United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park, NC 27711 Research and Development EPA/600/SR-93/057 May 1993 v/EPA Project Summary Analysis of Atmosphere Deposition Samples From Easton, PA David Natschke An industrial area near Easton, PA, has been troubled for a number of years with the accumulation of tenacious at- mospheric deposits on exposed sur- faces such as automobiles and houses. The State of Pennsylvania requested assistance from the U.S. Environmen- tal Protection Agency, under the Con- trol Technology Center, for the analy- sis of these deposits. The Pennsylva- nia Department of Environmental Re- sources collected samples at two sites in the area. At the two sites, samples were collected on organic membrane material for elemental analysis by X- ray fluorescence and on glass plates for inorganic phase analysis by X-ray diffraction. The glass plates were sub- jected to various methods of analysis to determine the organic species present. This Project Summary was developed by EPA's Air and Energy Engineering Research Laboratory, Research Tri- angle Park, NC, to announce key find- ings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back).
