This study analyzed total mercury (THg), and selenium (Se) in edible tissues of white shrimp (Litopenaeus vannamei), blue shrimp (L. stylirostris) and brown shrimp (F. californiensis), from three states of the Northwest of Mexico in September and October 2017. Concentrations of THg and Se in the muscle were between 0.026 and 0.829 and 0.126-1.741 µg/g dry weight (dw), respectively. Significant differences were observed among Hg concentration of Sonora and Nayarit and among Se concentration of Sinaloa and Nayarit. In addition, the health risk assessment (HQ) in the three species of shrimp was between 0.550 and 0.607. All Se:Hg molar ratios were > 1 and positive HBV values that showed that shrimp from Northwest of Mexico does not represent a risk to human health.
本研究分析了2017年9月和10月从墨西哥西北部三个州采集的白虾（凡纳滨对虾）、蓝虾（斯氏对虾）和棕虾（加利福尼亚褐虾）可食用组织中的总汞（THg）和硒（Se）。肌肉中THg和Se的浓度分别在0.026至0.829和0.126 - 1.741微克/克干重（dw）之间。索诺拉州和纳亚里特州的汞浓度之间以及锡那罗亚州和纳亚里特州的硒浓度之间存在显著差异。此外，三种虾的健康风险评估（HQ）在0.550至0.607之间。所有硒与汞的摩尔比均>1且乙肝病毒值为正，这表明墨西哥西北部的虾对人类健康不构成风险。
