- Abstract
- The objective of this study was to quantitatively estimate PM-10 source contribution in Gumi City, Korea.Ambient PM-10 samples were collected by a high volume air sampler, which operated for 84 different days with a24-h sampling basis, from June 14, 2001 though May 19, 2003. The ter samples were analyzed for determining13 inorganic elements, 3 anions, and a total carbon. The study has intensively applied a receptor model, the PMF(Positive Matrix Factorization) model.The results from PMF modeling indicated that a total of seven sources were independently identid and eachsource was contributed to the ambient Gumi City from secondary sulfate(34%), motor vehicle(26%), soil relation(5%), ld burning(3%), industrial relation(3%), secondary nitrate(22%), and incinration(7%) in terms of PM-10mass, respectively.
