【摘要】 目的探讨教室空气总悬浮颗粒物(TSP)污染的健康影响。方法在某大学每个上课的教室讲台旁以100L/min流量进行连续6h空气采样(n=270),并以办公楼为对照点(n=10)。对全校教师进行呼吸系统疾病调查。结果该大学教室空气TSP浓度为0.10～0.88mg/m3,均值约0.38mg/m3而该校办公室仅为0.09mg/m3,该市大气TSP均值仅0.194mg/m3,约29%教室空气TSP浓度高于大气质量三级标准,教师呼吸系统疾病患病率随教龄增长而上升,该校教师急、慢性咽炎、急性气管-支气管炎和慢性支气管炎患病率分别为23.3%、73.9%、4.0%和17.4%,而行政管理人员仅分别为4%、2.8%、3.2%和7.1%。结论教室空气TSP污染对教师呼吸系统有危害。更多还原

【Abstract】 Objective To explore the effects of TSP in classroom air on teachershealth.Methods Air sampling was car-ried out nearby the platform in each in use-classroom at flow of100L/min continuously for6h(n=270)and in office building as controls(n=10)in a university.An investigation on the prevalence of respiratory diseases was performed also.Results The concentration s of TSP were0.10-0.88mg /m 3 in classroom air with a average level of0.38mg /m 3 ,and only0.09mg /m 3 in office air of the university,and0.194mg /m 3 in the ambient air respectively.The TSP concentrations in the classromms exceeded the National Standard of Ambient Air Quality GradeⅢ.The prevalence rates of respiratory diseases including acute and chronic phyryngitis,acute tracheobronchitis and chronic bronchitis were23.3%,73.9%,4.0%and17.4%for teachers,only4%,2.8%,3.2%and7.1%for administrative staff respectively.Con clusion The classroom air pollution by TSP had adverse effects on teachershealth in classrooms.更多还原
