人防工程改建工作车间夏季环境卫生状况调查与评价

Investigation and Evaluation on the Hygienic Status of Workshop Rebuilt from Civil Air Defense Engineering in Summer

目的测定由人防工程改建的工作车间内夏季的微小气候、空气中总悬浮颗粒物(TSP)浓度与细菌总数,为改善人防工程内环境质量提供科学依据。方法在一天中的不同时段,在人防工程外的对照采样点和工程内的工作车间内采样,测定各项空气质量参数,并且对2个地点的空气状况进行比较。结果在各个采样时段,人防工程内作业环境中的温度和风速均显著低于外界对照采样点,而相对湿度则显著高于外界对照采样点。空气中的TSP浓度和细菌总数也显著高于对照采样点。结论需要采取有效的措施改善人防工程中的空气质量状况。

Objective To determine the microclimate, total suspended particulate （TSP） and total bacterial count in the workshop rebuilt from civil air defense engineering in summer and to provide scientific evidence for improving the environmental quality of civil air defense engineering. Methods In three periods of one day, samples were collected at the corresponding points of workshop and the control site.Parameters about air quality were determined, and comparison was made between the two sites. Results The temperature and wind velocity in workshop were significantly lower than those of the outside, but the relative humidity, TSP concentration and the total number of bacteria were significantly higher. Conclusion It＇ s necessary to take effective measures to improve the air quality of the civil air defense engineering.
