　　自3月16日始，全(quan)國(guo)多地發(fa)生食(shi)鹽搶購(gou)現(xian)象。搶購(gou)主要(yao)由于網絡傳(chuan)言，網絡盛傳(chuan)海水受到污染，今后生產的海鹽不安全(quan)、不能(neng)食(shi)用；含碘物品可以預防核輻射，還有人傳(chuan)言鹽要(yao)漲價，造成(cheng)部分(fen)民眾(zhong)盲目搶購(gou)囤積碘鹽。浙江、廣東、江蘇、上(shang)海、四(si)川、湖(hu)北、云南、貴州、安徽、河南、湖(hu)南、北京等省市(shi)部分(fen)地區都(dou)出(chu)現(xian)搶購(gou)現(xian)象。這種現(xian)象是一種非(fei)理(li)性現(xian)象，中國(guo)鹽業總公司為此進行辟謠澄清(qing)，做出(chu)三(san)點說明：

　　1．中國(guo)完全(quan)有(you)能(neng)(neng)力保障食鹽供應。各地食鹽供應出現(xian)緊(jin)張，是(shi)由于短時(shi)間(jian)內大(da)(da)量搶(qiang)購所(suo)致。事實(shi)(shi)上，中國(guo)的食鹽儲備非常充足，鹽業(ye)公司(si)一般都(dou)會有(you)三個月的庫存量，中國(guo)鹽的產能(neng)(neng)達到8000多(duo)萬噸，食鹽一年銷(xiao)量只有(you)800多(duo)萬噸，生(sheng)產銷(xiao)售的食鹽絕(jue)大(da)(da)部分是(shi)井礦鹽。不管(guan)從產能(neng)(neng)還是(shi)產量來說(shuo)，中國(guo)都(dou)完全(quan)有(you)能(neng)(neng)力保障食鹽供應。目(mu)(mu)前，發(fa)生(sheng)搶(qiang)購的地區鹽業(ye)公司(si)都(dou)已經啟動應急預(yu)案，實(shi)(shi)行(xing)24小(xiao)時(shi)緊(jin)急配送，希望消費(fei)者(zhe)不要信謠傳謠，不要盲目(mu)(mu)囤鹽搶(qiang)鹽。

　　2．食鹽(yan)價(jia)(jia)格是由國(guo)(guo)家定價(jia)(jia)，任何(he)企業(ye)和個人都無權自行(xing)漲價(jia)(jia)。囤積(ji)居奇、哄抬(tai)鹽(yan)價(jia)(jia)的(de)行(xing)為(wei)(wei)，將受到國(guo)(guo)家有關部門的(de)處(chu)罰(fa)。3月17日，國(guo)(guo)家發(fa)展改革(ge)委已(yi)發(fa)出緊急(ji)通(tong)知(zhi)要求各地立即(ji)開展市場檢(jian)查，堅決打擊(ji)造謠(yao)惑眾(zhong)哄抬(tai)食用(yong)鹽(yan)價(jia)(jia)格等(deng)行(xing)為(wei)(wei)。

　　3．碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)防(fang)核輻射(she)、海水被污染沒有科學依據，請大家不要信謠傳謠。在(zai)衛生部網站公布的(de)《放射(she)防(fang)護中(zhong)(zhong)的(de)碘(dian)(dian)(dian)(dian)知識(shi)問答》中(zhong)(zhong)明確指(zhi)出(chu)(chu)：碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)中(zhong)(zhong)碘(dian)(dian)(dian)(dian)的(de)存(cun)在(zai)形(xing)式是碘(dian)(dian)(dian)(dian)酸鉀(jia)（KIO3），在(zai)人(ren)體胃(wei)腸道和血液中(zhong)(zhong)轉(zhuan)換成碘(dian)(dian)(dian)(dian)離(li)子被甲狀腺(xian)吸收(shou)利用(yong)(yong)，我國(guo)規定碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)的(de)碘(dian)(dian)(dian)(dian)含量(liang)為(wei)30毫(hao)(hao)(hao)克(ke)(ke)(ke)(ke)/千克(ke)(ke)(ke)(ke)。按人(ren)均每(mei)天食用(yong)(yong)10克(ke)(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)計(ji)算，可獲得0.3毫(hao)(hao)(hao)克(ke)(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)。而碘(dian)(dian)(dian)(dian)片碘(dian)(dian)(dian)(dian)的(de)存(cun)在(zai)形(xing)式是碘(dian)(dian)(dian)(dian)化鉀(jia)（KI），碘(dian)(dian)(dian)(dian)含量(liang)為(wei)每(mei)片100毫(hao)(hao)(hao)克(ke)(ke)(ke)(ke)。按照每(mei)千克(ke)(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)含30毫(hao)(hao)(hao)克(ke)(ke)(ke)(ke)碘(dian)(dian)(dian)(dian)計(ji)算，成人(ren)需要一次攝入(ru)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)約3千克(ke)(ke)(ke)(ke)，才能(neng)達到預(yu)防(fang)的(de)效果，遠遠超(chao)出(chu)(chu)人(ren)類能(neng)夠承受(shou)的(de)鹽(yan)(yan)(yan)(yan)(yan)的(de)攝入(ru)極限。因此，通過食用(yong)(yong)碘(dian)(dian)(dian)(dian)鹽(yan)(yan)(yan)(yan)(yan)預(yu)防(fang)放射(she)性(xing)碘(dian)(dian)(dian)(dian)的(de)攝入(ru)是無法實現的(de)。
