On-line GC-PID를 이용한 부천시 대기 중 BTEX 농도 분포 특성에 관한 연구 = The Characteristic of BTEX Distribution in Bucheon City using On-line GC-PID

다국어 초록 (Multilingual Abstract)

This research carried out to study on the characteristic of daily variation for ambient BTEX in Bucheon techno-park area by using the on-line GC-PID system. The average concentrations of BTEX in this study were : 2.13 ± 1.11 ppb, 15.33 ± 16.03 ppb,1.43 ± 1.64 ppb, 2.82 ± 2.75 ppb, and 0.50 ± 0.72 ppb, for benzene, toluene, ethylbenzene, m,p-xylenes, and o-xylene,respectively. The toluene concentration was very higher than the other compounds. The hourly variations were indicated that the toluene, ethylbenzene, m,p-xylenes were increasing from 06:00 to 12:00 and sightly decreasing at nighttime except benzene.
The correlations between the concentrations of BTEX compounds were high, suggesting traffic as a common source. The benzene-to-toluene ratios were about 1:8. The measurement data for BTEX were fit by probability density function curves that the probability of exist in ambient benzene was estimated more about 50 percent at above 2.0 ppb (6.96 μg/m3) level. These level of benzene concentration was not only exceed the local guidelines but three times higher than the WHO recommended that the lifetime exposure to concentrations of 1.7 μg/m3 may cause 10 cases of leukaemia per million of inhabitants.

국문 초록 (Abstract)

본 연구는 부천시 테크노파크 지역의 대기 중 BTEX 농도의 일변화 특성을 GC-PID 시스템을 이용하여 분석하였다. 이 지역의 BTEX 평균농도는 벤젠, 톨루엔, 에틸벤젠, m,p-자일렌 및 o-자일렌이 각각 2.13 ± 1.11, 15.33 ± 16.03, 1.43 ± 1.64,2.82 ± 2.75 및 0.50 ± 0.72 ppb로 나타났으며, 톨루엔의 농도가 다른 화합물보다 높은 것으로 분석되었다. 시간적 변화 특성을 살펴보면 벤젠을 제외한 화합물들은 주간에 지속적으로 증가하다가 야간에 조금씩 감소하는 것으로 나타났으며, 이는 교통수단의 영향을 받고 있는 것으로 판단할 수 있다. 특히 벤젠의 평균 농도는 지역 기준뿐만 아니라 세계보건기구의 권고치보다도 훨씬 높은 수준을 나타내어 이와 관련된 대책이 필요할 것으로 보인다.
