食品中鎘元素檢測(cè)方法的研究進(jìn)展
摘 要:重金屬鎘作為人體非必需元素,具有一定的生物學(xué)毒性,生物半衰期達(dá)10~30年,在人體內(nèi)不斷累積會(huì)對(duì)各器官造成影響并引發(fā)各種疾病。在鎘暴露中,飲食是人體攝入鎘的重要途徑。相比其他重金屬,鎘更易被農(nóng)作物吸收?;诖耍疚木C述了鎘金屬元素的常規(guī)檢測(cè)方法,為食品中鎘的檢測(cè)提供參考。

Abstract: Cadmium, as a non essential element in the human body, has a certain biological toxicity with a biological half-life of 10 to 30 years. Its continuous accumulation in the human body can affect various organs and cause various diseases. In cadmium exposure, diet is an important pathway for the human body to ingest cadmium. Compared to other heavy metals, cadmium is more easily absorbed by crops. Based on this, this article reviews the conventional detection methods for cadmium metal elements, providing reference for the detection of cadmium in food.
Keywords: food; cadmium element; test method
目前,用于檢測(cè)食品中鎘含量的技術(shù)發(fā)展迅速,主要是基于實(shí)驗(yàn)室儀器設(shè)備等的精確檢測(cè)方法和現(xiàn)場(chǎng)快速檢測(cè)技術(shù),包括石墨爐原子吸收光譜法(Graphite Furnace Atomic Absorption Spectrometry,GFAAS)、火焰原子吸收光譜法(Flame Atomic Absorption Spectrometry,F(xiàn)AAS)、原子發(fā)射光譜法(Optical Emission Spectrometry,OES)、電感耦合等離子體質(zhì)譜法(Inductively Coupled Plasma Mass Spectrometry,ICP-MS)和激光誘導(dǎo)擊穿光譜法(Laser-Induced Breakdown Spectroscopy,LIBS)等儀器方法,以及酶聯(lián)免疫法、電化學(xué)分析法等快檢方法,對(duì)樣品進(jìn)行相應(yīng)的前處理后,能高效精準(zhǔn)地對(duì)Cd進(jìn)行定性篩查和定量檢測(cè)。(剩余5309字)
