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.
