou)到國(guo)(guo)家有關部門的(de)處罰。3月17日，國(guo)(guo)家發展(zhan)改革委已發出緊急通知要求各地(di)立即開展(zhan)市場(chang)檢查，堅決打擊造(zao)謠惑眾(zhong)哄抬食用鹽(yan)價(jia)格等行為。

　　3．碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)防(fang)核(he)輻射、海(hai)水(shui)被污染沒(mei)有科學依據，請大家(jia)不要信(xin)謠傳(chuan)謠。在衛生部網站公(gong)布的(de)《放(fang)射防(fang)護中(zhong)的(de)碘(dian)(dian)(dian)(dian)(dian)知(zhi)識問答(da)》中(zhong)明確(que)指出：碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)中(zhong)碘(dian)(dian)(dian)(dian)(dian)的(de)存在形(xing)式(shi)是(shi)(shi)碘(dian)(dian)(dian)(dian)(dian)酸鉀（KIO3），在人(ren)體(ti)胃腸(chang)道和血液(ye)中(zhong)轉換成碘(dian)(dian)(dian)(dian)(dian)離子被甲(jia)狀腺(xian)吸收利用(yong)(yong)，我(wo)國規定碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)的(de)碘(dian)(dian)(dian)(dian)(dian)含量為30毫克(ke)(ke)(ke)/千克(ke)(ke)(ke)。按(an)人(ren)均每(mei)天食(shi)(shi)用(yong)(yong)10克(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)計算，可獲得0.3毫克(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)。而碘(dian)(dian)(dian)(dian)(dian)片碘(dian)(dian)(dian)(dian)(dian)的(de)存在形(xing)式(shi)是(shi)(shi)碘(dian)(dian)(dian)(dian)(dian)化鉀（KI），碘(dian)(dian)(dian)(dian)(dian)含量為每(mei)片100毫克(ke)(ke)(ke)。按(an)照每(mei)千克(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)含30毫克(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)計算，成人(ren)需要一次(ci)攝(she)入碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)約3千克(ke)(ke)(ke)，才(cai)能達(da)到預防(fang)的(de)效果，遠遠超出人(ren)類能夠承受的(de)鹽(yan)(yan)的(de)攝(she)入極限。因(yin)此(ci)，通過食(shi)(shi)用(yong)(yong)碘(dian)(dian)(dian)(dian)(dian)鹽(yan)(yan)預防(fang)放(fang)射性(xing)碘(dian)(dian)(dian)(dian)(dian)的(de)攝(she)入是(shi)(shi)無法實現的(de)。
