Source Sampling Fine Particulate Matter: Wood-Fired Industrial Boiler.

摘要

Fine particulate matter of aerodynamic diameter 2.5 m or less (PM-2.5) has been implicated in adverse health effects, and a National Ambient Air Quality Standard for PM-2.5 has been promulgated (July 1997) by the U. S. Environmental Protection Agency. A national network of ambient monitoring stations has been established to assist states in determining areas which do not meet the ambient standard for PM-2.5. For such areas, it is important to determine the major sources of the PM-2.5 so states can devise and institute a control strategy to attain the ambient concentrations set by the standard. One of the tools often used by states in apportioning ambient PM-2.5 to the sources is a source-receptor model. Such a model requires a knowledge of the PM-2.5 chemical composition emitted from each of the major sources contributing to the ambient PM-2.5 as well as the chemical composition of the PM-2.5 collected at the receptor (ambient monitoring) sites. This report provides such a profile for a wood-fired industrial boiler equipped with a multistage electrostatic precipitator control device. Along with the PM-2.5 emission profile, data are also provided for gas-phase emissions of several organic compounds. Data are provided in a format suitable for inclusion in the EPA source profile database, SPECIATE.
