重金屬在環(huán)境中的滲透性強(qiáng)，并可通過食物鏈富集作用不斷蓄積，自發(fā)降解緩慢，且不易被無害化處理，對受污染食品具有深遠(yuǎn)持久的影響。由此可見，基于工業(yè)生產(chǎn)活動(dòng)排放的重金屬對食品的污染較為嚴(yán)重。 </p> <p> 研究發(fā)現(xiàn)，葉菜類蔬菜比非葉菜類蔬菜更易污染，其中白菜的污染**嚴(yán)重，鎘濃度可超過較大允許含量的4.5倍。利用被重金屬污染的水源灌溉農(nóng)作物如水稻，會(huì)導(dǎo)致重金屬在農(nóng)產(chǎn)品中大量蓄積，增加對人類的健康風(fēng)險(xiǎn)。中東地區(qū)礦區(qū)蚯蚓組織中的鎘含量比在土壤高8~10 倍，而鼴鼠肝臟又比蚯蚓的組織高4~6 倍，表明重金屬在食物鏈中蓄積性強(qiáng)，嚴(yán)重危害食品的安全性。 </p> <p> 此外，農(nóng)作物中重金屬的殘留水平與工廠距離呈負(fù)相關(guān)。牧草中重金屬含量與污染源之間的距離呈負(fù)相關(guān)，且其鉛、鎘、鋅含量的相關(guān)系數(shù)（r）分別為0.97、0.99

礦山開發(fā)、金屬冶煉、工礦企業(yè)生產(chǎn)等活動(dòng)產(chǎn)生大量重金屬廢料，以及工業(yè)“三廢”的不合理排放，使得重金屬進(jìn)入生態(tài)環(huán)境導(dǎo)致空氣、土壤及水體受到污染，是造成食品重金屬污染的主要途徑。 </p> <p> 據(jù)統(tǒng)計(jì)，全世界每年消耗的鉛約有400萬噸，鎘消耗量約為2萬噸，汞消耗量約為1萬噸，砷消耗量約為2. 4萬噸，這些重金屬只有少量被回收利用，其余大部分以各種形式被排放到環(huán)境中造成污染。我國因工業(yè)“三廢”和污水灌溉已造成有70%的水域面積存在不同程度的污染，汞、鎘、鉻、鉛、砷等重金屬污染的耕地面積約已占我國耕地總面積的1/5，全國每年因重金屬污染而減產(chǎn)糧食1000多萬噸。 </p> <p> <br />

style="text-indent:25px">某些地區(qū)特殊的自然地質(zhì)條件會(huì)造成食品原材料在生長過程中受到重金屬污染。尤其是礦區(qū)、海底火山活動(dòng)區(qū)域，其重金屬自然本底值明顯高于其他區(qū)域，并隨自然沉降作用向周邊土壤、空氣和水體等介質(zhì)發(fā)散，隨后波及到食品原材料，使得當(dāng)?shù)厥称分亟饘傥廴舅竭h(yuǎn)超出國家標(biāo)準(zhǔn)。如我國甘肅白銀礦區(qū)牧草鉛、鎘的平均含量可達(dá)正常區(qū)域的9倍和680倍，糧食為對照組的10倍和35倍，達(dá)到極明顯水平（P＜0.01）；開封礦區(qū)附近的小麥和玉米中鎘、鉛、汞的超標(biāo)率分別為9.46%、1.84%、3.57%

盡管靶向改性材料是有機(jī)官能樹脂的一大進(jìn)步，但是面對現(xiàn)有技術(shù)和新技術(shù)的挑戰(zhàn)（如低雜質(zhì)含量、選擇性和高吸附量），靶向改性材料技術(shù)仍需明顯提升。 </p> <p> 在原材料產(chǎn)品中的金屬殘留物或污水中的金屬催化劑的化學(xué)形態(tài)會(huì)與起初的金屬形態(tài)截然不同，在復(fù)雜的工藝之后，同樣的金屬往往會(huì)有多種不同的形態(tài)共存，如不同的氧化態(tài)、單分子到納米顆粒、緊密結(jié)合有不同的復(fù)合物或配位體的多金屬物種。金屬不同形態(tài)的分布會(huì)根據(jù)不同***生產(chǎn)工藝的變化而改變，因此為了保證產(chǎn)品的品質(zhì)和金屬的回收，新型官能化材料必須含有復(fù)雜的官能團(tuán)組合，并能對多種不同金屬形態(tài)提供相應(yīng)的固定機(jī)理以保證吸附效果。同時(shí)，官能團(tuán)也必須附載于骨架上的孔隙表層，配合特定的空間分布才能確保溶液當(dāng)中配合基的置換與捕捉。不同的金屬極有可能需要不同的捕捉機(jī)理，為保證捕捉效果官能材料的設(shè)計(jì)必須考慮各種多種機(jī)理的組合。官能材料的穩(wěn)定性（溫度、物理、化學(xué)）、官能團(tuán)的附載率和有效性、有機(jī)溶液的兼容性、親水性和材料的不膨脹性都是設(shè)計(jì)中必須要考量的因素。功能材料的生產(chǎn)成本也是一項(xiàng)重要因素，靶向改性材料的設(shè)計(jì)需要一個(gè)特定的化學(xué)反應(yīng)和簡易的生產(chǎn)工藝將多種高度復(fù)雜的官能團(tuán)共價(jià)于改性材料表面。東莞除砷絮凝劑價(jià)格</p><p>
