Cross-Appalachian Tracer Experiment (CAPTEX '83) quality assurance of surface samples

Seven separate releases of perfluoromonomethylcyclohexane tracer from either Dayton, Ohio or Sudbury, Ontario determined atmospheric transport and dispersion across the Appalachian Mountains to the northeastern United States and southeastern Canada. Surface samplers were emplaced in an array along the expected tracer plume trajectory. The EML quality assurance procedures for the preparation of the samplers as well as estimates of the precision and accuracy of sampling and gas chromatographic analysis are discussed. 6 refs., 4 figs., 6 tabs.
