The contents of Zn, Cu, Cd, Pb, Fe, Al and Ni in the muscle tissue of Cancer polyodon from Caldera, Calderilla, Inglesa, and Salada bays (Atacama, Chile) were quantified. The results were compared with similar studies by other authors and with the national and international regulatory standards for heavy metal contents in crustaceans for human consumption. In increasing order, the metal contents in C. polyodon were: Cd< Ni< Cu< Pb< Zn

dc.descriptionEl contenido de Zn, Cu, Cd, Pb, Fe, Al y Ni fue analizado en tejido muscular de Cancer polyodon en las bahías de Caldera, Calderilla, Inglesa y Salada (Atacama, Chile). Los resultados fueron comparados con estudios similares desarrollados por otros autores y la normativa de carácter nacional e internacional relacionada con el contenido de metales pesados en crustáceos para consumo humano. El orden de abundancia de los metales analizados en C. polyodon fue Cd<Ni<Cu<Pb<Zn<Fe<Al. Las concentraciones medias de Cd, Pb, Fe y Al fueron más elevadas en bahía Salada, mientras que el Cu y Ni lo fue en bahía Caldera y el Zn en bahía Inglesa. Todos los metales, con excepción de Cu, presentaron diferencias significativas (P < 0,05) entre las bahías analizadas. De los siete metales analizados en C. polyodon las concentraciones de Pb, Fe y Al presentaron niveles más elevados que los reportados para otros sistemas costeros. Las concentraciones de Cu (excepto bahía Calderilla), Cd (excepto bahías Caldera e Inglesa) y Pb sobrepasaron los valores permitidos por la normativa nacional e internacional, lo que sugiere que la presencia de estos metales en C. polydon representa un potencial riesgo para la salud humana. es-ES

The results were compared with similar studies by other authors and with the national and international regulatory standards for heavy metal contents in crustaceans for human consumption. In increasing order, the metal contents in C. polyodon were: Cd< Ni< Cu< Pb< Zn<Fe< Al. Mean concentrations of Cd, Pb, Fe and Al were highest in Salada Bay: Cu and Ni were highest in Caldera Bay; and Zn was highest in Inglesa Bay. All the metals except Cu differed significantly (P < 0.05) among the analyzed bays. Of the seven metals analyzed, Pb, Fe, and Al concentrations in C. polyodon were higher than those reported for other coastal systems. Concentrations of Cu (except Calderilla), Cd (except Caldera and Inglesa), and Pb exceeded the threshold values indicated by the national and international standards, suggesting that the presence of these metals in C. polyodon represents a potential risk for human health.en-US
