【摘要】 目的了解半封闭式客运交通枢纽空气污染对人群健康的影响。方法在半封闭式客运交通枢纽内外选取不同监测点,在不同时间里对一氧化碳、非甲烷总烃、氮氧化合物、二氧化硫和可吸入颗粒物的浓度进行监测,并选择部分工作人员和乘客进行问卷调查。结果在枢纽内停留时间越长,其呼吸道、感官及神经系统症状越明显,主要不适表现在感觉枢纽内有刺激性气味和眼部刺激。结论目前半封闭客运交通枢纽内空气污染状况不容忽视,建议相关部门尽早制定标准保护人体健康。更多还原

【Abstract】 Objectives To understand the health effect of air pollution in semi-enclosed large-scale integrated transportation hubs.Methods The concentration of carbon monoxide(CO),non-methane hydrocarbon(NMHC),nitrogen oxide(NOx),sulfur dioxide(SO2) and particulate matter(PM10) was detected at different monitoring sites inside and outside of the hub.A questionnaire survey was conducted among staffs and passengers in the hubs.Results The longer the stay in the hub the more obvious symptoms of respiratory,sensory and nervous system;the main discomfort perception was pungent odor and eye irritation.Conclusions The current situation of air pollution in the semi-enclosed large-scale integrated transportation hubs could not be ignored.Relevant standards should be developed as early as possible to protect human health.更多还原
