The present study analyzed the content of total mercury (THg) and selenium (Se) in the muscle of shrimp collected from local markets in the 11 Pacific coastal states of Mexico. Methylmercury (MeHg) concentration, Se:Hg ratio, health benefits value from selenium consumption (HBV) and the permissible weekly consumption were estimated to assess the health risk to consumers. All THg and Se concentrations were below the maximum permissible limits. All hazard quotient (HQ) values were <1, however in Hermosillo, Culiacán and Guadalajara, the Se:Hg ratio and HBV were <1 and negative, due to the low concentrations of Se. As a general conclusion, there is no risk nor benefit from the consumption of shrimp from the Pacific coast of Mexico due to its Hg and Se content.
本研究分析了从墨西哥11个太平洋沿岸州当地市场采集的虾类肌肉中总汞（THg）和硒（Se）的含量。估算了甲基汞（MeHg）浓度、硒汞比、硒消费带来的健康益处值（HBV）以及每周允许摄入量，以评估对消费者的健康风险。所有总汞和硒浓度均低于最大允许限值。所有危害商数（HQ）值均<1，然而在埃莫西约、库利亚坎和瓜达拉哈拉，由于硒浓度较低，硒汞比和HBV<1且为负值。总体而言，由于汞和硒含量，食用墨西哥太平洋沿岸的虾类既无风险也无益处。
