Abstract:
A method based on laser induced breakdown spectroscopy (LIBS) 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. Detection limits by LIBS are 25
parts per million (ppm) for Pb and 100 ppm for Cu, values that are below the maximum permissible levels of
some international standards. Application of LIBS detection allows the development of portable instruments for
contamination control of edible fish.
