  • Title: Lack of relationship between hair lead levels and some usual markers (blood lead levels, ZPP, urinary ALA-D) in occupationally exposed workers.

    Abstract:
    Blood and hair samples collected from 54 male workers occupationally exposed to lead were assayed for this metal by graphite furnace atomic absorption spectrophotometry. Blood ZPP and urinary ALA-D were also determined for most subjects tested. Blood and hair lead concentrations (PbB and PbH) ranged from 100 to 770 ng/ml (10 to 77 micrograms/100 ml) (mean +/- SD: 384.6 +/- 143.4 ng/ml (38.46 +/- 14.34 micrograms/100 ml)), and from 3 to 243 ng/mg (mean +/- SD: 102.4 +/- 72.6 ng/mg), respectively. No correlation was observed between the PbH and PbB values, nor between PbH and ZPP or ALA-D values. Neither hair coloration nor subjects' age were related to PbH levels. Results are discussed in the light of the existing literature.
