초록

수도권에 있는 4개 도로터널을 선정해 오전 7시부터 오전 9시까지 미세먼지와 벤젠을 측정한 결과 PM10은 $111{\sim}268{\mu}g/m^3$으로 연간 대기환경기준치인 $50{\mu}g/m^3$을 2~5배 이상 초과하였고 PM2.5는 $35{\sim}65{\mu}g/m^3$으로 대기환경기준치인 $25{\mu}g/m^3$을 1.5배~2.5배 초과 하였다. 벤젠의 경우 300~500 ppb로 나타나 대기환경기준치인 1.5 ppb의 200~330배 초과하였다. 국내 장대터널에서 4개월 연속 측정한 결과 PM10의 경우 $30{\sim}400{\mu}g/m^3$으로 나타났고 Bag filter를 이용한 PM10의 제거효율은 97% 이상으로 나타나 향후 터널 내 대기질 개선에 기여할 것으로 판단된다. 벤젠의 경우 250~350 ppb로 측정되었다.
