National Performance Audit Program: ambient air audits of analytical proficiency - 1984
The report presents the results of the U.S. Environmental Protection Agency's 1984 National Audit Program by pollutant and by analytical method. Semiannual audits were conducted for Pb, NO/sub 3/ and SO4 (filter strips) and one audit was 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. Twenty laboratories participated in the SO/sub 2/ bubbler audit, and 21 in the NO/sub 2/ audit, a 20% decrease from 1983. 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 thirty CO monitors, 221 SO/sub 2/ monitors and 1402 high-volume flow samplers were also audited. The results for each 1984 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.
