RAPS Quality Assurance audits were conducted under this Task Order in continuation of the audit program previously conducted under Task Order No. 58. Quantitative field audits were conducted of the Regional Air Monitoring System (RAMS) Air Monitoring Stations, Local Air Monitoring Stations (State of Illinois, St. Louis City, and St. Louis County), RAPS helicopters and various measurement systems employed in the RAPS intensive studies. Audit results are reported for systems measuring NO, NOx, O3, SO2, total sulfur, total hydrocarbons, CH4 and CO. An investigation was conducted on the effect of Teflon particulate filters on NO, NO2, O3, and SO2 concentrations in sampled air. Measured sample losses are reported for synthetic pollutant - air mixtures sampled through new and used filters under both dry and humid conditions. The investigation also revealed effects of humidity on the response of analyzers to the various pollutants. The accuracy of SO2 calibration mixtures prepared with the commercial dynamic calibration system employed in the audits was investigated. As a result of this investigation and experience gained during the audits, the calibration system was modified to improve performance under field conditions.
