Impacts of Subway System Modifications on Air Quality in Subway Platforms and Trains

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. Keywords: indoor microclimate, air quality monitoring, data acquisition systems, temperature-humidity index, Geographic Information System

Ambient Air Quality Standards

The Clean Air Act Amendments of 1970 provide the basis for a dramatic change in Federal air quality programs. The Act establishes new standards for motor vehicles and requires EPA to establish national ambient air quality standards, standards of performance for new stationary sources of pollution, and standards for stationary sources emitting hazardous substances. Further, it establishes procedures which allow states to set emission standards for existing sources in order to achieve national ambient air quality standards. The Act also permits the Administrator of EPA to register fuels and fuel additives and to regulate the use of motor vehicle fuels or fuel additives which pose a hazard to public health or welfare.National air quality standards for particulate matter have been established. Asbestos, mercury, and beryllium have been designated as hazardous air pollutants for which Federal emission standards have been proposed.
