Monitoring the Indoor Air Quality and Microclimate for Improving Passenger Health and Comfort Level in Bucharest Subway Platforms

Abstract

This paper presents the results of the air quality by the content of CO2, CO, PM2.5, PM10 and the microclimate (temperature and relative humidity) monitoring campaign, in Bucharest underground transport network. The monitoring was performed using both manual and automatic data acquisition systems. All the acquired data were stored in a specific database system used for fast reporting and alarming. GIS software was used to precisely locate the exterior air intakes for selected stations in order to know the quality of the exterior air circulated through them and for finding the best position for new ones. The research was conducted on different station platforms, belonging to the same line, in the Bucharest subway system throughout a year (2015) in order to improve air quality and comfort level of subway stations. The obtained results will serve as basis for improving the air quality and comfort level in the new long subway lines designed and built now in Bucharest.
