입자상 물질의 악영향은 무엇인가? | 대기오염물질 중 입자상 물질(Particulate Matter; PM)은 천식 악화, 만성폐쇄성폐질환 등 호흡기계 관련질환1-3)과 불규칙한 심장박동, 혈관 기능 장애, 부정맥 등 심혈관계 관련질환 발생위험4-6)을 높이는 것으로 보고되었다. 또한 세계 여러 지역을 대상으로 한 연구에서 입자상 물질은 급성 및 만성 조기사망과도 유의한 관련성이 있는 것으로 보고되었다. | |
입자상물질은 크기에 따라 어떻게 구분할 수 있는가? | 입자상 물질의 크기와 성분은 매우 복잡하고 다양하며, 입자의 크기, 표면적, 화학적 조성이 건강영향을 결정하게된다.14-16)입자상물질은크기에따라 TSP(Total Suspended Particle), PM10(Particulate Matter less than 10 μm in diameter), PM10-25 (Particulate Matter in the 2.5-.10 μm range), PM2.5( Particulate Matter less than 2.5 μm in diameter)로 구분할 수 있다. | |
본 연구의 몇 가지 제한점은 무엇인가? | 본 연구에서는 몇가지 제한점이 있다. 첫째, 미세먼지(PM10)와 초미세먼지(PM2.5)의 농도 자료는 대기질 측정망자료를 사용하였다. 노출자료는 개개인의 노출 측정자료를 적용하는 것이 바람직하지만 시간적, 경제적 제약으로 개인 노출자료를 생산 및 적용하는 것이 어려우므로 본 연구에서는 대기질 측정망자료를 이용하였다. 둘째, 본 연구에서는 시계열연구의 GAM모형을 적용하기 위해 미세먼지(PM10)와 초미세먼지(PM2.5)의 서울시 평균 농도를 적용하였다. 미세먼지(PM10)와 초미세먼지 (PM2.5) 농도는 지역에 따라 차이가 크므로 지역의 대기오염 농도를 반영하는 환자-교차연구 등의 통계분석방법을 적용한 분석이 향후에 진행되어야 할 것이다. |
