【 摘 要 】

Advanced Technology Systems, Inc. (ATS), with Desert Research Institute (DRI) and Ohio University as subcontractors, was contracted by the NETL in September 1998 to manage the Upper Ohio River Valley Project (UORVP), which included the establishment and operation of four ambient air monitoring sites located in the Upper Ohio River Valley (UORV). Two urban and two rural monitoring sites were included in the UORVP. The four sites selected for the UOVRP were collocated at existing local and/or state air quality monitoring stations. The goal of the UORVP was to characterize the nature and composition of PM{sub 2.5} and its precursor gases. In the process, the objectives of the UORVP were to examine the ambient air concentrations of PM{sub 2.5} as compared with the promulgated PM{sub 2.5} standards, the geographical, seasonal and temporal variations of ambient air concentrations of PM{sub 2.5}, the primary chemical constituents of PM{sub 2.5}, and the correlations between ambient air concentrations of PM{sub 2.5} and its precursor gases, other gaseous pollutants and meteorological parameters. A variety of meteorological and pollutant measurement devices, including several different PM{sub 2.5} samplers that provided either real-time or integrated concentration data, were deployed at the monitoring sites. The frequency of integrated sampling varied throughout the UORVP study period and was as follows: ''Intensive'' sampling periods were defined as periods in which samples were collected on a relatively frequent basis (ranged from 6-hour integrated samples collected round-the-clock to one 24-hour integrated sample collected every third day). ''Background'' sampling periods were defined as periods in which 24-hour integrated samples were collected every third or sixth day.
