Source Characterization for Receptor Model Source Apportionment of Acid Rain Precursors. Final Report

摘要

The objective of this research was to develop and apply specialized sampling and analysis techniques to establish chemical and physical feature patterns of acid rain precursor sources for use with receptor model source apportionment methods. This objective was accomplished by determining the optimum particle size range for source characterization, modifying NEA's current size-segregating dilution sampler to simultaneously collect particles and measure SO sub 2 in the dilution chamber, and evaluate the modified sampler. Early in the program, emphasis was shifted to the collection of source samples representative of material emitted from coal fired power plants west of an ambient sampling site at Deep Creek, West Virginia.
