In order to quantify mercury flux from nonpoint sources, methodologies used to measure flux must be critically assessed and those processes most critical for controlling flux need to be characterized. This report discusses the results of the Nevada Mercury Emissions Project (NvMEP). During September 1--5, 1997, nine teams of researchers from the US, Canada, Sweden and Germany met in Reno, Nevada to: intercompare mercury flux measurements obtained in situ using field chambers and micrometeorological methods from a naturally mercury-enriched terrestrial landscape; and discuss the application of local flux measurements to the development of regional and global atmospheric mercury budgets. During the field intercomparison, four micrometeorological methods and seven field chambers were used to measure mercury flux simultaneously from a {approximately} 500 m{sup 2} area at the Steamboat Springs Geothermal area, nevada. In addition, mercury flux was measured from soils collected from the field chamber sampling sites using a laboratory gas exchange chamber. This report describes the methods applied for the measurement of mercury flux, addresses their limitations, and intercompares the mercury flux data obtained.
