Resumen:
A method based on Laser Induced Plasma Spectroscopy for monitoring lead and copper accumulation in edible fish, particularly ?tilapia del Nilo? (Oreochromis niloticus) is presented. The capability of this analytical method is compared with results obtained by atomic absorption spectrometry (AAS). Detection limits by LIBS is 25 ppm for Pb and 100 ppm for Cu, values that are in the range of the maximum permissible levels of international standards. Application of LIBS detection allows the development of portable instruments for contamination control of edible fish.
