简述国内外目前非水产类食物中甲基汞的含量及其测量方法。报道表明,稻米类食物中甲基汞含量相对于其他非水产类食物中的含量要高,环境因素、基因属性可能是甲基汞向稻米转移的主要影响因素;目前非水产类食物中甲基汞含量测量主要采用色谱光谱或色谱质谱联用技术。但降低仪器使用成本、降低样品处理过程中的复杂性及试剂毒性,提高灵敏度仍是开发新型甲基汞检测技术的关键,随着传感类检测技术的发展,其有望在甲基汞检测方法方面得到广泛应用。
The contents and measurement methods of methylmercury in non-aquatic foods at home and abroad are briefly described. Reports indicate that the content of methylmercury in rice is higher than that of other non-aquatic foods, and the environmental and genetic attributes may be the main factors affecting the transfer of methylmercury to rice. At present, the content of methyl Mercury content measurement mainly used chromatographic or chromatographic mass spectrometry. However, it is still the key to develop the new methylmercury detection technology to reduce the instrument cost, reduce the complexity of sample processing and reagent toxicity, and increase the sensitivity. With the development of sensing type detection technology, it is expected that in the methylmercury detection method Has been widely used.
