Abstract
The validity of laboratory tests was tested on 317 workers occupationally exposed to lead. The increase in urinary elimination of lead, coproporphyrin and delta-amino levulinic acid (ALA) was evident. The determination of ALA proved to be the must sensitive test, suitable to define the quantity of metabolically active lead in the organism. ALA concentrations were highly correlative with urinary lead levels (r = 0.91). It is concluded that the determination of ALA to creatinine ratio (ALA index) has no advantage over the simple expression of ALA in mg/l or in mg/100 ml urine.
