Comparative Study on Determination of Uric Lead By Different Methods

We measured the level of uric lead in workers exposured and nonex posured lead by DPSA,GFAAS and DCM.The basic parameters of the three methods demonstrated that sensitivity and precision of DPSA and GFAAS excelled that of DCM,but the linear range of DPSA and GFAAS are more narrow than that of DCM. All of The three methods had excellent accuracy(paired t-test P>0.05).The results showed the different of the three methods no significant.
