Abstract | ||
Over the last three decades, there has been an increasing awareness of environmental and occupational exposures to toxic or potentially toxic trace elements. Chemical investigation was conducted into the concentrations of Lead in scalp hair samples of some selected workers who work at occupational settings which expose them to metal contaminants. The measured concentrations of Pb was compared with the level in workers who were unlikely to be occupationally exposed to the studied metal contaminants. Traces of Lead was found in all the samples analyzed. However the concentration of the studied metals was higher in occupationally exposed workers than those who was not likely to be occupationally exposed to the metals. The objective is to assess the concentrations of lead(pb) in scalp hair workers who are exposed to metal hazards of their occupational settings in petrol station in Baghdad and compared with those who are not likely to be exposed to the metal. The samples were randomly selected from thirty workers who work at three petrol station located in Bagdad. Twenty samples were also collected from individuals who were virtually not occupationally exposed Pb. The metal quantitative analysis using atomic absorption spectrophotometer. The range concentration of lead obtained from scalp hair workers occupationally exposed individuals were found to be 0.03-0.2mg/L compared with lead in scalp hair workers unexposed to metal contamination 0.009-0.013mg/l . The mean(± SD) (0.106± 0.064)mg/L was highly significantly increased in scalp hair of the occupationally exposed as compared to unexposed to metal(0.01±0.001)mg/L, p<0.005.There was highly significant positive correlation between the concentration of pb and the duration of exposed to metal( r=0.89 ,p<0.0005). The results of this study have revealed that the average concentration of lead in human scalp hair of occupationally exposed workers increases with increased number of years spent by an individual at the work place. | ||
