Mercury, cadmium, lead, arsenic, copper and zinc concentrations in albacore, yellowfin tuna and bigeye tuna from the Atlantic Ocean

The concentrations of Hg, Cd, Pb, As, Cu and Zn were determined in 67 tuna samples from the Atlantic Ocean, in order to determine the concentrations present in different species and to evaluate possible risks for human health as a consequence of the consumption of these products. The maximum permiss...

The maximum permissible levels of Hg, Cd and Pb in foodstuffs are established by Commission Regulations (EC) 466/2001 and 78/2005.

Se determinaron las concentraciones de Hg, Cd, Pb, As, Cu y Zn en 67 muestras de atunes procedentes del Océano Atlántico, con el fin de conocer las concentraciones existentes en las diferentes especies y evaluar los posibles riesgos para la salud humana derivados de su consumo. Los límites máximos de Hg, Cd y Pb en productos alimenticios están regulados en los Reglamentos CE 466/2001 y CE 78/2005. Las especies estudiadas fueron el atún blanco o bonito del norte (Thunnus alalunga), el rabil (Thunnus albacares) y el patudo (Thunnus obesus). Las tres especies muestran diferencias en las concentraciones de los metales analizados. Las concentraciones máximas de Hg obtenidas en las muestras de atún blanco y rabil se encuentraron muy alejadas del límite para consumo humano fijado en el Reglamento Comunitario para este elemento (1.0 mg kg–1 peso húmedo). Sin embargo, algunos ejemplares de patudo sobrepasaron dicho límite. Para el resto de los metales legislados, los valores son muy inferiores al límite. En las tres especies las concentraciones de Hg aumentan con la longitud de los peces; sin embargo, para el resto de los elementos estudiados las relaciones entre concentraciones y tallas no están claramente definidas. 2006-08-21 2021-06-03T03:55:14Z 2021-06-03T03:55:14Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1083 10.7773/cm.v32i22.1083 https://hdl.handle.net/20.500.12930/7410 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1083/1924 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 2B (2006); 439-445 Ciencias Marinas; Vol. 32 Núm. 2B (2006); 439-445 2395-9053 0185-3880
