We determined the concentrations of the odorants by instrumental
analysis and resident monitoring records of direct olfactory
observations. The highest odor strength was identified at the A-4
site at which product food and feed production facilities were
located. The concentrations of RSCs (especially H2S) were significantly
higher than the other odorous compounds, and the contributions
of odorants were different depending on the facilities
located in each site. Especially, the RSCs contributionwas very high
in some residential sites while the other residential sites showed
different results. The OI values obtained from RMR were higher
than the COI values obtained from instrumental analysis. This
suggests that a clear guideline is necessary to determine the
emissions standards in Korea. A strong correlation was found between
the OI by RMR and COI/SOAV by instrumental analysis. The
RMR method was effective to understand the characteristics of
odorants emissions from the SSIA. From this study, an odor problem
was found to be serious in the SSIA; therefore, further research is
necessary to find major odor sources and to control odor emissions
