En el Golfo de Mxico la contaminacin de los ecosistemas marinos por metales pesados se da principalmente por las actividades industriales, ocasionando problemas de conservacin de los recursos naturales ms difciles de afrontar. Dentro de los organismos utilizados como bioindicadores se encuentran a los peneidos, que por sus hbitos de vida y alimenticios, absorben grandes cantidades de metales pesados. Estos organismos son uno de los recursos ms importantes con alto valor mundial y son exportados a E.U.A y Japn. Pero al ser consumidos por los humanos pueden ser nocivos para su salud si contienen elevadas concentraciones. El objetivo fue determinar la concentracin de metales pesados en camarn caf colectados en la laguna de Tampamachoco al norte de Veracruz. Se analizaron cuatro metales (Cd, Cr, Pb y Cu) mediante espectrofotometra de absorcin atmica. Las concentraciones mximas se dieron en Cd: 1.55 mg/kg, Cr: 2.32 mg/kg y Cu: 18.625 mg/kg. El Pb no fue detectado por el espectrofotmetro (0.25 mg/Kg), el Cd rebas el nivel mximo permisible en crustceos (0.5 mg/kg). Mientras que el Cr y Cu no rebas el lmite permisible por la FDA y la FAO (Cr: 12 mg/kg, Cu: 32.5 mg/Kg).
