Trace elements are analyzed in the human scalp hair to assess the extent of body burden of pollution. The levels of seven elements (Cd, Cr, Cu, Mn, Ni, Pb and Zn) were determined in the hair of fishermen from Pondicherry, students and businessmen from Madras and non-mining workers from Neyveli lignite open mine. When compared between them, significantly high concentrations of Cd in the non-mining workers from Neyveli and Pb in both the students and businessmen from Madras were observed, thereby indicating environmental source of Cd and Pb pollution. The low Zn level was observed in the fishermen indicating their low nutritional source. In addition to the different residential areas, age, diet, smoking habit and family income of subjects are other factors influencing the concentrations of elements in the hair.
