摘要
目的了解人员进驻坑道的环境卫生质量及危害因素。方法选择某指挥坑道内人员生活区,现场监测人员进驻前后密闭坑道内微小气候、氧含量、化学因素污染、物理因素污染和细菌总数的变化。结果人员进驻前后,密闭坑道内气压、风速、氧含量、CO、SO_2、H_2S、NO_2、NH_3和细菌总数等指标均符合《二炮阵地人员生存生活条件要求》,人员进驻后坑道内空气中总悬浮颗粒物(TSP)浓度明显升高,最高值为0.35 mg/m^3,平均值为0.26 mg/m^3,噪声最高值为80.6 dB,TSP和噪声均超过标准限值要求。结论人员在坑道内工作和生活时,影响坑道环境卫生质量的主要危害因素是TSP和噪声。
[Objective] To understand the environmental sanitary quality and hazard factors of tunnel after personnel entrance. [ Methods ] The staff living area of a command tunnel was select as the investigation site. The changes of microclimate, oxygen content, chemical pollution, physical pollution and total bacterial count before and after personnel entrance were monitored. [Results] Before and after personnel entrance, the air pressure, wind speed, oxygen content, CO, SO2, H2S, NO2, NH3 and total bacterial count met the requirements of Survival condition of battle stations personnel in the Second Artillery. After personnel entrance, the concentration of total suspended particle （TSP） in air increased significantly, with the maximum value of 0.35 mg/m^3 and the average value of 0.26 mg/m^3, while the maximum value of noise was 80.6 dB, and both of TSP concentration and noise intensity exceeded the limits. [ Conclusion] The main harmful factors affecting the environmental health quality of tunnel are TSP and noise when personnel work and live in tunnel.
