The report documents the discussions and results of the U.S. Environmental Protection Agency's (EPA's) Acid Aerosol Measurement Method Intercomparison Workshop, held April 10-11, 1991 in Research Triangle Park, NC. The workshop was designed to achieve two objectives: (1) to report on recent method intercomparisons for strong acid measurements, and (2) to report on recent acid aerosol characterization studies and to discuss plans for future urban studies. The EPA investigators reported on two laboratory intercomparisons, made by three participants, sampling relatively simple mixtures or pure acidic compounds; the outcome of an outdoor smog chamber intercomparison was also reported on. The investigators concluded that hydrogen ion could be measured with a precision of 10-25%. Ten additional presentations related to these intercomparisons were also given. Three presentations on acid aerosol characterization studies were also given. These studies concluded that sulfate cannot be used to predict acidity. Future characterization studies implemented by EPA were also discussed.
