Abstract/Summary

A modified flame atomic absorption spectrophotometric method employed for the determination of cadmium and lead in mussel tissue is validated. Performance characteristics and limitations of the method are investigated. The method was found to be suitable only for cadmium analysis as revealed by the accuracy and precision tests. The validated method when applied to mussel samples collected from five sampling sites in Bacoor Bay showed cadmium and lead levels to be 0.2042 + - 0.06129 ppm and 1.033 + - 0.1269 ppm, respectively. Variations in tissue metal concentrations among the sites were also investigated using One-Way Analysis of Variance. Significant differences were observed among the sites for both metals.
