CHEN, F., P. PHOUSONGPHOUANG, R. W. BALDAUF, R. W. WIENER, F. DIMMICK, AND M. WHEELER. PARTICULATE MATTER CONCENTRATIONS MEASURED IN A RESIDENTIAL NEIGHBORHOOD IN BROOKLYN, NEW YORK CITY DURING THE TRAFFIC-RELATED EXPOSURE STUDY (T-REX). Presented at AAAR 2006 , St Paul, MN, September 11 - 15, 2006.
Impact/Purpose:
The main research question guiding this task is "how do mobile source emissions impact public health and the environment." The main objectives of this task include:
(1) Identify spatial and temporal variability in pollutant concentrations near major mobile source emission locations such as urban roadways and non-road activities.
(2) Characterize real-world emissions from on- and non-road mobile sources for use in identifying hazardous components and developing and improving mobile source emissions and human exposure models.
(3) Develop mobile source emission profiles and markers for use in human exposure and air quality receptor models.
(4) Determine the impact of emerging technologies (fuels and engine systems) on emissions and exposures to toxic pollutants.
(5) Develop and improve analytical methods that measure emissions from mobile sources.
Description:
PM10, PM10-2.5, and PM2.5 concentrations has been measured daily in the Sunset Park neighborhood of Brooklyn, NY from April 21 to May 17, 2005. Results showed the average concentrations of PM fractions were higher when measured closet to the major roadway.
