The samples of ambient air collected from six different sites of the city during three different seasons on glass fibre filter papers were estimated for selected metals. The maximum value of Pb (0.191 microg m-3), Cd (0.015 microg m-3), Zn (0.198 microg m-3), Ni (0.582 microg m-3) and Cu (0.396 microg m-3) was observed at Hissar road during winter season. The minimum value of Pb (0.006 microg m-3), Cd (not detected), Zn (0.002 microg m-3), Ni (0.003 microg m-3) and Cu (0.002 microg m-3) was observed at University Campus during monsoon season. These values were however below the permissible limits. Sample of 50 people each was taken up from both low and high polluted sites. The significant difference at P<0.001 was observed in Cu, Zn, Pb, Ni and Cd in blood samples of subjects residing at low and high polluted area.
