摘要
目的了解广州地铁二号线开通前卫生状况并与一号线开通前进行比较。方法对广州地铁一、二号线开通前进行卫生监测,并对监测结果进行分析比较。结果地铁二号线运营前卫生环境较好,但一氧化碳、二氧化碳、甲醛及可吸人颗粒物易受地面环境影响。二号线的卫生状况比一号线有所改善,安装屏蔽门对氮氧化物、二氧化硫及微生物起到了阻隔的作用。结论广州地铁二号线开通前本底卫生环境优于广州地铁一号线。
Objective To analyze the sanitation status of Guangzhou metro 2nd line before operation, and compare it with Guangzhou metro 1st line. Methods Baseline study was performed in Guangzhou metro 1st line and 2nd line before operation. The results were analyzed and compared. Results The sanitation status of 2nd line was better than that of the 1st line.The CO, CO2, IP, and HCHO levels might be influenced by the aground environment. The improved sanitation status of 2nd line was the result of blocking NOX, SO2 and microbe with screen doors. Conclusion The background sanitation status of Guangzhou metro 2nd line before operation was better than that of the 1st line.
