Abstract

This study was conducted to measure the concentrations of total culturable bacteria (TCB) and to identify the bacteria in thirty public facilities (7 elderly-care facilities, 4 hypermarkets, 4 university hospitals, 7 child care facilities, 4 subway stations and 4 bus terminals) in Seoul and Gyeonggi-Do Province. Although all concentrations measured in these study facilities did not exceed the national maintenance standard, it is believed that elderly-, child-care facilities should be high priority facilities to improve the indoor air quality and it is important to study the health effects and the airborne bacteria concentration of public facilities including non-culturable bacteria or allergen.

실내 공기 중 부유세균은 실내공기오염을 유발하고 재실자의 건강상 위해를 초래할 수 있다. 본 연구는 다중이용시설을 대상으로 주요목적으로 사용되는 실내에서 부유세균의 농도와 세균의 종류를 동정하고 실내공기오염물질 중 부유세균에 대한 기초정보 제공을 목적으로 한다. 노인시설 7개소 (노인요양시설, 노인전문병원, 복지관 포함), 대규모점포 4개소, 대학병원 4개소, 어린이집 7개소 (유치원, 어린이집, 보육원 포함), 지하역사 4개소 및 버스터미널 4개소 등 총 30개소 120개 지점에서 총부유세균의 농도를 측정 분석하고 세균의 종류를 동정하였다. 모든 시설군에서 측정된 실내 부유세균의 농도는 유지기준 $800CFU/m^3$이하 이었으나, I/O비가 1.09-2.36으로 실내의 총부유세균의 농도가 실외에 비해 높았고, 어린이집, 대학병원, 노인시설에서 동정된 세균의 종류별 높은 검출빈도 보였다. 국내 다중이용시설의 주요목적에 따른 실내 부유세균에 대한 지속적 관찰이 필요하며, 특히 어린이집, 대학병원, 노인시설 등에 대한 관심이 요구되고, 추후 배양 가능한 세균 뿐 아니라 알레르겐 등을 포함한 미생물학적 실내오염물질에 대한 추가 연구가 필요할 것으로 사료된다.
