    Abstract:
    OBJECTIVE: To compare and evaluate anodic striping voltammetry (ASV) with graphite furnace atomic absorption spectrophotometry (GFAAS) for blood lead analysis. METHODS: These two methods were used to analyze same samples of three kinds of blood (cattle blood, rat blood & human blood) at the same time. The practicability and reliability of the results were evaluated by the statistic analysis. RESULTS: Limits of detection (LOD) for ASV and GFAAS were 5.3 microg/L and 0.045 microg/L. Limits of quality (LOQ) were 17.8 microg/L and 0.15 microg/L for ASV and GFAAS. The results that three kinds of blood samples were analyzed by these two methods were in high correlation after t test (P > 0.05). CONCLUSION: The data demonstrated that the ASV method could be in the complete conformity to GFAAS for different kinds of blood samples in lead analysis. The results showed that the sensibility of GFAAS was better than that of ASV, but the ASV showed a marked performance in stability, ease of operation and precision as well as GFAAS. GFAAS was suitable for the scientific research as ASV for a clinic.
