[Study on hair Hg and Pb content distribution of traffic polices, Guilin].
95 hair samples from traffic polices and 110 hair samples from ordinary people were collected from 6 areas of Guilin, China, and Hg, Pb contents in hairs were determined. The result shows that the heavier the traffic was, the higher hair Hg, Pb contents of traffic polices are. Hair Hg, Pb contents of traffic polices also increase with their working time. Average hair Hg, Pb contents of outdoor polices are higher than those of indoor polices. The average hair Hg content (1.340 microg x g(-1)) of traffic polices is 1.74 times as high as the Chinese average value (0.77 microg x g(-1)), while the average hair Pb content (2.877 microg x g(-1)) is below the Chinese average value (6.60 microg x g(-1)). The use of unleaded petrol reduced the air Pb pollution, but Hg pollution still exists. The average hair Hg content (1.504 microg x g(-1)) in male traffic polices is higher than that (1.176 microg x g(-1)) of female traffic polices,while the average hair Pb content (2.852 microg x g(-1) in male traffic polices lower than that (2. 902 microg x g(-1)) of female traffic polices.
