Hair Lead Concentration In Nakhlak Lead Miners Versus Control Group

Introduction. Lead poisoning is a major problem in environmental health. Exposure can occur via air, soil, food and water. Occupational exposure is the most common source of lead poisoning in adults. Lead miners are exposed to an additional source of poisoning in long term. Hair analysis may be used to evaluate chronic lead toxicity. This study compare the hair lead concentration in Nakhlak lead miners and Mohammadieh people who live 130 km far from the lead mine. Methods. Hair samples from 24 Nakhlak lead miners and 26 adult men of Mohammadieh village were gathered, washed by detergent and distilled water and dissolved by wet digestion. Lead concentrations of the samples were measured by flame atomic absorption spectroscopy. Results. There was a significant difference between hair lead concentration of Nakhlak lead miners and Mohammadieh people (P
