Blood lead level, haemoglobin concentration (Hb) and urinary delta-aminolevulenic acid (ALA) were determined for 126 traffic policemen and a control group of 50 office-based policemen of Cairo city. Mean blood lead level and Hb of traffic policemen were significantly higher than those of the controls; ALA of both groups were similar. The blood lead level of traffic policemen was not related to age, duration of employment or Hb. Although the observed blood lead level of Cairo traffic policemen (29.2 +/- 7.5 microns dl-1) may be considered acceptable for their occupation, it indicates a potential risk from traffic-exhaust-induced air pollution for other groups of the Cairo population such as children and pregnant women.
对开罗市126名交警和50名办公室工作的警察组成的对照组测定了血铅水平、血红蛋白浓度（Hb）和尿δ-氨基乙酰丙酸（ALA）。交警的平均血铅水平和Hb显著高于对照组；两组的ALA相似。交警的血铅水平与年龄、工作年限或Hb无关。尽管开罗交警观察到的血铅水平（29.2±7.5微克/分升）对其职业来说可能被认为是可接受的，但它表明开罗其他人群如儿童和孕妇存在交通尾气导致的空气污染带来的潜在风险。
