民以食為天，食以安為先，食品參與構(gòu)成了人類社會生存發(fā)展的基礎(chǔ)，是維持生命活動的必需消耗品。近年來，隨著我國社會經(jīng)濟的迅速發(fā)展，食品產(chǎn)業(yè)“泡沫化”現(xiàn)象逐步抬頭。自然環(huán)境不斷遭到破壞導(dǎo)致水污染、空氣污染、土壤污染日益嚴重，進而引起食品安全問題頻發(fā)，“砷毒”、“鎘米”等重金屬污染事件成為受關(guān)注的公共衛(wèi)生事件。 </p> <p> 在滿足公眾食品消費需求的同時，其安全衛(wèi)生問題已成為嚴峻的社會問題，得到各國監(jiān)管者的高度重視。食品重金屬污染由于其毒性強、可蓄積、半衰期長等特性，不*成為**開發(fā)計劃署（UNDP）、**糧食及農(nóng)業(yè)組織（FAO）、世界衛(wèi)生組織（WHO）的全球食物污染物監(jiān)測計劃中的重要項目，也是我國目前食品污染領(lǐng)域重點監(jiān)測項目之一。
