食品中汞与甲基汞污染状况与检测技术研究进展

Research progress on pollution and detection technology of mercury and methylmercury in food

汞在环境中污染相当普遍且对人体健康危害极大,如可造成大脑损伤、肾脏衰竭、神经系统及免疫系统损伤等。一般人接触汞主要是通过食品,因此了解食品中汞污染状况具有重要意义。该文就食品中汞污染的来源、现状、危害及国内外汞限量标准进行概述,对食品样品中汞检测的前处理技术、检测技术进行了对比分析,展望了食品中元素汞检测技术的发展方向。

Mercury is a kind of heavy metal which is harmful to human and is widely polluted in the environment,the exposure to mercury can cause a series of harmful effects on health in varying degrees,such as brain damage,kidney failure,nervous system and immune system damage. People’s main contamination by mercury comes from foods,so it is important to determination mercury. This paper summarizes the present situation,source and harm of mercury pollution,introduces the limitation of mercury in food domestic and abroad,analyses the detection technology of mercury in food and prospects the development of detection technology.
