National Performance Audit Program -- ambient air audits of analytical proficiency - 1985
The report presents the results of the U.S. Environmental Protection Agency's 1985 National Audit Program by pollutant and by analytical method. Semiannual audits were conducted for Pb, NO/sub 3/ and SO/sub 4/ (filter strips) and acid rain, and annual audits were conducted for SO/sub 2/ (bubbler), NO/sub 2/ (bubbler), CO, and high-volume flow rate. Continuous SO/sub 2/ monitors were audited throughout the year, such that no monitor was audited more than once. Approximately 30 laboratories participated in each semiannual acid rain audit. Twelve laboratories participated in the SO/sub 2/ bubbler audit, and 18 in the NO/sub 2/. Approximately 55 laboratories participated in each NO/sub 3/ and SO/sub 4/ audit and approximately 100 laboratories in each Pb audit. Three hundred and twenty-five CO monitors, 257 SO/sub 2/ monitors and 1336 high-volume flow samplers were also audited. The results for each 1985 audit are presented in tabular form for each concentration level. The overall performance for all participants for each audit conducted since the beginning of the program is also illustrated in a series of figures.
