Abstract

Mercury (Hg) is mainly incorporated into humans through the consumption of contaminated foods. Mercury was measured and the methyl-Hg (MeHg) concentration was estimated in canned mollusks sold in northwestern Mexico to assess the health risk to consumers. Five mollusk types were considered: oysters, clams, octopuses, mussels, and squids. The Hg concentration of mussels was significantly (P < 0.05) lower than those of the other bivalves (oysters and clams) and cephalopods (squids and octopuses). The average Hg concentration in bivalves (0.013 mg·kg–1) was significantly (P < 0.05) lower than that of cephalopods (0.018 mg·kg–1). The estimated MeHg concentrations were also lower in bivalves than in cephalopods. Based on our results, no health risk is associated with the consumption of canned mollusks that are sold in northwestern Mexico. The Hg and MeHg concentrations followed the order of octopuses > squids = clams > oysters > mussels. The Hg and MeHg concentrations in the mollusks evaluated in this study were below the maximum permissible limits for human consumption in Mexico.

墨西哥西北部出售的国产和进口双壳类和头足类罐头中的汞浓度

汞主要通过食用受污染的食物而被人体吸收。对墨西哥西北部出售的软体动物罐头中的汞进行了测量，并估计了甲基汞浓度，以评估消费者的健康风险。考虑了五种软体动物类型：牡蛎、蛤蜊、章鱼、贻贝和鱿鱼。贻贝的汞浓度显著低于其他双壳类（牡蛎和蛤蜊）和头足类（鱿鱼和章鱼）（P<0.05）。双壳类动物的平均汞浓度（0.013 mg·kg–1）显著低于头足类动物（0.018 mg·kg-1）（P<0.05）。估计的双壳类动物的甲基汞浓度也低于头足类动物。根据我们的研究结果，食用墨西哥西北部出售的软体动物罐头没有健康风险。汞和甲基汞的浓度依次为章鱼>鱿鱼=蛤蜊>牡蛎>贻贝。本研究中评估的软体动物中的汞和甲基汞浓度低于墨西哥人类消费的最大允许限值。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
