英文摘要使用高效液相色谱-电感耦合等离子体质谱(HPlC-ICP-MS)联用技术对浒苔中的砷总量及其存在的化学形态进行分析。总量分析结果表明,青岛海域的浒苔样品中砷总量介于3.0~9.7μg/g之间。在总量测定的基础上,对浒苔样品的水煮提取液进行形态分析。结果表明,浒苔中主要含有无机五价砷和一种疑为砷糖的物质以及少量的二甲基胂酸(dMA)和无机三价砷。鉴于这些砷形态的毒性或潜在毒性,将其应用于食品及药物方面尚需谨慎。; This study analyzed arsenic content and speciation in Enteromorpha sampled from various coastal zones of Qindao using high performance liquid chromatography coupled to inductively coupled plasma-mass spectrometry(HPLC-ICP-MS).The results showed that the total arsenic content in Enteromorpha was ranged from 3.0 to 9.7 μg/g.The speciation analysis of hot water extract of Enteromorpha indicated that the major arsenic forms in Enteromorpha were inorganic quinquevalence arsenate and a substance suspected as arsenic sugar.Besides,there were small amounts of inorganic trivalence arsenite and dimethylarsenate(DMA) in the extract.Due to the toxicity or potential toxicity of these arsenic forms,it should be paid great caution in the application of Enteromorpha as a material for food and medicine.; 国家自然科学基金项目(20675021);海洋一所基本科研专项(GY-022008T32)
