Abstract:  To assess the risk associated with cement plant stack emissions and its toxic component, it was planned to locate the present status of respiratory tracts of subjects related to the cement plant and its environment. The work reported describes estimations of selected toxic metals (Pb, Cr, Cd, Co, Ni, Mn and Zn) in a total of 92 samples of respiratory tract washout obtained from diagnosed cases of respiratory ailments in a slag based cement plant environment in central India. Bronchial washout samples were collected from the workers and non-workers of the plant and analyzed for Mn, Pb, Cr, Ni, Zn, Co and Cd using Atomic Absorption Spectrophotometer. Results have shown greatest impact on the workers compared to the residents of the township and subjects who are unrelated to cement plant and its environment. Although, all the elements found in respiratory tracts are good in concentration but Mn, Ni, Cr and Pb, showing somewhat higher tendency to be deposited in human respiratory tract than Zn and Co. Order of occurrences of the elements, analyzed in respiratory tract is: Mn > Pb> Cr > Ni > Zn > Co > Cd. The result shows slightly higher susceptibility for respiratory damage in female.
