title: Biological monitoring of occupational exposure to lead with a zinc protoporphyrin (ZPP) meter.
abstract: Recent literature dealing with biological monitoring of people exposed to lead at work is reviewed. The widespread trend to regard lower levels of lead in air or in the blood of workers as acceptable or as recommended upper limits is discussed. Based on practical experience over a 6-month period, it is concluded that the zinc protoporphyrin (ZPP) test is an adequate, convenient and inexpensive screening method for monitoring workers exposed to lead in a motor care manufacturing plant.
