某部地下工事环境卫生学本底调查分析

Environmental Hygiene Background of Underground Bunkers

目的了解地下工事的环境卫生状况及危害因素。方法选择地下工事内人员生活区,对微小气候、化学因素、物理因素进行现场监测和水源水质调查。结果地下工事温度合格率98.5%,湿度合格率92.6%,甲醛合格率70%,噪声合格率88.9%,氡合格率81.9%,PM10合格率98.5%,照度合格率47.6%;水质总体合格率64.5%,风速、CO、CO_2、NH_3、NO_2、H_2S、SO_2、苯、甲苯、二甲苯、TVOC无超标。结论西南某部地下工事环境卫生本底主要危害因素是温度、相对湿度、氡及子体和甲醛,对进驻官兵健康有较大影响。

Objective To find out about the environmental hygiene and hazards in underground facilities. Methods The living quarters of the staff in underground fortifications were chosen for surveillance of the microclimate, chemical factors, and physical factors and for investigation of water quality. Results The qualified rate in underground bunkers was 98.5% for tempera- ture, 92.6% for humidity, 70% for formaldehyde, 88.9% for noise, 81.9% for radon, 98.5% for PM10, 47.6% for intensity of illumination and 64. 5% for overall water quality. Wind speed, NH3 , NO2, CO, CO2, H2S, SO2, benzene, toluene, xylene andTVOC were all up to standard. Conclusion The major hazards to environmental health in some of the underground bunkers in Southwest China are temperature, relative humidity, formaldehyde and radon, which have great impact on the health of the staff.
