title: Absorption of lead in Tehran traffic policemen.
abstract: In this study 228 traffic policemen and 68 policemen engaged in office duties were studied for lead absorption. The average value of blood lead of traffic policemen (29.52 +/- 7.78 micrograms/100 mL) in the city of Tehran was significantly (p less than 0.01) higher than for the policemen in office duties (21.74 +/- 5.63 micrograms/100 mL). No correlation between blood lead level and age and/or length of occupation was found. The most reasonable explanation for the findings of this study is that lead emission from motor vehicles is causing this effect.
