Con el objeto de contribuir al conocimiento de los procesos de bioacumulación y biomagnificación de metales en estuarios tropicales, se tomó la bahía de Cartagena como modelo del flujo de mercurio en las redes tróficas. Se realizaron cinco muestreos en cinco estaciones y se recolectaron muestras de sedimentos, seston, plancton y peces. A todas las muestras se les determinó la concentración de mercurio total (HgT) y metil mercurio (MeHg). Los resultados sugieren que incluso a bajas concentraciones de HgT en sedimentos (0,18 ± 0,01 μg/gp.s), y en seston (0,16 ± 0,002 μg/gp.s), el flujo de mercurio se da en todos los niveles tróficos de los organismos muestreados. Se encontró una concentración de HgT en plancton de 0,32 ± 0,005 μg/gp.s; en pe...
