Two methods for the determination of gaseous hydrogen peroxide in ambient air were tested during the Carbon Species Methods Comparison Study conducted at Glendora, CA, August 12-20, 1986. Air was sampled by the BNL dual impinger/diffusion scrubber apparatus after ambient ozone removal by addition of NO. Sampling was done during daylight hours (∼ 0800-2000 hours) from a sampling line shared with the National Center for Atmospheric Research (NCAR) and Texas Tech University (TTU) groups. Impinger data were formally compared with results from other methods; they showed afternoon maxima which were generally < 1 ppbv for the first 5 days, and > 1 ppbv the last 4 days of the study, respectively. Data from the diffusion scrubber agreed well with the impinger data if the former are corrected for an ∼ 40% aqueous phase loss of collected H2O2. Error sources for impinger and scrubber data resulting from potential interferences and loss mechanisms are discussed. |
