摘　　要：重在市区８个交通主干道ＣＯ、ＮＯｘ和ＳＯ２浓度超过ＧＢ３０９５一８４《大气环境质量标准》三级规定。超标最高为６．８７倍。交通噪声范围６０～９０ｄＢ（Ａ）。全部测量点超过标准７０ＬｅｑｄＢ（Ａ）。车流量为２５２～６３１辆／１０ｍｉｍ。车流量与Ｌｅｑ等效声级，Ｌｉ０，Ｌ５０和Ｌ９０均有显著性相关，尤以Ｌ５０最显著。夏季作业环境气温３６～３９℃，太阳辐射热为１．２～１，５ｃａＬ／ｃｍ２·ｍｉｎ。符合高温Ⅱ级作业。he hazard factors from working sites of the traffic policemen were investigated on the eighthighway in Chong-qing. The SO2, NOand CO concentrations preducted by motor vehicles exceed-ed the ntional standard 6. 87times.The road traffic noise levels were 60-90dB(A). The epujvalentsound pressure levels were 70. 5-75. 7LeqdB(A).In all of highway the noise higehr than that ofnational standard,70 LeqdB(A) . The automobil passed counts were 252-631 vehicles/ 10 min.The conts correlated with Leq, statistic sound L10, L50 and L90.The correlative coefficient of L 50 was 0. 797 (P<0. 01).The temperrature were 36-39 ℃ in owrking sites. The sun raidiant heatwere 1. 2-1. 5 cal/cm2 min ,which corresponded to third class of the high temperature working.
