The concentrations of Cr, Pb, Zn, Cu, Ni and Cd wereanalyzed by Atomic Absorption Spectrophotometer in thescalp hair of professional male autodrivers who areoccupationally exposed to the vehicular/industrialpollutants in the industrial city of Coimbatore, TamilNadu. The unwashed hair samples when compared with thewashed hair showed a significantly higher levels of Cr,Zn and Pb. The correlation coefficient showed a strongmutual dependence on the scalp hair of the exposedindividuals and no correlation was found among the tracemetals except for Ni–Pb and Ni–Cd. The results ingeneral showed a positive exogenous contribution of allthe analyzed industrial trace metals. The drivers who are occupationally exposed to vehicular/industrial pollution are at risk. 相似文献
