摘要:

采用电感耦合等离子体质谱法(ICP-MS)和氢化物原子荧光光度法(HG-AFS)分析了进口北极甜虾(Pandalusborealis)不同组织部位的重金属(铅、总汞、镉、硒、总砷、无机砷)含量情况。结果表明:北极甜虾样品中铅、总汞、镉、硒、总砷、无机砷均有一定程度的检出;不同组织部位的重金属含量存在差异,头部是重金属富集的主要部位;按照NY5073 — 2001 的取制样方法进行检验,北极甜虾样品中的重金属含量均低于国家限定标准;建议实验室取样制样时统一采用NY5073 — 2001 的规定进行,即将虾洗净,去头、去皮、去肠腺(大型虾)后取肌肉。

Abstract:

The contents of heavy metals such as Pb, total Hg, Cd, Se and total As in different parts of Pandalus borealis were analyzed by ICP-MS method and inorganic As by HG-AFS method. The results showed that Pb, total Hg, Cd, Se, total As and inorganic As all were detected in Pandalus borealis. The levels of heavy metals varied in the different parts of Pandalus borealis and high concentration of metals were found in head. Shrimp were sampled and analyzed based on NY5073-2001 (an agricultural standard issued by the Chinese ministry of agriculture). The contents of heavy metals were showed below the level of national sanitation limits. A standard procedure for measuring heavy metals in shrimps is proposed by cleaning, removing the head, shell and enteraden (if it is a large-sized shrimp) and keeping the muscle for analysis.

Key words: Pandalus borealis, heavy metal, content, distribution, sampling
