With the aim of evaluating health risk to hake consumers, mercury and selenium were measured in muscle, liver, gonads, kidney, and gills of 62 specimens of Merluccius productus from northern Gulf of California. Means ± confidence interval (95% confidence level) concentrations (mg kg-1 wet weight) of Hg in tissues were: gonads (1.01 ± 0.25) > muscle (0.44 ± 0.06) > gills (0.29 ± 0.04) > kidneys (0.20 ± 0.07) > liver (0.02 ± 0.004). No significant differences between sexes were found for Hg. The distribution of mean concentrations of Se (mg kg-1 wet weight) were: kidneys (4.61 ± 1.27) > liver (1.66 ± 0.22) > gonads (1.66 ± 0.75) > gills (0.86 ± 0.04) > muscle (0.40 ± 0.09). Se in gonads showed a significant difference between sex (females > males). Positive significant correlations with total length (p < 0.05) and total weight (p < 0.05) were found in the same tissue for both morphological variables: Hg in muscle, Se in muscle and Se in liver. An excess of Se over Hg (molar ratio Se:Hg > 1) was found in all tissues. The Hazard Quotient health risk index was evaluated for humans that consume muscle and gonads. The recommended Hg safe intake for adults and children were 110.0 and 33.0 g week-1, respectively for muscle; for gonads weekly consumption portions of 35.0 and 14.0 g for adults and children represent no Hg risk. There was no risk of exposure to Se.

加利福尼亚北部海湾的中生鱼类太平洋无尾鳕（Merluccius productus）组织中汞和硒的生物富集以及对人体健康的风险评估。

为了评估危害消费者的健康风险，对来自加利福尼亚北部海湾的62例产Merluccius菌的标本的肌肉，肝脏，性腺，肾脏和g中的汞和硒进行了测量。汞在组织中的平均值±置信区间（95％置信水平）浓度（mg kg-1湿重）为：性腺（1.01±0.25）>肌肉（0.44±0.06）> g（0.29±0.04）>肾脏（0.20± 0.07）>肝脏（0.02±0.004）。汞的性别差异无统计学意义。硒的平均浓度分布（mg kg-1湿重）为：肾脏（4.61±1.27）>肝脏（1.66±0.22）>性腺（1.66±0.75）> ill（0.86±0.04）>肌肉（0.40±0.09））。性腺中的硒显示出性别之间的显着差异（女性>男性）。与总长度呈正显着正相关（p <0。05）和总重量（p <0.05）在同一组织中发现了两种形态学变量：肌肉中的Hg，肌肉中的Se和肝脏中的Se。在所有组织中都发现硒比汞过量（摩尔比：硒：汞> 1）。对食用肌肉和性腺的人类的危险情商健康风险指数进行了评估。成人和儿童的推荐汞安全摄入量分别是每周10.0和33.0 g肌肉；对于性腺，成人和儿童每周食用35.0克和14.0克，没有汞危险。没有暴露于硒的风险。对食用肌肉和性腺的人类的危险情商健康风险指数进行了评估。成人和儿童的推荐汞安全摄入量分别是每周10.0和33.0 g肌肉；对于性腺，成人和儿童每周食用35.0克和14.0克，没有汞危险。没有暴露于硒的风险。对食用肌肉和性腺的人类的危险情商健康风险指数进行了评估。成人和儿童的推荐汞安全摄入量分别是每周10.0和33.0 g肌肉；对于性腺，成人和儿童每周食用35.0克和14.0克，没有汞危险。没有暴露于硒的风险。
