ABSTRACT:

Hair has been used as a diagnostic tool for assessing trace element concentrations in workers of locomotive workshop occupational exposed to elemental pollution.In the present study, 120 bair samples were collected personally from the workers of locomotive workshop, situated in Western Rajasthan, Ajmer. All the collected hair samples were thoroughly washed, acid digested and then metal concentrations were determined using atomic absorption spectrophotometer with graphite furnace and air acetylene flame. The other parameters viz wavelength, slit width, lamp current etc. were set separately for each metal. It was found that the mean concentration of chromium (Cr), manganese (Mn), iron (Fe) and nickel (Ni) were significantly high in the hair samples of exposed workers than controls.

KEYWORDS:

spectrophotometer; thoroughly; occupational elemental
