【摘要】 本文以水产品中砷污染现状、生物体内富集转化规律研究近况及常见砷形态分析方法发展为主线,讨论砷形态分析在砷污染问题上的迫切性,总结砷在原核生物、真核生物、哺乳动物和高等植物中的富集及解毒机制的研究进展,简述了不同砷形态分析方法的发展、应用及其优缺点。砷的存在形态决定了水产品中砷污染的毒性,单用砷的总含量评价砷对环境和生物的污染不能真实反映砷污染,应评估其具体的形态和毒性效果。早期主要用色谱和原子光谱联用分析砷,随着检测技术的更新,目前食品安全国家标准中已采用高效液相色谱串联原子荧光光谱法和高效液相色谱串联电感耦合等离子体质谱法测定总砷及无机砷的含量。结合国际上最新的研究进展,讨论砷形态分析方法在环境毒理学等研究中的重要作用。更多还原

【Abstract】 This paper focuses on present status of arsenic pollution in fishery products, accumulation and transformation in organisms and development of common arsenic speciation analysis methods. The urgency of arsenic speciation analysis on arsenic pollution is described, and the accumulation of arsenic in prokaryotes, eukaryotes, mammals and higher plants and the corresponding detoxification mechanism are summarized. The development process and application of different arsenic analysis methods and the advantages and disadvantages of different methods were briefly reviewed. Arsenic pollution in fishery products is more common. With the existence of arsenic, the biological and chemical toxicity of arsenic pollution in fishery products is discussed, and it is not reflect the status of arsenic pollution in the environment and organisms based on the evaluation of pollution of arsenic only by the total content of arsenic. It is necessary for analysis and evaluation of the arsenic form. The early analysis of arsenic speciation is the combination of chromatography and atomic spectroscopy as the main means. As the detection technology is updated, the arsenic speciation of total arsenic and inorganic arsenic in national standard for food safety has been detected by high performance liquid chromatography tandem atomic fluorescence spectrometry and high performance liquid chromatography tandem inductively coupled plasma mass spectrometry. Combined with the latest research progress in the world, the important role of arsenic speciation analysis method in environmental toxicology is discussed.更多还原
