Abstract

The concentration of methylmercury (MMC) and total mercury (TMC) in marine fishes (five species) frequently consumed in the coastal areas of Zhejiang province, China, was determined. The method of high-performance liquid chromatography-atomic fluorescence spectrometry (HPLC-AFS) with the microwave-assisted extraction was used for the MMC determination. TMC was analysed by a direct mercury analyser. MMC and TMC concentrations in five fish species ranged from 53 to 158 µg kg⁻¹ and 60 to 172 µg kg⁻¹, respectively. The proportion of MMC levels in TMC was greater than 80%. The highest MMC and TMC levels were found in Hairtail.

摘要

测定了中国浙江省沿海地区常食用的五种海洋鱼类（五种）中甲基汞（MMC）和总汞（TMC）的浓度。采用微波辅助萃取高效液相色谱-原子荧光光谱法（HPLC-AFS）测定 MMC。用直接测汞仪分析 TMC。五种鱼中 MMC 和 TMC 的浓度范围分别为 53 至 158μg/kg 和 60 至 172μg/kg。MMC 水平在 TMC 中的比例大于 80%。在带鱼中发现了最高的 MMC 和 TMC 水平。
