摘要/Abstract

摘要： 于1999—2004年对福建沿岸16个港湾的海水养殖贝类质量检测。结果表明：15种贝类152个样品中，总汞含量范围为0.002～0.035 mg·kg^-1，与近20多年来福建省相关的海洋生物质量调查结果比较，贝类体内总汞含量处于较稳定的水平；贝类体内总汞含量较低，符合国家水产品卫生和质量安全指标，也符合欧共体和世界卫生组织规定的鱼贝类汞限量标准；以每人100 g·d^-1的贝类摄食量估算，福建沿海城乡居民食用贝类的汞和甲基汞摄入量低于WHO推荐的PTWI值，也低于美国环境保护署设定的甲基汞参考剂量RfD值。因此，由贝类水产品消费引起的甲基汞暴露健康风险很小。

Abstract: The 1999-2004 quality monitoring data of seawater-cultured shellfish in 16 bays along Fujian coastal areas showed that in 152 samples of 15 kinds of shellfish, the total mercury content ranged from 0.002-0.035 mg·kg^-1. Comparing with the recent 20 years quality monitoring data of marine organisms in Fujian, the total mercury content in the shellfish was relatively low, being accorded with the China national standard of aquatic products for hygienic and safe evaluation, and the MRLS of mercury content in fish and shellfish ordered by the European Community and WHO. With the mercury intake from shellfish being 100 g per person per day as the base of estimation, the intake of mercury and methyl mercury from shellfish by the inhabitants along Fujian coastal areas was lower than the PTWI value recommended by WHO and the RfD value of methyl mercury regulated by US EPA, indicating that the health risk arising from the exposure to methyl mercury due to the consumption of aquatic products was very small.
