Individual variation in response to lead exposure : a dilemma for the occupational health physician
Subclinical lead poisoning with no clinical symptoms is a dilemma for the occupational health physician. He is supposed to assess when and how to treat workers at risk mainly by the results of biological monitoring.The aim of this study was to demonstrate different responses of biological indices in 50-lead-exposed workers who have been working in the same plant of lead pigment production factory. Twenty-one have normal, that is, permissible blood lead concentrations (PbB), erythrocyte protoporphyrin (EP) and aminolevulinic acid (ALAD) measured during regular periodic examination (group 1). No differences between two two measurements were found, although they were continouosly working with lead. In 18 of the 50 workers (group 2). PbB and EP concentrations increased, whereas ALAD activity decreased;those parameters improved after a 3- to 6-month cessation of lead exposure. Seven of the 50 workers also had altered values of biological indices, but their condition improved spontaneously without cessation of lead exposure (group 3), while in the remaining four workers, elevated, concentrations of biological indices did not change during the observation period. The reasons for such discrepancies and indications for chelation therapy are discussed.
