Mercury, cadmium, and selenium contents were quantified in sharks Mustelus henlei, M. californicus, Sphyna zygaena, and Isurus oxyrinchus, which represent important fishery resources in the western coast of Baja California Sur, Mexico. Sample compliance estimations with Mexican dietary standards and human health risks, according to provisional tolerable weekly intake (PTWI), were provided for critical population sectors, including young children, pregnant/nursing women, and adults. The estimated weekly intake was limited to 1.52 kg of M. californicus, 1.35 kg of S. zygaena, 0.5 kg of I. oxyrinchus, and 2.42 kg of M. henlei. Likewise, the Hazard Quotient (HQ) <1 and Hazard Index (THI) <1 were within safe limits; therefore, there will be no chronic noncarcinogenic health hazards in the short or long term. Carcinogenic risk is a concern mainly for children, and the most appropriate approach is for children to consume no >0.5 kg of shark meat per week.

“墨西哥暴露于汞、硒和镉的鲨鱼消费者的风险评估”


对鲨鱼 Mustelus henlei、M. californicus、Sphyna zygaena 和 Isurus oxyrinchus 中的汞、镉和硒含量进行了量化，它们是墨西哥南下加利福尼亚州西海岸的重要渔业资源。根据临时每周可耐受摄入量 （PTWI），为关键人群部门（包括幼儿、孕妇/哺乳期妇女和成人）提供了对墨西哥膳食标准和人类健康风险的样本依从性估计。估计每周摄入量限制为 1.52 公斤加利福尼亚分枝杆菌、1.35 公斤 S. zygaena、0.5 公斤 I. oxyrinchus 和 2.42 公斤 M. henlei。同样，危险商数 （HQ） <1 和危险指数 （THI） <1 在安全范围内;因此，短期或长期都不会有慢性非致癌健康危害。致癌风险主要是儿童关心的问题，最合适的方法是让儿童每周食用不超过 >0.5 公斤的鲨鱼肉。
