Research Category: Targeted Research
Objective:
The overall objective of this research project, conducted by the Center for Air Toxic Metals (CATMSM), is to address air toxic trace element emissions that have become a matter of worldwide concern, as well as a regulatory issue in the United States. The goal of CATMSM is to develop key information on air toxic metal compounds to support the development and implementation of pollution prevention and control strategies that will effectively reduce air toxic metal emissions and releases to the environment.
The specific objective of this research project is to advance research in nickel speciation of residual oil ash.
Progress Summary:
Nickel, Chromium, and Arsenic Speciation of Ambient Particulate Matter (PM) in the Vicinity of an Oil-Fired Utility Boiler. Ambient particulate matter (PM), PM10, and PM2.5 were continuously sampled during August 26-31, 2002, from an urban State Monitoring Station and a Local Air Monitoring Station site in the vicinity of two oil- and gas-burning power plants. Urban PM, PM10, and PM2.5 samples were analyzed using x-ray absorption fine structure spectroscopy (XAFS) during October 18-22, 2002, at the National Synchrotron Light Source at Brookhaven National Laboratory, NY. XAFS is being used to directly determine the speciation of As, Cr, and Ni in ambient PM, PM10, and PM2.5 samples. Knowledge of the relationship between oil- and gas-burning power system emissions and ambient air quality will ultimately result in a more realistic inhalation-based risk assessment. Such an assessment is necessary for the U.S. Environmental Protection Agency to properly address public health risks and regulatory decisions.
