Measurement, Analysis -
Contributing to formulating odor reduction measures at facilities and creating a pleasant living environment through precise measurement and analysis of odorous substances (using precision equipment analysis)
Relevant regulations“Odor Prevention Act" Article 7 (Emission Standards), and Article 14 (Recommendations for Improvement) of the same Act.
Facilities subject to odor measurementFacilities, machinery, equipment, and other items designated by the decree of Ministry of Environment that are capable of generating odors
Measurement, Analysis ItemsComplex OdorsAn odor that stimulates the human olfactory sense by the combined action of two or more odorants, causing discomfort and aversion
“Odor Prevention Act" Article 2, Paragraph 4, and Article 8 of same act, Exhibit 3
Classification Emission Permission Standards (dilution rate) The range of stringent emission permission standards (dilution rate) Industrial Areas Other Areas 공업지역 Other Areas Emission ports 1,000 or less 500 or less 500 ~ 1,000 300 ~ 500 Site boundary line 20 or less 15 or less 15 ~ 20 10 ~ 15 Designated odorsThe 22 items that cause odors are referred to as designated odors. Through precise instrument analysis, it is possible to identify odor-causing substances with more accurate quantitative values than compound odors.
