Samples of air from the work place environments of selected industries were collected. These samples were analysed for carbon monoxide (CO), sulphur dioxide (SO2) and heavy metals like, Lead(Pb), Copper(Cu), Chromium (Cr), Cadmium (Cd), Zinc (Zn) and Iron (Fe), by standard methods. The results are presented and discussed. The level of these elements varied in the range of 0.79-1.43, 0.07-0.5, 0.22-130, 0.001, 3.7-25, 93.60 and 24.6-59 mu g/m(3) for Pb, Cr, Cu, Cd, Zn and Fe respectively in the air samples of various industries investigated.
