光谱分析技术在水产品重金属检测中的应用

Application of Spectroscopy Analysis Technology for Detecting the Heavy Metals in Aquatic Products

水产品对铅、镉、汞、砷等重金属元素具有较强的富集能力,并且会通过食物链的传递与生物富集化,重金属会通过食物链进入人类体内。由金属离子产生的氧化应激引起的紊乱和损伤已经被人们发现,对人类生命造成严重的威胁。因此,水产品中的重金属含量的检测对评价水产品食用安全性以及保护生命健康具有重要意义。光谱分析法是各类水产品重金属高效的检测方法之一。本文对水产品中重金属的检测方法中光谱分析法,特别是原子吸收光谱法、原子发射光谱法、原子荧光光谱法、紫外–可见吸收光谱法、红外光谱法等进行了概述,并提出今后的光谱技术发展方向,为我国水产品重金属检测提供技术保障。

Aquatic products have a strong ability to accumulate heavy metals such as lead, cadmium, mer-cury, arsenic and other heavy metals. They will pass through the food chain and be bio-enriched, and will be ingested into humans. Disorders and damages produced by oxidative stress caused by metal-ions have been discovered, posing a serious threat to human life. Therefore, the detection of heavy metal content in aquatic products is of great significance for evaluating the edible safety of aquatic products and protecting life and health. Among the various methods for detecting heavy metals in aquatic products, spectral analysis is one of the most efficient methods for heavy metal detection in aquatic products. This article summarizes the spectroscopic analysis methods in the detection methods of heavy metals in aquatic products, especially the atomic absorption spectrometry, atomic emission spectrometry, atomic fluorescence spectrometry, and ultraviolet-visible absorption spectroscopy, etc., and proposes the future development direction of spectroscopy technology. This can provide technical support for the detection of heavy metals in aquatic products of our country.
