Institution:Oregon Graduate Institute of Science & Technology EPA Project Officer: Hahn, Intaek Project Period: October 1, 1996 through September 30, 1999 Project Amount: $466,448 RFA: Exploratory Research - Air Engineering (1996)RFA Text | Recipients Lists Research Category:Air Quality and Air Toxics ,Land and Waste Management ,Air ,Engineering and Environmental Chemistry Description: EPA (1994b) has reaffirmed the toxicities of certain chlorinateddibenzodioxins (CDDs) and chlorinated dibenzofurans (CDFs), and has concludedthat some in the population may already be experiencing associated healthproblems. Since 85% of the environmental load of these compounds is released tothe atmosphere by incinerators and other sources, human exposure is due mainlyto contamination of foods by atmospheric deposition from the gas (G) andparticulate (P) phases. Since gases and particles deposit to surfaces atdifferent rates, understanding how CDDs and CDFs partition between the G and Pphases in the ambient atmosphere is very important (EPA, 1994b). This processalso affects deposition to "Great Waters". This project will provide a comprehensive study of how these toxic anddifficult-to-work with compounds partition between the G and P phases in theatmosphere using three research components: "controlled field experiments" (CFEs), a new type of sampling experimentwhich will be held at constant T and RH, and conducted in several large cities (Portland, Denver, Chicago) and one rural location (Tennessee) over a range of Tand RH conditions; conventional high-volume filter/sorbent air sampling along with CFEs; and laboratory sorption experiments carried out using model atmosphericmaterials (quartz, graphitic carbon, ammonium sulfate, flyash, dieselparticulate material, and NIST standard UPM) to provide theoretical guidance andgeneral interpretive support.In addition, the importance ofadsorption and absorption as G/P partitioning mechanisms will be determined.
