“…Not only does the PM 2:5 concentration vary among stations and cities, but the elemental composition of PM 2:5 . Previous studies have demonstrated that underground depth (Vilcassim et al 2014;Figueroa-Lara et al 2019), station volume, age (Van Ryswyk et al 2017), and ventilation (Martins et al 2016) all affect aerosol loading. Therefore, these subway system-and station-dependent differences were not unexpected in the present study.…”

The goals of this study were to assess the air quality in subway systems in the northeastern United States and estimate the health risks for transit workers and commuters. METHODS: We report real-time and gravimetric PM 2:5 concentrations and particle composition from area samples collected in the subways of Philadelphia, Pennsylvania; Boston, Massachusetts; New York City, New York/New Jersey (NYC/NJ); and Washington, District of Columbia. A total of 71 stations across 12 transit lines were monitored during morning and evening rush hours. RESULTS: We observed variable and high PM 2:5 concentrations for on-train and on-platform measurements during morning (from 0600 hours to 1000 hours) and evening (from 1500 hours to 1900 hours) rush hour across cities.

“…The air quality of subway station is largely dependent to characteristics of location and space. Figueroa-Lara et al (2019) found that higher concentration of PM in deeper subway station. PM levels inside the trains and platform decreased with the passage in aboveground sections Carteni et al, 2015;Cheng et al, 2011).…”

In this study, we measured simultaneously particle matter (PM10 and PM2.5) mass and their heavy metal concentrations for three days at a Seoul subway station (outdoor, concourse, platform, and tunnel) to investigate airborne PM flows. The average PM10 concentration were 59 µg m-3 , 37 µg m-3 , 111 µg m-3 and 369 µg m-3 ; PM2.5 concentration were 43 µg m-3 , 28 µg m-3 , 58 µg m-3 and 132 µg m-3 in outdoor, concourse, platform and tunnel, respectively. Although PM temporal variations were highly correlated between adjacent sampling locations in subway station, PM2.5 temporal correlations were higher than PM10. The concentration of iron (Fe) was the highest among airborne trace metals in station sectors (concourse, platform, and tunnel). Using a simple mass balance model with Fe concentrations and ventilation rates, we calculated the origins of PMs in concourse and platform. 78% of PM10 and 62% of PM2.5 in platform were derived from the tunnel, whereas 84% of PM10 and 87% of PM2.5 in concourse from the filtered outdoor air. We further confirmed that the most effective way to reduce PM in platform to keep the highest peak under the national indoor air quality guideline is to reduce up to 80% PM input from tunnel source.

“…ALF has since been slightly modified compositionally to test a variety of materials such as stainless steels (Herting et al 2007), alloys (Hedberg et al 2010), and occupational dust (Witt et al 2014;Brown et al 2019;Figueroa-Lara et al 2019). A study on stainless steel alloys determined preferential leaching of Fe followed by Ni and Cr, primarily in the first hour of immersion in ALF (Herting et al 2008).…”
