The purpose of this study is to evaluate the health effect of heavy metal pollution in air pollutants on traffic policemen. This study will facilitate the scientific evaluation of health status of traffic policemen. PM samples were collected from industrial area, congested traffic area and residential area respectively in Nanchang City, and the concentrations of heavy metals were analyzed. The traffic policemen were examined through chest X-rays. The total of 637 urine samples and 142 blood samples have been collected, and the concentrations of Pb in samples were detected. Vehicle flux data of Nanchang City were collected from the Department of Transport's Traffic Management. Statistic analyses were carried out by statistics software of Excel 2003 and SPSS20.0, and the health effect of heavy metal pollution of PM on the traffic policemen was evaluated. The discharge of pollutants from enterprises is an important reason for the high content of heavy metals in urban air pollution. With the rapid growth of urban traffic flow, Bayi Bridge becomes an important transportation hinge in Nanchang City, and the bidirectional traffic flow rate through the bridge at peak hours reached 99 vehicles per minute. The latent hazard of occupational harm on the traffic policemen caused by automobile exhaust is increasing. The concentration of Pb in the urine and blood samples from traffic policemen working in Nanchang City was 268.310 ± 177.031 and 22.873 ± 21.137 μg/L, respectively. Both results (2.04% of Pb in urine and 18.31% of Pb in blood) exceeded the highest limit of observed occupationally outdoor workers. This study provides an initial contribution for the assessment of city air pollution, esp. the health effect of heavy metal (Pb) pollution on traffic policemen.
本研究旨在评估空气中空气污染物重金属污染对交通警察的健康影响。这项研究将有助于科学评估交通警察的健康状况。本研究分别从南昌市工业区、交通繁忙区和居民区采集 PM 样品，并分析重金属浓度。对交通警察进行了胸部 X 射线检查。共采集了 637 份尿液样本和 142 份血液样本，并检测了样本中 Pb 的浓度。南昌市交通局收集了该市的车辆流量数据。采用 Excel 2003 和 SPSS20.0 统计软件进行统计分析，评价了 PM 中重金属污染对交通警察的健康影响。企业污染物排放是城市空气污染重金属含量高的重要原因。随着城市交通流量的快速增长，八一桥成为南昌市的重要交通枢纽，高峰时段通过大桥的双向交通流量达到每分钟 99 辆。汽车尾气对交通警察职业危害的潜在危害日益增加。南昌市交通警察的尿液和血液样本中 Pb 的浓度分别为 268.310±177.031μg/L 和 22.873±21.137μg/L。这两个结果（尿液中 Pb 的 2.04%和血液中 Pb 的 18.31%）均超过了观察性户外工作者的最高限量。本研究为城市空气污染评估，特别是重金属（Pb）污染对交通警察的健康影响评估提供了初步贡献。
