交通环境污染对交通警健康影响的调查

The effect of traffic enviromental pollution on health status of traffic policemen

本文对123名交通警健康检查,以神经系统、呼吸系统和精神方面改变明显。听力测试经年龄修正后,以高频听力损失为主,未见语频听力损失,与同声级稳态噪声的高频听力损失对比有显著性差异。交通警碳氧血红蛋白均值为0.0233,明显高于对照组0.0147,P<0.01。本次调查结果表明,交通警的碳氧血红蛋白伍增高和出现一系列神经功能性变化及听力损失,系交通噪声、一氧化碳共同作用的结果。

A health survey on 123 traffic policemen was performed. The changes in nervous system, respiratory system and psychogenic system appeared to be obvious. Hearing loss, mainly in high frequencies without that in spoken frequencies were found after age correction. However, there was an obvious difference between the high frequency hearing loss in certain noise level of traffic noise and that in the same level of steady noise. Meanwhile, the average value of carboxyhemoglobin in traffic policemen was 0.0233, being obviously higher than that of control 0.0147, highly significant statistically (P<0.01). It demonstrated that the raise of the level of carboxyhemogiobin and the appearance of a series of functional changes in nervous system as well as hearing loss were probably due to the comb nating effect of the traffic noise and circumstantial carbon-monoxide.
