The airborne levels of carcinogenic trace metals lead (Pb), cadmium (Cd),
arsenic (As) and nickel (Ni) were evaluated in the Orthopaedic Operation Theater (OOT),
Orthopaedic Wards (OW) and Orthopaedic Emergency Rooms (OER) of six hospitals, in
Lahore, Pakistan. Overall, the average levels of Cd, As and Ni (31, 20, and 37 ng/m3
) were
lower indoors as compared to outdoors (39, 21, and 51 ng/m3
) except Pb. The high indoor
levels of Pb (113 ng/m3
) as compared to outdoors (85 ng/m3
) suggested pronounced indoor
sources. The average indoor-outdoor (I/O) ratio for the Pb, Cd, As and Ni were 1.34, 0.94,
0.99 and 0.79 respectively. The results showed that indoor air in the hospitals were affected by
the common effects of indoor (wall paints, indoor equipment, environmental tobacco smoke)
and outdoor (dust, soil and fuel combustion) sources. The hospitals were located on busy roads,
where high vehicular emissions probably emit trace metal pollutants.
