| Abstract | The purpose of this work is to better understand the complex behavior of certain important species that affect air quality in general, and haze formation in particular. With funding from LADCO and CENRAP we are monitoring ambient gasphase ammonia, sulfur dioxide and nitric acid, as well as ammonium, sulfate and nitrite in PM?2.5 filter samples collected at selected sites in the Midwest?one each in Iowa, Illinois, Missouri, Kansas, Oklahoma, Kentucky, Ohio and Michigan, and two in Minnesota. Two types of timer?operated field samplers are deployed in this project?the commercially available model 2300 from Ruprecht and Patashnick (R&P), and the ISWS custom?built system, which uses a cyclone (R&P uses an impactor), denuders and filter pack assemby from University Research Glassware (URG). Samples are collected on a rotating one?day?in?six schedule that coincides with other nationwide air monitoring programs. At the Bondville, IL site, ambient ammonia concentrations are also measured every 35 seconds by a Nitrolux?200 photoaccoustic monitor. Samples extracted from denuders and filters are analyzed in the National Atmospheric Deposition Program?s Central Analytical Laboratory using ion chromatography and flow injection analysis under strict quality control. Data from this project will facilitate computer simulations of the possible effects of emissions controls, and other scenarios of environmental interest. |
