Investigation of Submicrometer Aerosols for Apportioning the Impacts of Airborne Particulate Matter at Deep Creek Lake: Final Report.

摘要

In August and early September of 1983, the Environmental Protection Agency (EPA) conducted an extensive receptor modeling study at and around the Deep Creek Lake area of northwestern Maryland. The overall purpose of the study was (1) to test sampling techniques, (2) develop receptor models (most notably the hybrid tracer receptor model), and (3) to assess the impact of both primary and secondary emissions from local and distant fossil-fuel combustion sources. The EPA operated dichotomous samplers, a rain collector, an SO2 analyzer and other instruments for a 40-day period on the grounds of the Garret Community College located at the northeast tip of the lake. In addition, meterological data were obtained daily from a variety of sources for computation of air mass back-trajectories. The Department of Energy (DOE) and the Electric Power Research Institute (EPRI) confunded helicopter and fixed-winged aircraft flights to provide a ''regional air mass signature'' and ''signatures'' for three coal- fired power plants (CFPP) with significant potential for impacting DCL. The plume of a pulp and paper mill was also sampled and particulate samples were collected in-stack at three of the power plants. Analytical results for these samples were to be used to test one or more receptor models. 24 refs., 18 figs., 15 tabs. (ERA citation 14:029361)
