Determination of cadmium and lead content in muscle, liver and kidney of slaughtered cattle in Shahrekord using GFAAS

The cadmium and lead content of muscle, liver and kidney of 40 cattle slaughtered in Shahrekord were investigated. They were determined by graphite furnaces atomic absorption spectrometry (GFAAS) after wet digestion of the samples. An analytical quality control program was carried out during the study. The mean and median cadmium of the processed samples were 0.002, 0.0015 for muscle, 0.0299 and 0.0193 for liver, 0.0652 and 0.0386mg/kg for kidney. Cadmium values in samples did not exceed the acceptable maximum threshold established in the European Commission. The mean and median lead of the processed samples were 0.0489 and 0.0395 for muscle, 0.2454 and 0.2270 for liver, 0.3239 and 0.3300mg/kg for kidney. Lead content from 15% of muscles, 7.5% from livers and 12.5% from kidneys exceeded the acceptable maximum threshold established in the European Commission. As a consequence, it was values in muscle, liver and kidney that can be related to animal age (P<0.05). Cadmium and lead comparison between two the sexes were not statistically significant. According to the results of this study, fortunately, the mount of toxic elements of cadmium and lead in animal products in Shahrekord is lower than acceptable maximum throshold established in the European Commission.
