The objective of this research project is to identify key particulate matter (PM) components and source types that are associated with respiratory and cardiovascular morbidity and to provide excess risk estimates for subpopulations that are characterized by age group, diagnoses, and subareas within New York City. This project takes advantage of the newly available rich chemical speciation data being collected in New York City and the hospital admission data for all ages from the Statewide Planning and Research Cooperative System. We also will examine the emergency room (ER) visits for asthma in the New York City hospitals (a collaboration with Robert Silverman at the Long Island Jewish Hospital and Lori Stevenson at the Mt. Sinai School of Medicine with no additional cost).

This is one of the projects funded by the New York University (NYU) PM Center. The progress for the other projects is reported separately (see reports for R827351C001 through R827351C013, R827351C015, and R827351C016).

Progress Summary:

Currently, there are three PM2.5 chemical speciation monitors in New York City: the New York Botanical Gardens (NYBG) in the Bronx; I.S. 52 in the Bronx; and Queens College (QC) in Queens. The data are available starting from 2000 for NYBG and from 2001 for I.S. 52 and QC. Available PM components to be analyzed are: (1) PM2.5 particulate mass; (2) anions and cations by ion chromatograph; (3) trace elements (about 20 key elements from sodium through lead on the periodic table) by energy dispersive x-ray fluorescence; and (4) total carbon, including organic, elemental, and carbonate carbon, by thermal optical analysis. In addition to the chemical speciation data, PM2.5 data from approximately 20 monitors in New York City also will be examined.

We conducted an analysis of PM2.5 speciation data from three monitors (a few miles apart) in New York City during 2001-2002 (Ito, et al., 2004; funded by a Science To Achieve Results grant from the U.S. Environmental Protection Agency) and found that t he strongest temporal correlations across the three monitors were found for the individual PM components that are related to secondary aerosols (e.g., S, NH4). Our source apportionment using absolute principal component analysis and positive matrix factorization identified four major source/pollution types—secondary (largely regional) aerosols, soil, traffic related, and residual oil burning/incineration—in each of the three monitors. We will analyze these source-apportioned PM2.5 mass concentrations for their associations with the morbidity outcomes. We conducted a preliminary analysis of the asthma emergency room (ER) visits data. We assumed that the conditions associated with asthma would vary across age, and therefore examined four age groups separately: 2-4, 5-11, 12-17, and 18-45. We first analyzed the citywide average PM2.5 data for 1999 and 2002. PM2.5 risk estimates were obtained for each of the four age groups using the Poisson Generalized Linear Model adjusting for weather, day of week, seasonal trends, the fall peaks, and seasonal recesses. The resulting relative risk estimates were fairly comparable across age groups: 1.20 (95% confidence interval [CI]: 1.11-1.30); 1.16 (95% CI: 1.07-1.26); 1.14 (95% CI: 1.03-1.27); and 1.12 (1.06-1.18), respectively. Currently, we are examining the role of source-apportioned PM2.5 in these PM-asthma ER visit associations.
