海产品中砷形态分析研究进展
我国是海产品的生产和消费大国, 所以海产品的安全问题受到人们越来越多的关注。海产品特别是食用海藻含砷量较高, 但是海产品中的砷大部分以低毒性的有机砷形态存在, 而且不同种类的海产品所含有的砷形态各不相同。所以, 对海产品中的不同形态砷化合物进行精准分析检测, 对于科学、客观评估海产品中砷污染的健康风险以及保证海产品的安全消费具有重要意义。海产品的砷形态分析面临的困难主要是, 第一在不改变砷形态的前提下把海产品中所有形态砷化合物完全提取出来; 第二把各形态有机砷和无机砷在较短时间内实现基线分离、并对各形态砷化合物进行高灵敏检测。近十多年来, 有关海产品中砷的形态分析得到越来越多的关注, 在方法学上也取得了显著的进步。本文主要针对近十多年来有关不同海产品中不同形态砷化合物的提取方法和分析检测方法方面的研究进展进行了概述, 以期为食品检测机构或食品安全研究或评估人员提供方法学上的参考。
China is a big country in the production and consumption of seafood in the world, thus, the safety of seafood has attracted increasing attention. In general, seafood especially edible seaweeds contain higher level of arsenic. However, most of the arsenic species in seafood is low toxic organic arsenic, and the arsenic species in different kinds of marine products are different. Therefore, accurate analysis of different arsenic species in seafood is of great significance for the scientific and objective assessment of the health risks of arsenic pollution in seafood and for ensuring the safe consumption of seafood. The main difficulties for arsenic speciation analysis in seafood are as follow: Firstly, all arsenic species in seafood must be completely extracted without changing their speciation; Secondly, all arsenic species including organic arsenic and inorganic arsenic must be baseline separated in a short time and are detected with high sensitivity. In the past decade, more and more attention has been paid to the speciation analysis of arsenic in seafood, and notable progress has been made in methodology. This paper summarized the research progress on the extraction and analysis of different arsenic species in different seafood in recent ten years, in order to provide methodological reference for food testing institutions or food safety researchers or evaluators.
