Abstract

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 ?g m^-3), Cd (0.015 ?g m^-3), Zn (0.198 ?g m^-3), Ni (0.582 ?g m^-3) and Cu (0.396 ?g m^-3) was observed at Hissar road during winter season. The minimum value of Pb (0.006 ?g m^-3), Cd (not detected), Zn (0.002 ?g m^-3), Ni (0.003 ?g m^-3) and Cu (0.002 ?g 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.
