University at Albany 2000-2004
Program Overview

PM2.5 Technology Assessment and Characterization Study-New York is one of several U.S. EPA "Supersites" intended to provide enhanced measurement data on chemical and physical composition PM and its associated precursors. The science team lead by the University at Albany (PI: Kenneth Demerjian, ASRC/DEAS), includes investigators from ten participating institutions. The science team will collect, analysis and interpret these data to 1) characterize the PM2.5/Co-pollutant complex and its related sources and sinks; 2) support health effects and exposure research; 3) evaluate new measurement technologies and establish their potential for routine monitoring; and establish and demonstrate the use of these data analyses to track mitigation progress and support an accountable air quality management process.

PM2.5, like O3, has a regional component that must be characterized to determine its source and its potential role in the development of mitigation strategies for non-attainment areas. The revised ozone and newly promulgated PM2.5 national ambient air quality standards have placed additional demands on our understanding of the interdependencies of these pollutants and their precursors. This additional knowledge is necessary to implement effective mitigation strategies to achieve these standards. The impact of ineffective, costly emission controls on the economy of New York State and the consequences of environmental benefits lost, present a strong case for the establishment of a EPA PM2.5 "Supersite" in New York State and is reflected in the substantial cost sharing commitment made by the NYS Department of Environmental Conservation (NYSDEC) and NYS Energy Research and Development Authority (NYSERDA) in support of this program.
