초록

본 연구에서는 토지피복유형에 따른 바이오에어로졸 중 배양성 세균분포를 파악하기 위하여 충청북도 충주시에 위치한 3가지 유형을 대상으로 실시하였다. 토지피복에 따른 기상요소와 바이오에어로졸을 조사하여 측정지점별 미기상변화에 따른 세균 분포를 비교·분석할 수 있었다. 측정지점별 미기상 중 기온의 차이는 도시 숲 8.7℃, 수변 녹지 10.8℃, 도심지 10.2℃로 측정지점 중 도시 숲이 가장 낮은 기온 값을 보였으며, 상대습도는 도시 숲 61.8%, 수변 녹지 59.3%, 도심지 55.7%로 도시 숲이 가장 높은 것으로 분석되었다. 동정된 세균은 43속 99종으로 나타났다. 배양된 세균의 종 다양성 측면에서는 수변녹지 22속, 도시 숲 21속, 도심지 17속으로 조사되었으며, 종수의 경우 수변녹지 37종, 도심지 31종, 도시 숲 31종으로 나타났다. 3가지 유형의 측정지에 모두 존재하는 종은 Bacillus toyonensis와 Pseudarthrobacter oxydan으로 나타났으며, 또한 도시 숲과 수변녹지와 같은 녹지지역에서 존재하는 Herbiconiux flava종을 확인하였다. 측정지점별 미기상환경에 따른 세균농도의 변화를 분석한 결과 도시 숲 333CFU/m3, 수변 녹지 287CFU/m3, 도심지 173CFU/m3 순으로 나타났으며, 미기상 중 기온변화에 따른 측정지점별 농도변화는 미비하였다. 그러나 상대습도와 풍속은 농도변화와 유사한 경향을 보인 것으로 분석되었다. 따라서 본 연구에서는 토지피복유형에 따른 바이오에어로졸 중 배양성 세균의 분포 정도를 파악하여 측정지점별 바이오에어로졸의 특성을 비교·분석하여 추후 건강한 도시 관리 및 녹지조성의 기초자료를 제공하고자 하였다.

This study surveyed three land cover types in Chungju City in Chungcheongbuk Province to check the distribution of cultured bacteria in bio-aerosols according to land cover type. It was possible to compare and analyze the distribution of bacteria according to microclimatic changes at each measurement point by examining meteorological factors and bio-aerosols according to land cover. The microclimate temperature in each measurement point was 8.7℃ for the urban forest, 10.8℃ for the waterside green area, and 10.2℃ for the urban area, indicating the urban forest had the lowest temperature among the measurement points. The relative humanity was 61.8% fin the urban forest, 59.3% in the waterside green area, and 55.7% in the urban area, indicating that the urban forest was the most humid among the measurement points. The identified bacteria were found to be 43 genera and 99 species. In terms of species diversity of cultured bacteria, 22 genera were found in the waterside green area, 21 genera in the urban forest, and 17 genera in the urban area, 37 species were found in the waterside green area, 31 species in the urban area, and 31 species in the urban forest. Bacillus toyonensis and Pseudarthrobacter oxydan were the species present in all three types of measurement sites, and Herbiconiux flava was confirmed to inhabit green areas such as urban forests and waterside green areas. The analysis result of the bacterial concentration according to the microclimatic environment in each measurement point was 333 CFU/m3 in the urban forest, 287 CFU/m3, in the waterside green area, and 173 CFU/m3 in the downtown area. The relative humidity and wind speed were analyzed to show a similar trend as the concentration. This study is expected to provide basic data for healthy urban management and green area creation by identifying the distribution of cultured bacteria in bio-aerosols according to land cover type and comparing and analyzing the traits of bio-aerosol in each measurement point.
