氢化物发生原子荧光法对贝类中无机砷监测及其安全性评价

摘要

通过氢化物发生原子荧光法检测浙江省舟山市主要菜场常见的4种贝类中无机砷的含量，并对其安全性进行评价。结果表明：4种贝类中可食部分的无机砷含量分别为花蛤0．138-0．191mg／kg、蜢蛏0．112-0．171mg／kg、牡蛎0．067-0．163mg／kg、贻贝0．070-0．168mg／kg，无机砷含量皆符合国家食品卫生标准。食用量低于世界卫生，粮农组织食品添加剂联合专家委员会推荐的129μg的限量。%This paper describes the application of hydride generation-atomic fluorescence spectrometry （CF-HGAFS） for the determination of inorganic arsenic in four main commercial shellfish species in Zhoushan city, Zhejiang province. Besides, their food safety was assessed. Inorganic arsenic contents in the edible parts of clam, razor clam, oyster and mussel found to be in the range of 138 -- 0.191, 0.112 - 0.171, 0.067 - 0.163, 0.070 - 0.168 mg/kg respectively, were consistent with the national food hygiene standards and inorganic arsenic intakes from them were below the WHO/FAO JECFA recommended acceptable daily intake （ADI） of 129μag per person per day.
