bibo:abstract
  • The purpose of this study is to develop an ozone passive sampler and to evaluate its performance. p-Acetamidophenol using as the reagent for ozone reacts specifically with the ambient ozone to produce a fluorescence material (p-acetamidophenol dimer). The volume of absorbent solution and the extraction time determined as suitable conditions for measuring ozone were 100 μL and 60 min, respectively. The changes of fluorescence were observed with incresing the storage period of passive samplers in ambient air, but the cool storage in a refrigerator did not remarkably influence the increase of fluorescence. The measurement for the precision of the passive sampling was carried out with duplicate measurement of passive samplers. The intra-class correlation coefficients of passive samplers using dry and wet filters were 0.992 and 0.962, respectively. The results from field validation tests indicated practical agreement (dry filter : r=0.963, wet filter : r=0.995) between the passive sampler and an UV photometric O₃ analyzer. The limit of quantification of ozone passive samplers with sampling time of 8 hr (wet filter) and 24 hr (dry filter) were 8.0 ppb and 2.7 ppb, respectively. (rdf:langString) (en)
