  • 대기오염의 주원인이 되는 VOC는 자동차, 건축 등 도장분야에서 '96년기준으로 343,258톤/년이 발생되고 있으며 '94년 기준으로 국내 5개 정유회사의 정제 및 저장시설에서 년간 7,687톤, 출하시설에서 21,889톤이 배출되고 있으며 그 밖에 350개사의 페인트 제조업회사와 비디오 테이프 등의 세정공장에서도 상당량이 발생되는 등 매년 증가 일로에 있다.(중략)

  • VOCs의 제어를 위하여 흡착법이 널리 사용되는데 흡착제로서 다공성 탄소가 가장 뛰어남을 보여준다. 이를 resorcinol-formaldehyde과 $Na_2CO_3$으로 졸-겔법으로 메조포러스 xerogels을 제조하고 VOCs의 대표적인 물질인 톨루엔을 흡착시켜 흡착효율을 연구한 결과 흡착효율이 뛰어남을 알 수 있었다.

  • 산업화가 진행되면서 우리나라에서도 90년대 초반부터 악취문제가 점차 사회적인 관심거리로 등장하게 되었다. 1995년 대기환경보전법상에 휘발성유기화합물질 규제 규정을 신설하였으며 1996년에 여천지역을 환경오염으로 인한 특별대책지역으로 지정하였다.<중략>

  • Korean Photochemical Assessment Monitoring Stations (PAMS) have been established since the late 2001 to monitor ambient air concentrations of VOC species, which would enhance understanding photo-chemical formation of ozone and subsequently contribute to developing efficient ozone control strategies. The present study aims at identifying major VOC species and examining their trends by analyzing PAMS monitoring data collected from the year 2006 to 2016. All the 18 PAMS sites operated by the Ministry of Environment were included in the study. PAMS monitored the 56 target VOC species, which are classified into four groups, alkenes, lower alkanes ($C{\leq}3$), higher alkanes ($C{\geq}4$), aromatics. The higher alkanes and aromatics dominated over the lower alkanes and alkenes in the type 2 and 3 PAMS sites except Joongheung site. N-butane was a major alkane species, toluene was a major aromatic species and most of VOCs showed decreasing trends in these sites. On the other hand, only the alkenes showed decreasing trends at the Joongheung site in Yeosu. Major sources of abundant species such as ethane, propane, n-butane, toluene were estimated by analyzing seasonal variations, correlation with other VOC species, and emission profiles. A major source of n-butane was identified as LPG cars, while major sources of toluene varied considerably from one site to another. The lower alkanes were composed of ethane and propane, both of which showed a strong seasonal variation, low in the summer and high in the winter, indicating that a major source might be the heating by gaseous fuels. Ozone formation potentials of VOC species were evaluated by applying MIR and POCP to the measured VOC species concentrations. Toluene contributed the most to total ozone forming potentials followed by m,p-xylene for all the type 2 and 3 PAMS sites except for two sites in Yeosu-Gwangyang. Ethylene and propylene were the first and second contributors to total ozone forming potentials at Joongheung site in Yeosu.
