以上海市四个区的交通警184人,打浦路隧道工58人为接触组,植物园工人106人为对照组,研究了汽车排气对其健康的影响。发现隧道工、交通警的主诉症状、客观体征和铅接触的生化指标方面与对照组比较,有显著差别(P<0.05及0.01)。不论吸烟与否,隧道工血中HbCO含量的最高值都是在值勤后,系因值勤时吸入过量的CO所致。说明汽车排气对交通警及隧道工人的健康已产生一定的影响。 Traffic police in four districts of Shanghai Municipality, 184 traffic police, Dapu Road tunnel workers 58 for the contact group, 106 botanical garden workers as a control group to study the impact of vehicle exhaust on their health. There were significant differences (P <0.05 and 0.01) between the complainant symptoms of tunnel workers and traffic police, the objective signs and the biochemical indexes of lead exposure compared with the control group. Regardless of smoking or not, the highest HbCO levels in tunnel workers’ blood are all caused by inhaling excessive CO when on duty. This shows that car exhaust has a certain impact on traffic police and tunnel workers’ health.
