National Performance Audit Program; ambient air audits of analytical proficiency, 1987
The report presents the results of the U.S. Environmental Protection Agency's 1987 National Ambient Air Audit Program by pollutant and by analytical method. Semiannual audits were conducted for CO, Pb, NO/sub 3/ and SO/sub 4/ (filter strips) and acid rain, and an annual audit was conducted for particulate sampler flow rate. Continuous SO/sub 2/ monitors were audited throughout the year such that no monitor was audited more than once. Approximately 45 laboratories participated in each semiannual acid rain audit and in each NO/sub 3/ and SO/sub 4/ audit and approximately 90 laboratories participated in each Pb audit. Five hundred and ninety-five CO monitors, 262 SO/sub 2/ monitors, and 1333 high volume flow samplers were also audited. The results for each 1987 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.
