Laboratory and field experiments were performed to evaluate integrative measurement methods for atmospheric nitrates, sulfate and sulfur dioxide. Denuder tubes and several filter media were tested under laboratory and field conditions. Effects of sampling variables such as temperature and relative humidity, flow rates, concentration, loading capacity and artifacts due to NO, NO/sub 2/ and SO/sub 2/ were also evaluated. The integrative filter sampling method and the ion chromatographic analytical procedure gave a measurement precision (relative standard deviation) of +/- 11.5% for particulate NO/sub 3//sup -/ on Teflon and +/- 15.6% for gaseous HNO/sub 3/ on nylon; for both these constituents, the detection limit was about 0.1 ..mu..g m/sup -3/.
