URINE LEAD LEVELS IN SERVICE STATION ATTENDANTS EXPOSED TO TETRAETHYL LEAD
Abstract
Introduction: It has been pointed out that the hazard associated with the exposure to tetraethyl lead is Quite different from exposure to inorganic lead compounds, and that the measurment of urinary lead is the best indicator of tetraethy lead absorption and hence its environmental control.
Methods: Urine total lead concentrations in service station attendants in Isfahan city after extraction were determined by graphite furnace atonic absorption spectrophotometry.
Results: Average total urine lead concentration was (69.75±14.52 mg/l) (range 43 - 105 mg/l).
Discussion: All workers has urine total lead levels below the Biological threshold limit value of 150 mg/l. In addition total lead excretions did not correlate with exposure duration and age and also with individual customs such as personal hygiene and smoking habit. In general, on the basis of the present study results and current data it seems that urine total lead is not a sensitive and specific indicator for exposure to tetraethyl lead.
