Persistent organic pollutants (POPs) in fish from two coastal lagoons of the central Mexican Pacific
ABSTRACT Mexico has a great variety of aquatic ecosystems; however, most of them present significant contamination levels. Despite the efforts to monitor toxic and bioaccumulative persistent pollutants, they are still insufficient and outdated data from Mexican coasts, especially in polychlorinated...

It was found that the potential risk for fishing communities is considerably higher and correlates to the rate of fish consumption, highlighting their vulnerability to these contaminants.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Valparaíso.
