Abstract

최근 미세먼지가 사회적 이슈가 됨에 따라 지하철 시스템의 공기 질에도 많은 관심이 쏠리고 있다. 지하철 미세먼지는 지상과 달리 폐쇄적인 환경이라는 특징이 있는데, 이로 인해 발생 및 유입된 미세먼지는 지하철 시스템에 축적된다. 지하철 미세먼지의 대부분을 차지하는 미세마모입자들은 철 성분을 주축으로 다양한 중금속 성분을 포함하므로 인체에 해롭다. 본 기고문에서는 이러한 지하철 미세먼지 및 미세마모입자에 대한 기본 지식과 미세마모입자의 주된 발생원인 휠-레일 접촉 미세먼지발생 연구에 대해 소개하고자 한다. 연구 결과들은 지하철 공기 질 향상을 위해 미세마모입자 발생 저감에 기여할 것으로 기대된다.
