摘要
目的 探讨道路收费站作业环境污染程度。方法 采用部颁《劳动卫生工作规范》中的方法对收费站十条车道收费亭的环境因素进行监测与分析。结果 收费站十条车道收费亭内外空气中的ＣＯ、ＳＯ２ 、ＮＯ２ 和粉尘浓度均严重超过标准；交通噪声亭内７８ ～８７ ｄＢ（Ａ） ，亭外８８ ～９８ｄＢ（Ａ） ，等效声级亭内８０Ｌｅｑ ｄＢ（Ａ） ，亭外９０ Ｌｅｑ ｄＢ（Ａ） ，各测点均超过标准７０ Ｌｅｑ ｄＢ（Ａ） ，车流量每１０ 分钟５１０ ～７５０ 辆。夏季亭外站台上温度高达３６ ～３７ ℃，符合Ⅱ级高温作业。结论 道路收费站作业环境因素严重超标，必须加强个人防护和职业健康监护。
Objective In order to explore the status of environmental contamination in traffic toll gate.Methods In accordance with the methods of The Criterion of Labor Health Works, the working environmental factors of a traffic toll gate with ten passages was monitored and analyzed.Results The air concentration of CO, SO 2, NO 2 and dust due to motor vehicles severely exceeded the national standards. The road traffic noise levels were 80～90 Leq dB(A). In all monitored sites the noise appeared to be much higher than the national standard 70 Leq dB(A). The automobile pass was counted to be 521～750 vehicles/10 min. The temperature were 36～37℃ in working site which corresponded to second class of high temperature working. Conclusion The working environmental factors severely exceeded the national standards in a traffic toll gate. The personal protection and occupational health surveillance should be recommended.
