Abstract
|
|
|
In this study, Particulate carbon were determined from 1990 to 1995. The annual variation were investigated. The sampling was carried out using high volume air sampler.
Average concentrations of EC and OC during the yellow sand event were 25.70㎍/㎥ and 13.91㎍/㎥, respectively, 22.10㎍/㎥ and 10.33㎍/㎥ during the non-yellow sand event. TC concentration of TSP were 10.7% during the yellow sand event and 20.6% during the non-yellow sand event. Average concentration rate of EC and OC of TC were 64.9% and 35.1%, respectively during the yellow sand event, 67.6% and 32.4% during the non-yellow sand event.
