职工住室空气质量的优劣,直接影响着居住者的健康.许多资料报道,空气离子浓度可作为空气质量的评价指标.为了评价铁路基层职工住室空气清洁程度,于1995年夏、冬两季检测了三处职工住室的空气离子浓度,结果报告如下:1 调查对象与方法1.1在山东日照、济南,江苏南京三城市郊区铁路施工队职工住室内,各选择一间有代表性的住室为监测点,同时设室外对照点.分别于早(6:00～7:00)、中(12:00～13:00)、晚(18:00～19:00),采用CN—FI型空气离子浓度测试仪,测量正、负离子浓度,每次连续读取12个数值,取均值,同时记录气温、气湿、气流,每个调查点夏、冬两季各连续检测5天.
The merits of the air quality of workers in the housing directly affect the health of occupants.Many sources reported air ion concentration can be used as an indicator of air quality.In order to evaluate the air cleanliness of workers in railway grassroots units in the summer of 1995, Quarter of the three test workers in the air concentration of residential air rooms, the results reported as follows: 1 survey of objects and methods 1.1 in Shandong Rizhao, Jinan, Jiangsu Nanjing three suburban railway construction team workers living room, choose a representative of the live Room as the monitoring point, at the same time, set up outdoor control points respectively in the early (6: 00 ~ 7: 00), mid (12: 00 ~ 13: 00), late (18: 00 ~ 19: 00) Type air ion concentration tester, measuring the concentration of positive and negative ions, each reading 12 consecutive values, taking the mean, while recording temperature, humidity, air flow, each survey point summer and winter, the two consecutive testing five days.
