Heavy metals in sediment and fish from two coastal lagoons of the Mexican Central Pacific

ABSTRACT The present work analyzed the concentration of As, Cd, Pb, and Hg in sediment and the Hg concentration in fish muscle from two coastal lagoons in the states of Jalisco (Barra de Navidad Lagoon) and Colima (Cuyutlán Lagoon), Mexico. Both lagoons showed relatively low levels of metal contamin...

Both lagoons showed relatively low levels of metal contamination and potential health risk compared to other Mexican areas. A non-carcinogenic hazard quotient (HQ) was determined. As (10.7 ± 1.3 - 25.4 ± 3.1 µg g-1) and Pb (42.7 ± 4.2 - 123.9 ± 14.7 µg g-1) concentrations exceeded the permissible levels, otherwise for Hg and Cd were below the limits.
