Abstract

|
|
In order to investigate the effectiveness of measurement of zinc protoporphyrin(ZPP) in whole blood in the health provision of lead workers, 344 male lead workers working in 4 different lead using industries were selected.
The parameters chosen for this study were ZPP in whole blood, blood lead ( PBB ), 6-aminolevulinic acid in urine (ALAU ), hemoglobin (HB ), work duration of each workers & their working condition.
The results obtained are as follows:
1. Blood ZPP was highly correlated with blood lead among various indices of lead absorption. There was no difference of correlation coefficient between ZPP & LOGZPP with blood lead.
2. The regression equation of LOGZPP on blood lead(PBB) was LOGZPP = 2.61+0.047 PBB
3. The slope of regression of LOGZPP on PBB of longer work duration was steeper than that of short work duration group. This could be explained by the chronic effect of lead on heme precursors.
4. It is highly recommended that blood ZPP could be used as a screening index of biological monitoring of lead workers.
