Background: Isfahan is one of the most polluted cities in Iran due to heavy teraffic and huge industrial activities.Today, using human nails has been considered as biological indicatorfor expossure to heavy metals. This research was carried out in order to use the nails as bio-marker for air pollution in Isfahan compared to Chadegan city which has clean air.Methods: Two groups of 65 people from each city with age range of 5-50years old covering both women and men were selected. Then 1 gram of fingernail from each of them was collected. After preparation and digestion of the samples, the concentration of lead in thesamples was determined by atomic absorption spectroscopy.Findings: ANOVA analysis of the data related to age, sex, job and exposure to cigarette smock in the subjects showed that the selected population in two cities is completely homogeneous and similar. Significant differences between the average concentration of lead in the nails of Isfahan residences (0.1037 mg/g) and Chadegan residences (0.0875 mg/g) were observed (P< 0.001).Conclusion It was found that significant difference between the average concentrations of lead in the nails of subjects is related to the place of residences t and their exposure to environmental contaminants including air pollution from industries in Isfahan which is effective on concentration of lead in the nails samples.Key Words: Nails, Lead, Bio Indicator, Traffic, Air Pollution, Isfahan, Chadegan
