عنوان انگلیسی HAIR LEAD CONCENTRATION IN NAKHLAK LEAD MINERS VERSUS CONTROL GROUP
چکیده انگلیسی مقاله 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 < 0.001). The mean of lead concentrations were 52.43±27.7 µg/g (mean ± SD) and 17.32±3.43 µg/g hair of the lead mine workers and the Mohammadieh people, respectively. There was also a significant regression between the number of exposure years and the lead concentration of hair in Nakhlak lead miners (P < 0.001, r=0.8). Discussion. Presence of lead compounds in work environment especially in the air may be an important factor for the difference between hair lead concentration of Nakhlak lead miners and Mohammadieh people. However, the hair lead concentration in Mohammadieh people is also reasonably high. It means that these people are also exposed to lead through the other sources e.g. food, soil, water and air.
