自3月16日始，全(quan)國(guo)多地發生食鹽(yan)搶(qiang)(qiang)(qiang)購現象(xiang)。搶(qiang)(qiang)(qiang)購主(zhu)要(yao)由于網絡傳(chuan)(chuan)言，網絡盛傳(chuan)(chuan)海水受到污(wu)染，今后生產的海鹽(yan)不安(an)(an)全(quan)、不能食用(yong)；含碘物品可(ke)以(yi)預防核輻射，還有人傳(chuan)(chuan)言鹽(yan)要(yao)漲價，造成部分(fen)民眾盲(mang)目搶(qiang)(qiang)(qiang)購囤積(ji)碘鹽(yan)。浙(zhe)江、廣東(dong)、江蘇(su)、上海、四川、湖(hu)北(bei)、云南(nan)、貴州、安(an)(an)徽、河南(nan)、湖(hu)南(nan)、北(bei)京等(deng)省市部分(fen)地區都出(chu)(chu)現搶(qiang)(qiang)(qiang)購現象(xiang)。這種現象(xiang)是一種非理性現象(xiang)，中國(guo)鹽(yan)業(ye)總公(gong)司為此進行辟謠澄(cheng)清，做出(chu)(chu)三(san)點說(shuo)明：
1．中(zhong)國完(wan)全有能力(li)(li)保障食(shi)(shi)(shi)鹽(yan)供(gong)(gong)應(ying)(ying)。各地(di)食(shi)(shi)(shi)鹽(yan)供(gong)(gong)應(ying)(ying)出現緊張(zhang)，是由于短時(shi)間內(nei)大量(liang)搶購所致。事實上，中(zhong)國的(de)食(shi)(shi)(shi)鹽(yan)儲備非常(chang)充足，鹽(yan)業(ye)公司(si)一般(ban)都會有三個月(yue)的(de)庫存量(liang)，中(zhong)國鹽(yan)的(de)產能達到8000多萬(wan)噸，食(shi)(shi)(shi)鹽(yan)一年銷量(liang)只有800多萬(wan)噸，生產銷售的(de)食(shi)(shi)(shi)鹽(yan)絕大部分(fen)是井礦鹽(yan)。不管從產能還是產量(liang)來說，中(zhong)國都完(wan)全有能力(li)(li)保障食(shi)(shi)(shi)鹽(yan)供(gong)(gong)應(ying)(ying)。目前，發生搶購的(de)地(di)區鹽(yan)業(ye)公司(si)都已(yi)經啟動應(ying)(ying)急預(yu)案，實行(xing)24小時(shi)緊急配送，希望消費者不要信謠傳(chuan)謠，不要盲(mang)目囤鹽(yan)搶鹽(yan)。
2．食鹽(yan)價(jia)格(ge)是由(you)國(guo)(guo)家(jia)定價(jia)，任何企(qi)業(ye)和個人(ren)都無權(quan)自行漲價(jia)。囤積居(ju)奇、哄抬鹽(yan)價(jia)的行為，將受到國(guo)(guo)家(jia)有關部(bu)門的處罰。3月17日，國(guo)(guo)家(jia)發展(zhan)改革委已(yi)發出緊急通知(zhi)要(yao)求各地立即開展(zhan)市場檢查，堅決打(da)擊造謠惑眾哄抬食用鹽(yan)價(jia)格(ge)等行為。
3．碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)防(fang)核輻射、海水被污染沒有科學(xue)依(yi)據，請大家不要(yao)信謠傳謠。在衛生部網站公布(bu)的(de)(de)《放射防(fang)護中(zhong)的(de)(de)碘(dian)(dian)(dian)(dian)(dian)(dian)知識問答》中(zhong)明確指出：碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)中(zhong)碘(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)存在形式(shi)是(shi)碘(dian)(dian)(dian)(dian)(dian)(dian)酸(suan)鉀(jia)（KIO3），在人(ren)體胃腸道和血(xue)液(ye)中(zhong)轉換(huan)成碘(dian)(dian)(dian)(dian)(dian)(dian)離子被甲狀(zhuang)腺吸收利(li)用，我國規定碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)的(de)(de)碘(dian)(dian)(dian)(dian)(dian)(dian)含(han)(han)量為30毫(hao)(hao)(hao)克(ke)(ke)/千(qian)克(ke)(ke)。按人(ren)均每天食用10克(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)計算，可獲得0.3毫(hao)(hao)(hao)克(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)(dian)。而碘(dian)(dian)(dian)(dian)(dian)(dian)片(pian)碘(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)存在形式(shi)是(shi)碘(dian)(dian)(dian)(dian)(dian)(dian)化鉀(jia)（KI），碘(dian)(dian)(dian)(dian)(dian)(dian)含(han)(han)量為每片(pian)100毫(hao)(hao)(hao)克(ke)(ke)。按照每千(qian)克(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)含(han)(han)30毫(hao)(hao)(hao)克(ke)(ke)碘(dian)(dian)(dian)(dian)(dian)(dian)計算，成人(ren)需(xu)要(yao)一次攝(she)入(ru)碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)約3千(qian)克(ke)(ke)，才(cai)能達到預(yu)防(fang)的(de)(de)效果，遠(yuan)遠(yuan)超出人(ren)類(lei)能夠承受的(de)(de)鹽(yan)的(de)(de)攝(she)入(ru)極限。因此，通過食用碘(dian)(dian)(dian)(dian)(dian)(dian)鹽(yan)預(yu)防(fang)放射性碘(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)攝(she)入(ru)是(shi)無法實現的(de)(de)。
