본 연구에서는 광주 하남산업단지 내 도장, 도금, 주물․주조, 고무제조, 폐유정제사업장을 대상으로 사업장별로 발생되는 악취물질 중 악취기여도가 큰 물질을 조사하고자 하였다. 이를 위해 방지시설 배출구에서 질소화합물 2종, 황화합물 5종, 알데하이드류 13종, 휘발성유기화합물 10종, 총 30항목을 조사하였다. 조사결과 악취기여도가 큰 물질은 도장사업장에서는 뷰틸알데하이드(73.8%) > 아세트알데하이드(17.7%) > 프로피온알데하이드(4.9%) 순으로 나타났고, 도금사업장에서는 아세트알데하이드(59%) > 암모니아(19.1%) > 황화수소(13.1%) 순으로 나타났다. 그리고 주물․주조사업장에서는 황화수소(65.9%) > 아세트알데하이드(17.2%) > 이산화황(5.2%)으로 나타났다. 그리고 주물․주조사업장에서는 황화수소(65.9%) > 아세트알데하이드(17.2%) > 이산화황(5.2%) 순으로 나타났으며, 고무제조사업장에서는 I-발레르알데하이드(35.0%) > 뷰틸알데하이드(32.0%) > n-발레르알데하이드(13.3%)으로 나타났다. 폐유정제사업장에서는 아세트알데하이드(36.8%) > 뷰틸알데하이드(33.6%) > 이산화황(14.5%) 순으로 나타났다.


In this study was analyzed substances that high contribute to odor strength degree which emitted from the painting, the plating, the casting, the rubber manufacturing, and the used oil refining facilities in Gwangju Hanam industrial complex. In order to this, we analyzed two types of nitrogen compounds, five types of sulfur compounds, thirteen types of the aldehyde, and ten types of volatile organic compounds discharged from an outlet for antipollution facilities. The results are as following high contribution rate sustances to odor strenth was ordered butylaldehyde (73.8%) > acetaldehyde (17.7%) > ropionaldehyde (4.9%) at painting facilities. At plating facilities, it was ordered Acetaldehyde (59.0%) > ammonia (19.1) > hydrogen sulfide (13.1%). At casting facilities, it was ordered Hydrogen sulfide (65.9%) > acetaldehyde (17.2%) > sulfur dioxide(5.2%). At rubber manufacturing facilities, it was ordered i-valeraldehyde(35.0%) > butylaldehyde (32.0%) > n-valeraldehyde (13.3%) and at used oil refinery facilities, it was ordered Acetaldehyde(36.8%)> butylaldehyde (33.6%) > sulfur dioxide (14.5%).
