Residential Wood Combustion Study. Task 1. Ambient Air Quality Impact Analysis

摘要

The ambient air quality impact of Residential Wood Combustion (RWC) emissions in eight Pacific Northwest cities was studied during the 1980-81 space heating season. Seventy-seven worst case fine particle ambient samples collected in Seattle, Spokane, Yakima, Tacoma and Longview, Washington; Boise, Idaho; Portland and Medford, Oregon were selected and analyzed for Polynuclear Aromatic Hydrocarbon compounds, 35 trace elements and carbon. The impact of RWC and other sources was determined by Chemical Mass Balance (CMB) calculation and validated against independent carbon-14 measurement. This document describes the project design, methodology and results of the RWC impact monitoring program. The findings of this task form the basis for projections of future RWC impacts discussed under task 2A (PB84-170596) of this series. They also provide the first comprehensive survey of RWC impacts within Pacific Northwest communities during a period likely to be typical of maximum RWC emissions. Appendices from this task are contained in Report PB84-170588.
