Persistent organic pollutants (POPs) in fish from two coastal lagoons of the central Mexican Pacific

Mexico has a great variety of aquatic ecosystems; however, most them present significant contamination levels. Despite the efforts to monitor toxic and bioaccumulative persistent pollutants, they are still insufficient outdated data from Mexican coasts, especially in polychlorinated biphenyls (PCBs) polyaromatic hydrocarbons (PAHs), due number bodies that have received little or no attention. In this regard, Pacific's coastal zones their ecosystems monitoring PCBs PAHs biota is critical because it allows us estimate potential risk human health. This work aimed determine total concentration (ΣPCBs) (ΣPAHs) muscle fish collected two lagoons central Pacific non-carcinogenic ratio (HQ) based on monthly per capita consumption national associated with fishing communities Mexico. It was found for considerably higher correlates rate consumption, highlighting vulnerability these contaminants.
