Determination of Lead and Cadmium in Human and Animal Blood Samples by Flameless Atomic Absorption Spectrometry with Rapid Standard Addition

A method for the determination of harmful elements of lead and cadmium in the human and animal blood samples by flameless atomic absorption spectrometry with rapid standard addition is reported in this paper. The detection limits of the method are 2.00 μg/L for Pb and 0.30 μg/L for Cd. The recovery of the method are 99.5%～101.2% for Pb and 99.7%～101.3% for Cd with the precision of 0.95%RSD for Pb and 2.18%RSD for Cd. The method provides the advantages of high sensitivity and precision, simple sample preparation, calibration and result calculation. The method is suitable for general survey of Pb and Cd in human blood.
