ABSTRACT
Objective To develop a method to determine lead in the whole blood with graphite furnace atomic absorption spectrometry.Methods The whole blood was diluted with mixing matix modifiers [5.0 g/L NH4H2PO4+1.0 g/L Tritonx-100+2.0 ml/L HNO3],then the samples were automatically injected and the blood lead level was determined with Zeeman graphite furnace atomic absorption spectrometer.Results There was significant linear relation between absorbance and lead level in the range of 0-40 ?g/L(r=0.998 2),the relative standard deviation(RSD)was 5.5%-12.2%,the recovery rate was 90%-106%,detection limit was 1.1 ?g/L.Conclusion This method is characterized by reliable result,convenient procedure as well as lower pollution.The test result of whole blood lead level in more than 600 occupational lead exposed people with this method is satisfactory.
