Institution: NYU School of Medicine
EPA Project Officer: Stacey Katz/Gail Robarge,
Project Period: June 1, 1999 through May 31, 2005 (Extended to May 31, 2006)
RFA: Airborne Particulate Matter (PM) Centers (1999)
Research Category: Particulate Matter

Description:

Objective:

The objective of this research project is to examine the surface chemistry of fine particulate matter (PM2.5) collected from concentrated diesel exhaust at roadside urban and rural background locations. In this project, x-ray photon spectroscopy and time-of-flight secondary ion mass spectrometry are used to determine the surface chemistry. Scanning electron microscopy is used to characterize the particles morphologically. The effects of PM surface chemistry and morphology on determining the interactions with human chronic obstructive pulmonary disease (COPD) and normal lavage samples (and components of normal human lavage) then will be quantified, using the same techniques. In addition, enzyme linked immunosorbent assays for specific proteins and a surfactant quantification method will be used to determine lavage component concentrations before and after the introduction of PM.
